High speed wire pre precision rolling mill frame roll ring

Introduction to the Roll Ring of High Speed Wire Rod Pre precision Rolling Mill Stand

Product specifications: ° 150- ° 320

Material: High performance high-speed steel 

Material code: HBWr05

This series of materials is a new type of material developed by our company for the roll ring of the pre precision rolling mill frame for high-speed wire rods, with a hardness of HSD88-93. Uniformity 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, 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, it has good processing performance and can be processed with a CNC lathe, with high processing efficiency and can reduce the amount of backup rollers. The total amount of steel passing through each group of roller rings can reach over 70% of that of hard alloy roller rings, and the price is less than 40% of that of hard alloy roller rings, which has a very high cost performance advantage. Suitable for pre precision rolling of high-speed wire rods.
