High speed bar precision rolling mill roll ring

Introduction to the Roll Ring of High Speed Bar Precision Rolling Stand

Product specifications: 150-350

Material: High performance high-speed steel

Material code: HBWr08

This series of materials is a new type of material developed by our company for the roll rings of high-speed bar precision rolling frames. The hardness is HSD85-90. The hardness difference on the roller surface is ≤ 3HSD, the hardness drop is ≤ 2HSD, and the single grinding amount is small. This material has high wear resistance and impact toughness under thermal load, so the product not only has high wear resistance, but also has extremely strong impact resistance, especially when high-speed rolling large specification bars with a diameter of 18 or above, and is not prone to blockages and ring explosions. 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 single pass steel amount of high-speed steel roller rings can reach more than 60% of that of hard alloy roller rings, but the price of a single piece is less than one-third of that of hard alloy roller rings, which has a very high cost performance advantage. A precision rolling stand suitable for high-speed bars.
