Seamless Steel Pipe Rolling Mill Roll Ring
Product Specifications: °200-°650
Material: High Performance High Speed Steel(HSS)
This series of materials is a new type of material developed by our company for reducing the diameter of roll rings in seamless steel pipe production lines. The roll surface hardness is HSD80-86, and the hardness drop/10mm is ≤3HSD.The single grinding amount is small, and it can be used for 6-8 cycles. The total steel passing capacity of each group of roll rings can reach 3-4 times that of ductile iron roll rings, which has a high cost performance advantage.
This material has high wear resistance and impact toughness under thermal load, and the pas shape hardly changes during the rolling process. it can effectively control the size of the steel pipe and improve the surface quality of the steel pipe. The frequency of slot changing is low, effectively improving the operation rate, reducing faults and energy consumption, and reducing the labor intensity of workers. At the same time, there will be no phenomenon of falling blocks or exploding rings, CNC lathes can be used for proessing, which has high processing efficiency and low cost and is conducive to reducing the amount of backup rollers.
