METHOD OF MANUFACTURE OF WEAR-RESISTANT BIMETALLIC STRIPS Russian patent published in 1998 - IPC

FIELD: manufacture of bimetallic facing strips protecting the equipment surface against damages and wear under the action of impact loads, for instance, in metallurgical industry. SUBSTANCE: plates of plastic non-harden metal are faced with a wear-resistant protective coating of harden hard metal. Built-up plates are heated and rolled; heat-treated and mechanically worked at the ends until the preset parameters are obtained around the edges. After joining of plates of non-harden metal for attachment to the surface to be protected. They are bolted jointly. Bolts are installed in the holes in interference fit. Assembled plates are subjected to hardening and tempering. Hardened built-up layer is separated and ground. The opposite nonhardened surface of plastic metal is worked until the required strip thickness is obtained. EFFECT: facilitated procedure. 2 cl, 2 dwg
