Forged rolls are manufactured by making holes in the center for the purpose of heat treatment and inspection purposes. The forged rolls(also known as rolling mill rolls or forged mill rolls) are primarily specified for work rolls, back up rolls, auxiliary rolls and special rolls. Forged rolls, commonly known as regular steel rolls, comprises 0.85 C, 0.30 Mn, 0.30 Si, 1.75 Cr, and 0.10 V. A certain percentage of Mo may be added to the basic composition and the chromium content varies to obtain specific characteristics. Forged rolls are primarily used in rolling mills, steel rolling mills, rolling mill machines for different types of metalwork processes. That is why the forged rolls are also called as rolling mill forged rolls, forged mill rolls, forged rolling mill rolls, rolling mill machne forged rolls, rolling mill rolls and mill rolls.
The proper hardness of the forged roll is essential which varies depending on the specific application and is developed with the cooperation of mill operators. To achieve higher hardness, forged mill rolls are treated are treated with heat and can be processed to lower values as well. Owing to their high hardness, hardened steel rolls are carefully handled while shipping, storage, mill service, etc.
The forged rolls are primarily used for rolling various metal sheets in the form of coiled sheet and strip. Cold rolling involves extremely high pressures and forged rolls have excellent strength, quality and wear resistance for cold rolling operations. Also, forged rolls are preferred in nonferrous hot mills over iron rolls due to their higher bending strength and resistance to metal pickup. |
