Single stand reversible four high precision stainless steel cold rolling mill
Single-stand reversible precision stainless steel four-high cold rolling mill is a cold rolling mill specially designed for the production of precision stainless steel strips by using advanced four-high cold rolling technology. The unit adopts hydraulic pressure and has automatic thickness control system, which has the characteristics of small thickness deviation and good plate shape.
Equipment use and characteristics of four high cold rolling mill
1) Suitable for general carbon steel, stainless steel, special steel strip rolling.
2) Two transmission methods: work roll and support roll.
3) Electric pressing and hydraulic pressing are two pressing methods.
3) It can be equipped with work roll bending equipment, which can quickly adjust the crown of the roll, change the contact pressure distribution between the rolls, and reach the intention of controlling the shape of the plate.
4) The whole machine has simple structure, convenient maintenance and operation, and less investment.
5) Four-high cold rolling mill equipment control precision is high, especially suitable for high precision cold rolling strip production.
