Product Introduction

Cold rolling mills are used for cold rolling which is a basically metalworking process, which is used to cut down the size and thickness of a metal. This process is done while the metal is cold, unlike hot rolling or induction bending which is performed when the metal is hot. The cold rolling process will not only decrease the size of the metal that is being worked, such as steel or copper, intact it will also increase the strength and hardness of the metal.

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 thickness by a certain percentage until the final thickness is reached.

Usually each pass will reduce the thickness between 50 to 90%. Due to the high compression forces and friction, the temperature of each pass has the potential to reach as high as 250 °C. Therefore a cooling agent must be used to keep the rollers and metal cold and lubricated. Oil or water are usually used for this purpose.
