【Abstract】 According to lower wear resistance and easier wear abrasion of rotor blade in sintering exhaust fan,proper electric current of carbon arc build-up welding and the technological parameters of injection welding are altogether selected for surface hardening by use of high chromium cast iron and injection welding alloy powders.Service life of blades after surface hardening is increased by 0.75 times compared with orginal ones.更多还原
