This is a High speed steel rolling mill with low alloy content, so its price is cheaper than ordinary High speed steel rolling mills. This kind of kincof High speed steel rolling mill is always used for longitudinal cutting frames and frames before steel bar longitudinal cutting and wire milling. It reduces the chance of rolling blocks falling off. HBLA-HSS rolling mill has good wear resistance, thermal hardness, and thermal fatigue resistance.
