Pinch Roll Ring
Product specifications:°200-°500
Material: High performance high-speed steel(HSS)
This series of material is a new type of material developed by our company for the pinch roll rings of the high-speed steel (HSS) wire rods and bar rolling mills, with a hardness of HSD88-93. Unifomity of roller surface hardness ≤3HSD, hardness drop/10mm: ≤ 2HSD, single grinding amount (reduction): ≤0.8mm.
This material has high wear-resistance and impact toughness under thermal load, so the product not only has high wear resistance characteristic, but also is less prone to ring explosion in pre-precision rolling stands with larger material types and deformations than hard alloys. At the same time, CNC lathes can be used for processing, which has high processing efficiency and low cost and is conducive to reducing the amount of backup rollers, The total amount of steel passing through each group of roll rings can reach over 70% of that of hard alloy roll rings, and the price is less than 40% of that of harden alloy roller rings, which has a very high cost performance advantage, suitable for the high-speed steel (HSS) wire rods and bar rolling mills.
