Cantilever Rolling Mill Roll Ring

Product specifications: °200-°550

Material: High performance high-speed steel(HSS)

This series of material is a new wear-resistant material developed by our company, which is mainly used for the cantilever rolling mill of the bar rolling production line. The surface hardness of the HSS roll ring is HSD 80-85, the hardness drop/10mm is≤3HSD, and the single grinding amount is small.

This mill roll ring can be used for 8-10 cycles, and the total steel passing amount can reach 4 times that of ductile iron roll rings, which is more than 25% higher than similar products in China and abroad. This material has high wear resistance under thermal load and can be used continuously for 8–12 hours before changing slots, effectively improving the operating rate, reducing faults and energy consumption, reducing the labor intensity of the workers, etc. At the same time, there will be no falling blocks, and the processing difficulty is low, making it suitable for the cantilever rolling mills of all precision bar rolling production lines.

It can adapt to rolling temperatures between 900 ℃ and 1050 ℃.
