1. Description of goods:
Siemens electric control Automatic customized 4-Hi Steel Cold Rolling Mill

Cold rolling mill use a special cold forming process which is both cost-efficient and indispensable for many applications. It is used to improve roundness, stress homogeneity, and surface roughness of the tubes. The tolerance of finished tubes is about ±0.05mmCold rolling mill is devided into manual operate, automatic feeding and fully automatic and high speed type, the fully automatic type is high speed and continuous cold rolling type.

2. Introduction:
Due to different numbers of rollers, the metal coil cold rolling mill is divided into 2 Hi, 4 Hi, 6 Hi, and 12 Hi AGC.
This 4-Hi cold rolling mill, one of metal coil cold rolling mill, is made from good quality raw material. A four-high cold rolling mill has four rolls, two small and two large. The two small rolls are work rolls in contact with metal coil, and the two large ones are backup rolls which contact the back side of the small work rolls. At the same time, we are upgrading with the latest technological equipments when producing this cold rolling mill.
Mill working mode: continuous feeding without stopping; mill charging method: side loading; rolling mill stand form: closed stand; tube blank chuck feeding method: double screw clamp feeding method.

3. Features:

1. This 4-Hi cold rolling mill is a kind of portable type.
2. One stand and two frames are made from fabricated steel plates.
3. The number 2 Rolls on this cold rolling mill are made of chilled material.
4. It is equipped with heavy duty reduction gear.
5. The screw down system is manual.
Due to the differences of many aspects, such as input coils, output coils, max roiling forces, etc, the 4-Hi cold rolling mill is divided into different types.

4. Advantages:
1. The second type of cold rolling mill controls rolling speed and its tension.
2. The stable rolling is ensured.
3. This machinery greatly guarantee the safety.
