Remanufacture of copper alloy deposited on the inner surface of the cylinder barrel of the pillar of hydraulic support in coal mine

2022-11-27

The company develops and uses the double hot wire TIG technology to recover the 27SiMn cylinder of the hydraulic support that is scrapped or about to be scrapped, and restore the original service performance of the cylinder, so as to achieve the remanufacture of the cylinder. The current price range of performance has reached 4-8 times the life of the new cylinder; Hot wire TIG is adopted, which has good welding protection, no spatter and stable welding quality. It completely replaces the electroplating process to achieve remanufacturing effect, greatly reducing production costs and improving production efficiency. Since the beginning of 2017, various types of cylinder blocks with diameters ranging from 160mm to 550mm have been coated with aluminum bronze for the inner wall of Shenhua cylinder.

The company has successfully applied for the invention patent of Sintering Trolley Welding Repair Process

2022-11-27

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.
