ROLE FOR SUPPORTING AND TRANSPORTING HOT GOOD, METHOD FOR PRODUCING THE ROLE, METHOD FOR RECONSTRUCTING A PROTECTED ROLE, WELDING ADDITIVE MATERIAL AND WELDING WIRE FOR PRODUCING ORDER WELDING

摘要

The invention relates to a roller for supporting and transporting hot material with a roller body comprising a roller shell made of a base material and a wear layer applied by a build-up welding on the base material with a welding filler wear layer, which includes the roller shell surface. To increase the service life of the wear layer, improve the wear resistance and reduce the manufacturing costs of the weld, a role is proposed in which the base material of the roll shell is steel and up to 0.45% C, the build-up welding is designed as a deposit welding and the The invention further relates to a process for producing the roll, a process for the restoration of a worn roll, a filler metal and a welding wire for producing the hard facing.
