The shell thickness of the thin-wall high-efficiency roller is only 50%-70% of that of a standard roller. The internal design reduces the area occupied by screw ribs, thereby increasing the contact area and heat transfer efficiency of the cooling water. To offset the reduced strength due to the thinner shell, an integral arc-shaped flow channel is adopted to enhance pressure resistance. Under identical operating conditions, the sheet equipment using the thin-wall high-efficiency roller can increase production by 20%-50%.
Roller surface treatment
● Tempered to ensure dense microstructure
● Deep quenching on the outer surface, achieving a hardness of HRC50~55
● Electroplated with hard chrome, achieving a hardness of HRC58~65
Surface finishing
● Mirror, super-mirror grinding and polishing
● Can be processed into various matte, frosted, sandblasted, and spray-coated surfaces
