In order to solve the problem of utilization of repair cylinders. A stainless steel rolhng compound process engineering methods is established. It calculated and analyzed the feasibility and reliability of insert repair for hydraulic support column cylinder, and draw a series of key technologies parameter and calculation analysis methods, such as cylinder＇s minimum wall thickness for insert repair, the maximum limit size of cylinder port, cylinder hole safety coefficient, stainless steel set＇s maximum thickness, and so on. Formulating process route, developing a prototype, making the laboratory tests. It realized properties＇s compound optimization of stainless steel and alloy structural steel. Batch production application on the mining face show that stable the performance being, nearly twice the service life improving and remarkable the technical and economic benefit being. At the same time, for expanding stainless steel rolling compound process engineering methods＇ application space, a reliable technical theory basis is made.
