Single stand reversible 4 high cold rolling mill

Single stand reversible 4 high cold rolling mill adopts the most advanced 4 high cold rolling technology. It adopts AGC press down control and has shape control methods of press down tilting, work roll bending. Single stand reversible 4 high cold rolling mill is widely used in industries of carbon steel, stainless steel and other metals. It features with matured technology, easy operation and low investment, etc.

The purpose and characteristics of 4 high cold rolling mill

1) Suitable for general carbon steel, stainless steel, special steel strip rolling;

2) Press down mode: there are two control modes: ordinary electric press down and AGC hydraulic press down;

2) Transmission mode: two transmission modes including work roll and support roll are optional;

3) The work roll bending device can be configured, which can quickly adjust the crown of the roll, change the contact pressure distribution between the rolls, and achieve the purpose of controlling the shape of the plate;

4) The whole machine has simple structure, convenient maintenance and operation, and less investment;

5) The AGC has high control precision, which is especially suitable for the production of high-precision cold rolled strip.

The composition of 4 high cold rolling mill

This 4 high cold rolling unit is composed of 4-high mill, right tension coiler, left tension coiler, roll changing devices, electric control system and other auxiliary equipment.

Line process of 4 high cold rolling mill

Front coiler ( with coil car) → front device → four -roller mill → rear device → rear coiler (with coil car). As needed, payoff roll can be configured, and head straightening machine and other equipment can be configured.
