Material selection, processing, and polishing of mirror rollers

　　1、 Material selection: Generally, seamless steel pipes are used for the roller body, and round steel and flange plates are used for the shaft head. Processing can be divided into turning and welding. Annealing treatment and drilling, annealing treatment of roller blanks to solve internal stress; One end of the steel roller shaft is turned flat on the end face and a standard center hole is drilled.

　　2、 Processing pattern: Process the pattern on the surface of the roller according to the customer's pattern requirements. This is a crucial part of the continuous casting roll production process, which requires the continuous casting roll production personnel to have rich experience and develop production processes based on customer pattern requirements. In the production process, the embosser should be careful, meticulous, and meticulous, and the patterns produced should be clear, rich in layers, and have a strong sense of three dimensionality.

　　3、 Chromium plating: After the pattern is completed, the surface of the roller body is plated with a hard chromium layer or sprayed with other materials to correct the static balance of the steel roller.

　　Mechanical mirror polishing is the polishing process (coarse grinding, fine grinding) and polishing of metal materials, which then achieves a smooth and bright mirror surface.

　　Chemical solution mirror polishing is the use of chemical solution immersion to remove surface oxides and achieve a bright effect.

　　Mechanical mirror polishing is a process of first polishing (rough grinding, fine grinding) on metal materials and then polishing (three-step polishing) to achieve a flat and shiny mirror like surface.
