 Steel Tube Coil Mill Roller Bar Roller HSS Roll With Durable Perfomance For Hot Rolled Section Steel_Tube_Rebar_Sheet Steel

Roll (Roller) is tool or mould for plasticizing deformation metals. It is is one of the most important parts of the rolling mill  to determine the efficiency and quality of rolling products. The plastic deformation of the rolled piece occurs through the rotating roll, and products that meet the required shape and dimensional accuracy are rolled out. Other parts on the rolling mill are set up to install, support, adjust, replace the roll and guide the rolled piece to enter the roll correctly.

 

High-speed steel (HSS) rolls are advanced metallurgical products widely used in the modern steel industry for hot rolling applications. These rolls are known for their exceptional wear resistance, high-temperature hardness, and thermal fatigue resistance. Composed of alloy elements such as tungsten (W), molybdenum (Mo), vanadium (V), and chromium (Cr) and so on, HSS rolls exhibit superior durability and performance compared to traditional cast iron and cast steel rolls.

Product description

High-performance HSS Roll has high wear resistance and harden ability, especially the red hardness at high temperature, which makes high-performance high-speed steel more suitable for manufacturing rolls and roll rings.

Therefore, high-speed steel rolls are not only suitable for wire and bar mills, but also for plate and strip mills, and have achieved remarkable results.

Superior quality of roll not only to improve the rolling quality, but also help the plant reduce carbon emissions.
