FORGED STEEL ROLLS, SHAFT AND RINGS
These are carbon steel and alloy steel Rolls and are manufactured by pressing, pounding or squeezing metal under great pressure into high strength blanks by open die hot forgings. Preheating the metal to a desired temperature before it is worked normally performs the process hot.
Application:
Application of Forged Steel Rolls can be used only on Roughing Stand in all types of Hot Steel Rolling Mills.
Application: These Rings are used in finishing stands of TMT mill & Wire rods for extended life in applications where long rolling campaigns are required. Their extreme hardness makes them suitable for wire rods finishing blocks and some shaping applications.
