high speed steel rolls for bar rolling mills and cold strip mills

HSS rolls are mainly used as the work rolls in the hot strip mills and the finishing stands of bar mills; rings of the universal section mills and finishing stands of the high speed bar mills and so on.

1. Features: The Shell of Centrifugal casting High Speed Steel roll is a high carbon alloy steel containing Cr, Mo, W,V and Nb. The Microstructure consists of complex carbides embedded in a tempered martensitic martrix. Control of the carbon and a complex heat treatment allows the optimization of wear resistance, thermal fatigue resistance and oxide film formation, whilst maintaining low residual stress values.

2. Chemical composition for High speed steel rolls

our company successfully researched and developed high-speed steel roll. Through our continuous improvement and development of process flow, our high-speed steel roll has been widely used in finishing rolling mill of bar and wire rolling production line, especially for stand of K1, K2, K4, K5, showing good wear resistance and thermal cracking resistance performance. The average rolling capacity is higher than that of bainite roll of 3-5 times. The quality of our high speed steel rolls were highly praised by our customers at home and abroad.
