The NTE260 electric wheel mining truck is suitable for large-scale open-pit coal mines with high safety factor and strong operability. Its control cabinet can not only control the forward, backward, turning of the whole vehicle, but also can control the special functions such as anti-smashing and anti-skid control on the ramp. It is understood that vehicles of the same type were previously imported from abroad. In 2009, the company began to independently research and develop NTE260 electric wheel mining vehicles. In 2011, it successfully developed electric wheel mining vehicles with China's independent intellectual property rights and delivered them to customers.
At present, after the early use of the Baiyun mining area, the NTE260 electric wheel mining vehicle has a failure rate of less than 3%, and its monthly transportation capacity is nearly 300,000 tons. Not only has it reached the advanced level of the same type of vehicle, but productivity has also been greatly improved.
The successful development of the NTE260 electric wheel mining vehicle has become a successful model for the Group's independent innovation. This year, the company will fully plan the top-level design work of the national-level engineering research center, earnestly give play to the advantages of its leading industry company in the northern joint-stock company, and strengthen and optimize the mining vehicle product segment.

Iron-based alloy powder is commonly used in plasma transfer arc welding (PTAW) due to its excellent mechanical properties and high resistance to corrosion and heat. This type of powder is typically composed of iron as the base metal, along with various alloying elements such as nickel, chromium, molybdenum, and tungsten.
The specific composition of the iron-based alloy powder may vary depending on the desired properties and application requirements. For example, adding nickel can increase the strength and toughness of the weld, while chromium enhances the corrosion resistance. Molybdenum and tungsten are often added to improve the high-temperature strength and creep resistance of the weld.
Iron-based alloy powders for PTAW are available in various particle sizes, typically ranging from a few micrometers to several hundred micrometers. The powder is usually fed into the plasma arc through a powder feeder, which ensures a controlled and consistent supply of powder during the welding process.
During PTAW, the powder is melted and deposited onto the workpiece, forming a weld bead. The high energy plasma arc provides the heat necessary to melt the powder and the base metal, creating a strong and durable weld joint.
Overall, iron-based alloy powder for plasma transfer arc welding offers excellent weldability, high mechanical properties, and resistance to corrosion and heat, making it suitable for a wide range of applications in industries such as aerospace, automotive, and power generation.
