Mainly used for six-roll mill of high precision cold-rolled strip steel

 the performance:
1, the good performance of the anti-fatigue
2, Can maintain a good shape
3, good thermal shock resistance
4, Good resistance to mechanical stress, thermal stress and organizational stress

the semi-high-speed steel products have the following three  characteristics:

1, Roller to ensure contact fatigue resistance of the premise is a high performance alloy
2, high hardness of carbides increased, greatly improve the wear resistance of the middle roller
3, to ensure the premise of hardness, semi-high-speed steel high-temperature tempering, and has a secondary hardening characteristics, enabling organizations to significantly improve stability, anti-roll accident ability is excellent.

the effects of using
the results of using semi-high-speed intermediate roll in four-stand Continuous Rolling Mill show that:rolling capacity from 6025.94 tons, increased to 9585.52 tons, increased 59.1%.
Sinosteel Xingtai Machinery & Mill Roll Co., Ltd. provides forge semi-high-speed steel intermediate rolls for cold rolling to domestic and foreign factories,The integrated use performance increase 60% and more than used normal Cr5 roll.Particularly suitable for rolling fastly, rolling thin strip and large deformation resistance of the six-roller mill.
