  • Friction and Surface Microstructure in Steel Cold Rolling

    Cold rolling lubrication trials were carried out on a high-speed reversing pilot mill. With low-alloy hot-rolled steel, significant differences were found in friction and strip cleanliness between three different emulsions, comparable to the performance on a production mill. Moreover, the trials show that the coefficient of friction clearly decreases as mill speeds increase. The corresponding

  • Cold Rolling process overview EngineeringClicks

    The cold rolling mill is usually fitted with thickness gauges that check the steel as it comes out of the rollers. Reversing mills are designed so that the steel can be reversed and pushed back through the rollers which are brought closer together each time until the desired thickness is achieved. Multi-stand mills have three to six pairs of rollers in a series, each pre-set to reduce the
