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.
