2-Hi Rolling Mill

2-Hi Rolling Mill is used to roll raw material thickness ≤ 4 mm, width ≥ 200 mm, made of plain carbon steel, low alloy steel, stainless steel and non-ferrous metal strip, used for roughing or roughing mill.

Equipment composition

This machine is 2-hi cold rolling mill (hot rolling mill), usually 3-5 stands continuous rolling, which consists of main unit, main motor, reducer, herringbone gear one machine, universal joint shaft, electric screw down gear and electric control etc.. The strength of the device, rigidity, and ensures the accuracy and stability of the mill. This equipment strength, rigidity, to ensure the accuracy and stability of the mill.

This machine is used to roll raw material thickness ≤ 4 mm, width ≥ 200 mm, made of plain carbon steel, low alloy steel, stainless steel and non-ferrous metal strip, used for roughing or roughing mill.

This machine is a two-roll cold rolling mill, which consists of main unit, main motor, and reducer. Herringbone gear seat, universal joint shaft, electric screw down the device, electronic control and other components. The equipment with high Intensity, good rigidity, and ensure the accuracy and stability of the mill.

 

The advantages of the production process are as follows:

1. High production efficiency, high degree of automation, low labor intensity;

2. Material surface without oxidation; finished product with high yield, low production costs, available specifications are flexible;

3. The strong continuity of production, production process short;

4. No acid cleaning rust, environmental protection, and energy saving;
