Finishing Stand HSS Rolls

The microstructure of HSS roll shows fine and diffuse carbide of MC and M6C embedded in the Martensite. The performance of wear resistance, thermal hardness and thermal fatigue resistance of HSS roll is excellent.

1, Regarding the breakdown mill: due to the high temperature of steel, the roll should have relative high strength and steel-biting ability, moderate wearability and accident-resistant ability, thus improve the breakdown rate.

2, Regarding the intermediate stands: as roll pass changes, steel temperature dropping, we should focus more on non-uniformity between the bottom and two flanks of grooves, rolls should have relative strength, relative high fire-cracking resistance and wearability

3, Finishing stands: for this period, the temperature of steel is lowest, the speed of rolls are relatively fast, rolling capacity is relative small, to ensure the steel products surface quality and amount, we would focus on moderate hardness, hardness uniformity, hardness drop, thus to ensure every spot of roll pass wearability is the same, by which improve the amount and quality of rolled products, lower the steel cosuming, improve economic returns.
