C. Manufacturing standard & technical requirements
1、Roller is made of 42CrMo，normalizing heat treatment, hardness is HB220~260,surface overlaying of main shaft utilizes wear-resistant material while main shaft will be cooled by hollow cooling water.
2、Bracket is made up of upper & lower beam and left & right column, and it is connected by bearing pin and high strength bolts as a whole welding structure, material of main bracket is Q235 steel plate.
3、After welding, the stress of main bracket should be completely relieved in whole.
4、In order to guarantee the stable operation of rolling machine, wear of roller surface isles, extruding efficiency is good to prevent iron block from entering.
5、Main shaft bearing configures thermocouple to monitor temperature of bearing.
6、Normalizing treatment and ultrasonic inspection of roller main shaft should be implemented.
7、Painting of rolling machine should be even, color should be the same and there is no liquidity and drops hanging.
8、Control cabinet of rolling machine could configure central concentrated control connector, control cabinet PLC should be SIEMENS product.
9、Extruder base should comply with JC/T845-1999 industrial standard.
