Bearings for Rolling mill Rolls – IspatGuru
17/5/2017· Roll bearings are to meet the basic need of the rolling mill which is the smooth rolling of the steel products. They are friction reducing devices which provide support to the rolls for effective rolling with minimum of energy loss. The bearings are designed to withstand high rolling loads, heavy shocks, varying speeds, and high temperatures.
GENERAL ASPECTS OF ROLL COOLING FOR HOT & COLD ROLLING MILLS
As cold rolling of steel requires a lubricant in order to fulfil the lubriion role, oil is necessary. Hence, water-oil mixtures are used with a percentage of oil in water of approx. 5%. In most cases emulsions are the common coolants for cold rolling, where the oil and
