The company has successfully applied for the invention patent of Sintering Trolley Welding Repair Process
The sintering machine trolley is an important spare part of the sintering machine, and its working environment is bad. Its intermediate body is nodular cast iron. Due to the bad working environment, the intermediate body of the sintering machine trolley will crack after being used for a period of time, resulting in deformation, and the trolley will be scrapped. If welding can be carried out successfully, it will bring great economic and social benefits.
The intermediate of sintering trolley is nodular cast iron, and the difficulty of welding cast iron is recognized by the welding industry.
For many years, many steel mills have organized specialized personnel to tackle technical problems, but they have not succeeded. After research, our company's technicians successfully overcome this problem and applied for relevant patents.
