Latest company news about Effect of cold rolling mill cooling and lubrication systems for cold-rolled products

Cold rolling mill rolls through the metal rolled into a certain shape. Cold rolling mill in the rolling process, roll-to-metal pressing, the roll will be the phenomenon of elevated temperature, if the temperature rises to a certain extent, it will cause metal internal structural changes, thus changing the properties of the metal. So the rolling process in the cold rolling mill rolls for cooling treatment, in order to ensure conformity of the finished product.

 

Cold rolling mill lubrication system is also very important aspect, two axle boxes, roller bearing boxes and other rotating parts are needed lubrication to be adequately lubricated before the equipment can be more stable operation, in order to increase the life of the equipment; cold roll in the running also needs to be lubricated with water lubrication, emulsion lubrication oil, palm oil lubrication, different lubrication can also affect the size of the finished product common lubrication.

 

Water lubrication cooling is the most common way, is also the most cost way to save, through the pipes of the cooling roll continuous loop, so that the cold rolling mill rolls maintained at a temperature within a certain range. But the lubricating effect is not very good, metal products, especially steel rust easily see the water after the impact of surface appearance; other parts of the water splashed on the device, for a long time also easy to rust.

 

Use cold rolling mill emulsion is a common way, by a certain proportion of the emulsion and water blending, lubrication and cooling performance is better than water. When the roll rolled metal by the action of the emulsion, the metal can be a good pass, and has good ductility, after rolling metal surface gloss, little error.

 

Palm oil is the best for a cold rolling mill for the coolant, because the price is higher, so many manufacturers will not choose. Palm oil has good lubrication and cooling, when the cold rolling mill rolls to work with metal contact, there will be the phenomenon of adhesive tape, the use of palm oil lubrication can reduce this phenomenon, and cooling than water and saponification was better. Such as cold-rolled flat steel machine, the size of the finished product requirements more stringent, the use of palm oil lubrication effect will be very good, rolled out flat finished surface finish, size error is small.
