Hardness testing of spun cast high chrome iron roll


Spun Cast High Chrome Iron Rolls
:

These rolls are suitable for use at early finishing stands of Hot Strip Mills. It gives very high resistance to abrasion and wear coupled with high degree of resistance to thermal fatigue. The shell matrix consists of complex carbides in martensitic matrix without graphite. Mechanical strength of shell metal is enhanced through special heat treatment cycles and thus the hardness drop in the shell layer is practically negligible. There are numerous benefits of using these rolls, it improves resistance to crack initiation and propagation, it gives tolerance to mills conditions, the hardness throughout the working life is uniform, thus ensuring roll gap profile consistency and complete flexibility during operations.

Application: These rolls are used as work rolls in the front finishing stands of Hot Strip Mills and work Rolls for Heavy Plate Mills.
