Development of High Performance New Composite Roll.

Abstract

Recently work rolls for cold rolling mill have been required for higher toughness because of remarkable progress in rolling mill, in addition, demands for higher wear resistance of rolls and lower damage of rolls in the accident of rolling have been increasing more and more. The new composite roll by the rotational electroslag remelting (ESR) bimetallic method was developed in order to satisfy such various demandsat the same time.
