China's single-plant production of the largest automotive tire production line was completed and put into operation on September 6, 2010 in Fuxin District, Xianyang City, Shaanxi Province, and 20 million all-steel radial tires of Shaanxi Yanchang Petroleum Group were rolled off the production line.
In the country's longest and most spanned all-steel radial tire plant, it covers an area of ​​more than 90,000 square meters. The first phase of 600,000 all-steel radial tires was put into production in the first phase, ending the history of Shaanxi province without radial tires, and Shaanxi Automotive Industry. The realization of a complete industrial chain "Shaanxi manufacturing." After all the projects have reached 20 million radial tires, they can achieve an annual sales value of 12.7 billion yuan and provide 6,200 jobs.
All-steel radial tires adopt high-performance new-type tire stock materials and low heat-generating rubber formulas are the world's highest environmental standards and technologies for the tire industry.
Shaanxi Yanchang Petroleum Group is the largest enterprise in Shaanxi Province with an annual sales income of over 100 billion yuan. The commissioning of all-steel radial tires marks the extension of Shaanxi Yanchang Petroleum from energy and chemicals to the automotive industry.
PTA Powder
Main application:Repair and strengthen workpiece surface, significantly
Welding method:PTA welding
Main equipment:PTA welding machine
Flame core temperature: about 10000℃
Technological characteristics:PTA has high temperature, concentrated energy, stable combustion, small heat affected zone, fast welding speed, high production efficiency, easy to obtain low dilution rate of surfacing layer, surfacing layer and workpiece matrix are metallurgical bonding,, bonding strength is high.
PTA welding technology is one of surface strengthening methods, which has high deposition rate, low dilution rate, and could be applied with many kinds of powder. The manufacturing craft of PTA powder is normally gas atomization, which reduces satellite of powder. We supply 4 main categories of PTA powder: Nickel-based alloy powder, Iron-based alloy powder, Cobalt-based alloy powder and Mixed Powder.
Nickel Based Alloy Powder possesses high temperature resistance and wear resistance, it is the most popular alloy powder applied by PTA welding both domestically and internationally. Coating hardness is within the range of HRC 30-60. It could be applied to various industries like agriculture, plastic, paper, marine and steel making where wear and corrosion protection needed. Some examples are plunger, moulds, pump leaf and screw.
Iron Based Alloy Powder is more widely used and a more economic choice. With high abrasive resistance, it is more commonly applied to mining tools, drilling tools and mixers of iron and steel making industry, coal industry, shaft, oil and energy industry.
Cobalt Based Alloy Powder is recommended for corrosion and oxidation resistance, with better hot hardness values than equivalent Nickel based alloy powder. It is widely applied to steel making industry, coal industry and mining industry.
Mixed powder mainly refers to NiCrBSi mixing with other hard-phase powder such as cast tungsten carbide and other cemented alloy powder, which allows the powder better hardness around HRC60 and excellent abrasion resistance.
Mixed powder is more often used for mining equipment for oil sands, lignite, oil drilling tools, excavator buckets, extrusion screws for plastic processing, grain and oil processing, etc.
