The hollow steel roll is welded by the roll body and the shaft head or long shaft at both ends. The roll body is made of thick-walled seamless steel pipe, and the shaft head is welded by two sections of short shaft/long shaft and the ring. It is characterized by high hardness and good wear resistance, and can be used as deflector roll and pinch roll, etc. The hollow steel roll is mainly fabricated through the processes of welding, stress relief treatment, finishing and dynamic balance test. The products are widely used in strip cold-rolling lines, temper rolling lines, pickling lines, galvanizing lines, and color-coating line, etc.
