Resumo
In today’s modern hot strip mill, productivity, efficiency and strip surface quality are essential for long term success. For the late stands, the traditional Alloy Indefinite Chill (AIC or ICDP) roll materials work well but do have limitations in surface quality which can result in unscheduled roll changes and special cascading practices. For this purpose, Enhanced Alloy Indefinite Chill roll materials were developed which utilise optimised roll microstructures that provide uniform wear of the surface for superior strip surface quality as well as provide consistency of these properties through life. The APEX Enhanced Carbide AIC roll has proven successful for the late stands of a large variety of mill applications. The unique microstructure of APEX has proven to result in superior surface finish along with maximum resistance to crack initiation and growth. The resistance to wear of the barrel profile has also resulted in minimization of stock removals during grinding which have improved the cost effectiveness of the roll material.
