After receiving the 13 million yuan acquisition invitation from Gree Electric Appliances, Yinlong New Energy became the focus of market chasing and discussion. The "Securities Daily" reporter also went to the Yinlong New Energy Automobile Factory in Wu'an City, Hebei Province. In the Yinlong New Energy Industrial Park, the reporter saw that the new factory was just completed, and the robot's arm waved in the factory. From time to time, there were staff members operating the machine. A person in charge of Yinlong New Energy said: "This is the world's largest lithium titanate material and battery production base, and it is a collection of fully automatic, efficient and industrialized new energy vehicle industry chain." After Gree announced that it will spend 10 billion yuan to acquire Yinlong New Energy, the acquisition of Gree and the technical path and valuation of Yinlong New Energy were widely discussed in the market. In this regard, Yin Jincang, chairman of Yinlong Group, said in an interview: “The company’s order volume has grown rapidly. The company will usher in high sales growth this year and next year, and the undervaluation of valuation does not exist.†And Dong Mingzhu, chairman of Gree Electric, revealed that his plan is to allow Gree to enter the target of 200 billion yuan enterprises through the acquisition. Lithium titanate route High-speed expansion within one year In a brand-new factory in Yinlong, the "Securities Daily" reporter noticed that the wall was marked with the "20 days of production". A worker told the reporter: "This plant was put into production for about 20 days. It was expanded on the basis of the original. The expansion of production was accompanied by the introduction of new technology. The production of the plant was extended upstream of the new energy vehicle, and the material of the battery was also carried out. produce." At the time of the large-scale development of new energy vehicles, most domestic manufacturers chose the lithium iron phosphate technology route, while Samsung and other foreign brands chose ternary lithium. In the choice of different technical routes of batteries, Yinlong New Energy did not choose the market. The conventional route, but the independent research and development road of lithium titanate. A large part of the new plant of Yinlong New Energy, which was seen by the reporter, is producing lithium titanate batteries. At present, Yinlong plans to expand the production line of lithium titanate batteries. According to the plan, it wants to use the unique lithium titanate technology as the core to build a strategic layout of the closed cycle industrial chain of new energy vehicle powertrain and vehicle R&D, production and sales. However, this battery technology is still in the market discussion, and the market has different opinions on its advantages and disadvantages. Yinlong New Energy related person said that although the energy density of lithium titanate is theoretically lower than that of lithium iron phosphate and ternary lithium, Yinlong has passed the continuous research and development of the energy density of lithium titanate battery in the past three years. It has increased by 40% and still maintains the characteristics of 6 minutes of fast charging and 30 years of cycle life. Under the support of relevant national policies, the broad prospects of new energy vehicles have enabled Yinlong New Energy to taste its sweetness and accelerate the pace of capacity expansion. Many reporters learned that in the past year, Yinlong's factory building is expanding rapidly, and its production capacity will be greatly improved through these newly built factories. In the days when Gree’s acquisition of Yinlong’s news came out, Yinlong’s expansion was faster. According to official data, from January to August this year, Yinlong New Energy sold a total of 1,844 buses. According to the overall sales situation of the industry, Yinlong New Energy ranked seventh in the industry in the first eight months, and the growth rate is very rapid. Wei Yincang revealed that Yinlong New Energy Commercial Vehicles currently has an annual production capacity of 10,000 vehicles, and will reach 30,000 vehicles next year. In 2020, it will expand to 100,000 production capacity, and will also promote passenger car manufacturing. Regardless of the acquisition results of Gree, the large-scale construction investment of Yinlong New Energy is emerging. This time, Yinlong New Energy announced a number of major events, including the completion and commissioning of the fourth generation of high energy density lithium titanate nanomaterials and the fourth generation of high-energy batteries, the completion and commissioning of fast-charging passenger cars and logistics vehicles, and the Austrian titanium The foundation of the period and the inauguration of the Austrian Nanomaterials Research Institute. “The peak demand for new energy vehicles is in the second half of the year. At present, the company has received a large number of orders, but most of them are complete vehicles. There are very few orders for batteries. At present, the batteries we produce will be supplied to the vehicles produced by ourselves. In addition to the demand, we only consider the external sales, the battery is in a state of sales more than supply. The capacity of our battery is still expanding." Yinlong New Energy insiders told reporters. He told reporters that the current Yinlong new energy vehicles are mainly supplied to cities such as Beijing, Handan and Zhuhai. This year, they will enter Shenzhen, Anhui and other places. Beijing has a sightseeing line that uses pure electric double-decker buses produced by Yinlong. “The demand in the Beijing market is constantly expanding.†Wei Yincang said that the company plans to invest about 35 billion yuan in the next five years, complete a total of about 650,000 new energy vehicles, achieve energy storage of more than 1500MWH, total power battery output of more than 4 billion ampere, total output of lithium titanium titanate It reached 42,200 tons and the output of the charging station was nearly 15,000. Li Yuheng, a researcher at CIC's new energy vehicle industry chain, said: "At present, many domestic new energy vehicle manufacturers are looking for financial support, and Gree, which has abundant capital flow, is a good partner. Gree is currently the world's largest R&D. In order to increase profits, Gree began to enter the new energy vehicle market in order to increase revenue. New energy vehicles have become the development direction of the future automobile market, coupled with the government's strong subsidies for new energy vehicles. Gree's willingness to transform to new energy coincides with the expansion needs of Yinlong." Accelerate upstream and downstream extension Gree wants to swallow the entire industrial chain After investigation, the reporter found that the opposite side of the reporter's factory is the assembly workshop of Yinlong New Energy Vehicle. At the same time, Yinlong has a whole vehicle production and assembly plant in Shijiazhuang. That is to say, Yinlong New Energy can completely produce and deliver vehicles from the production and processing of the entire production base in this production base. This base covers almost the entire industry of Yinlong New Energy Vehicle. chain. After Gree acquires Yinlong New Energy, it will control the entire industrial chain of new energy vehicles. The reporter learned that Fuxin Energy Automobile Industrial Park is part of the national strategic layout of Yinlong New Energy. After the acquisition of Gree, Yinlong New Energy will continue to expand to meet the production of the whole vehicle. Yinlong New Energy related person said that in the future, Yinlong New Energy plans to build Chengdu New Energy Industrial Park in Southwest China and Lanzhou New Energy Industrial Park in Northwest China. After being acquired by Gree, Yinlong New Energy will continue to exert its strength in technology research and development and innovation. In the expansion of the Yinlong New Energy Industrial Park, the production of upstream and downstream of new energy vehicles has been upgraded to the first place. For the expansion of battery materials and charging piles, Yinlong is accelerating. Spending a billion yuan acquisition Is it not worthwhile? After Gree announced that it would spend 10 billion yuan to acquire Yinlong New Energy, Gree’s disclosure of the acquisition triggered a hot debate, and the technical path and valuation of Yinlong New Energy were widely discussed in the industry. Some insiders believe that the suitability of lithium titanate battery technology selected by Yinlong New Energy has yet to be verified. At present, lithium titanate has weak points of low energy density and is unstable. However, some insiders also raised doubts about the high valuation of Yinlong New Energy in the Gree acquisition. Wei Yincang responded by saying: "Yinlong spent 10 years to pay 10 billion yuan in tuition to choose lithium titanate route for a reason." He does not deny that Yinlong's lithium titanate battery is better than other technologies such as lithium iron phosphate battery. There are weaknesses with low energy density, but its advantages of wide temperature, high safety, long life, and fast charge and discharge are worthy of attention. However, he said that according to relevant statistics, the average daily driving distance of passenger cars is about 50 kilometers, and about 90% of passenger cars are not used for long-distance operation. Regarding the market's doubts about the overvaluation of the acquisition, Wei Yincang said that the company is expected to achieve high sales growth this year and next year. The company is not worried about this issue because orders have been increasing rapidly. "We hope that through the acquisition, China will have more than one hundred and two billion yuan of enterprises born." For the acquisition target, Gree Electric Chairman Dong Mingzhu said. PERSONAL PROTECTION Welding Protection,Auto-Darkening Welding Helmet,Welding Gloves,Welding Glasses Changzhou Edaweld Trading Company Limited , https://www.edaweld.com
It is essential that the operator and helpers be properly clothed and protected because of the heat, ultra-violet rays, and sparks, produced by the arc welder (See Figure 3). For body protection a pair of fire retardant long sleeved coveralls without cuffs is a good choice. Always avoid clothing with tears, snags, rips, or worn spots as these are easily ignited by sparks. The sleeves and collars should be kept buttoned. The hands should be protected with leather gauntlet gloves. A pair o high top leather shoes, preferably safety shoes, is good protection for the feet. If low shoes are worn the ankles should be protected by fire resistant leggings. Eyes should be protected by transparent goggles if the person wears prescription glasses or safety glasses if not. A welding helmet or hand shield with filter plate and cover plate is mandatory for eye protection from the harmful rays of the arc. The filter plate should be at least shade #10 for general welding up to 200 amps. However, certain operations such as carbon-arc welding and higher current welding operations require darker shades. Never use a helmet if the filter plate or cover lens is cracked or broken. A flame-proof skull cap to protect the hair and head as well as hearing protection in noisy situations is recommended.
Plastic disposable cigarette lighters are very dangerous around heat and flame. It is very important that they not be carried in the pockets while welding. Always provide protection to bystanders or other workers by welding inside a properly screened area, if possible. If unable to work inside a screened area then protection to others should be provided by a portable screen or shield, or by their wearing anti-flash goggles.
SAFE OPERATION OF THE WELDER
It is important that anyone operating an arc welder be instructed on its safe use by a qualified teacher or welder.
Because of their potentially explosive nature, we strongly recommend that no welding, cutting, or hot work be attempted on used drums, barrels, tanks, or other containers under any circumstances.
If possible, work to be welded should be placed on a firebrick surface at a comfortable height. Welding should never be done directly on a concrete floor. Heat from the arc can cause steam to build-up in the floor which could cause an explosion. The welder cables should be positioned so that sparks and molten metal will not fall on them. They should also be kept free of grease and oil and located where they will not be driven over.
Electric welders can kill by electric shock. If the welding operation must be done on steel or other conductive material an insulating mat must be used under the operator. If the welding area is wet or damp or the operator is actively perspiring then he/she should wear rubber gloves under the Welding Gloves.
It is easier and safer to establish an arc on a clean surface than a dirty or rusty one. Therefore, metal should always be thoroughly cleaned by wire brushing or other method prior to welding. When chipping slag or wire brushing the finished bead the operator should always be sure to protect his eyes and body from flying slag and chips. Unused electrodes and electrode stubs should not be left on the floor as they create a slipping hazard. Hot metal should be handled with metal tongs or pliers. When quenching hot metal in water it should be done carefully to prevent painful burns from the escaping steam. Any metal left to cool should be carefully marked "HOT" with a soapstone. When welding is finished for the day or suspended for any length of time electrodes should be removed from the holder. The holder should be placed where no accidental contact could occur, and the welder should be disconnected from the power source.
SAFETY PRECAUTIONS FOR ENGINE POWERED WELDERS
Always operate in an open well-ventilated area or vent the engine exhaust directly outdoors.
Never fuel the engine while running or in the presence of an open flame.
Wipe up spilled fuel immediately and wait for fumes to disperse before starting the engine. *Never remove the radiator pressure cap from liquid cooled engines while they are hot to prevent scalding yourself.
Stop the engine before performing any maintenance or trouble shooting. The ignition system should be disabled to prevent accidental start of the engine.
Keep all guards and shields in place.
Keep hands, hair, and clothing away from moving parts.
FIRST AID
The welding area should always be equipped with a fire blanket and a well stocked first aid kit. It is desirable that one person be trained in first aid to treat the minor injuries that may occur. All injuries, no matter how minor they may seem can become more serious if not properly treated by trained medical personnel.
KEY POINTS TO REMEMBER
Be sure the welder is properly installed and grounded.
Never weld without adequate ventilation.
Take proper precautions to prevent fires.
Protect your entire body with fire retardant clothing, shoes, and gloves.
Wear eye protection at all times.
Weld only in a firesafe area.
Never do any welding, cutting, or hot work on used drums, barrels, tanks, or other containers.
Mark metal "HOT" with a soapstone.
Keep a well stocked first aid kit handy.
