2021-5-6 In recent years several tests have been performed with centrifugally cast bimetallic rolls as work rolls in cold rolling. This paper outlines the exciting results from cast rolls made in a special type of alloyed steel called Semi-HSS used in a temper mill at Siderar (Argentina). In this specific application of cold rolling it is very important imprinting to the sheet not only the desired mechanical properties but also a particular surface aspect. The work roll surface and especially its deterioration during the campaign become of primary importance to establish the real behaviour of roll grade material. In this temper mill, the use of cast Semi-HSS

Description And Tech Data. High Speed Steel Rolls. The microstructure consists of tempered bainitic / martensitic matrix with primary and secondary carbides. Primary carbides MC, M 7 C 3, M 6 C and M 2 C are originated during the eutectic solidification. Secondary carbides are precipitated during the High Temperature quench and tempering.

2009-10-1 The effect of austenitizing temperature on the microstructure and mechanical properties of semi-high-speed steel (S-HSS) cold-forged rolls was investigated. Low-temperature austenitizing below 1313 K induced carbide coarsening during subsequent tempering at 973 K due to the nucleation effect of undissolved M7C3. On the other hand, the heavy dissolution of M7C3 above 1353 K caused the fine ...
