To improve the service performance of Cr-series steel for cold roller, the combined effects of chromium and silicon on hardness and wear resistance of cold roll steel had been studied in this paper on the basis of MC5 cold roll steel. The results showed that, with increasing Si content the hardness tended to decrease when Cr content was about the same.

High-speed steel cast-iron rolls were developed around 1990 and have been widely used for the earlier stand of hot strip mills. However, for the later stand of hot strip mills, the use of high-speed steel cast-iron rolls has been limited due to the insufficient crack resistance.
R.B. Tennent. J. Cameron. It is possible to use as-cast ESR steel for the manufacture of high-hardness cold-mill work rolls for which forged steel was formerly considered necessary. Production and ...
SAE 52100 grade high-carbon chromium steel has been a standard bearing material with 58 HRC hardness. It also contains Mn, Si, Ni, Cu, and Mo in small amounts. It can work up to 200°C while high speed steels can be used up to 320°C. These steels are not suitable in corrosive media but AISI 440 C stainless steel can be used.

His work investigated on the microstructure and mechanical properties of FeCrMoVC high-speed steel, which were fabricated with a diameter of 2.0 mm using a rapid solidification technique. Vanadium addition plays an important role in promoting the formation of skeleton carbides (V6C5 phase), hindering the rapid expansion of shear zone, and has ...
Structural Investigations of HSS Rolls for Hot Strip Mill Jacqueline Lecomte-Beckers Jerome Tchoufang Tchuindjang Roger Ernst Jean-Pierre Breyer ABSTRACT High Speed Steel (HSS) cast rollsare used in front finishing standsof hot strip mills (HSM). Good wear resistance and hardnessat high temperatures, are defining featuresof HSS.
Abstract The continuous cooling transformation (CCT) curve of a new type of high speed steel (HSS) for rollers was determined along with its typical microstructures. The CCT curve established shows that the Ac1 of the steel is 770∼830 °C, the Acm is 920 °C and the starting temperature of martensite transformation is 190 °C. The Fe–C isopleths, mass fractions of all the phases and mole ...
The 4-high mill is equipped with positive and negative work roll bending in order to influence the shape and the flatness of the strip. Either the work roll or the back-up roll is driven, depending on customer requirements. The diameter of the 4-high work rolls amounts to approximately 1:4 in …
