4 Hi Skin Pass Mill: Precision Rolling Helps High Quality Steel Plate Production

The 4 hi skin pass mill is a finishing equipment used in metal rolling processes, mainly for the final processing of cold-rolled steel plates. Its core function is to improve the surface quality and shape of steel plates through mild rolling, and enhance mechanical properties such as yield strength and ductility.

The Main Functions of the 4 Hi Skin Pass Mill

1. Improve surface quality

By light pressing processing, the oxide layer, roughness, and defects on the surface of the strip steel are removed to obtain a smooth and uniform surface, meeting the surface quality requirements of high-end users.

2. Improve mechanical performance

Light pressing processing can eliminate the yield plateau generated during annealing, improve the yield strength and hardness of the strip steel, and enhance its formability.

3. Correct the shape defects of the board

Through precise rolling force and tension control, the 4 hi skin pass mill can effectively correct the shape defects of the strip steel, such as wavy edges, warping, etc., ensuring the flatness of the strip steel.

4. Oil coating treatment

During the processing, the equipment usually applies oil to the surface of the steel strip to prevent rusting during storage and transportation, while providing lubrication for subsequent processing.

The Application Advantages of the 4 Hi Skin Pass Mill  

1. High quality surface

The 4 hi skin pass mill can significantly improve the surface quality of strip steel, making it suitable for industries with extremely high surface requirements, such as automobiles, home appliances, etc.

2. Excellent formability

By eliminating the yield platform and increasing the yield strength, the strip steel processed by the 4 hi skin pass mill has better formability and is suitable for processing techniques such as deep drawing and stretching.

3. High precision shape control

The shape control function of the equipment ensures the flatness of the strip steel and meets the requirements of precision machining.

4. Efficient production

The 4 hi skin pass mill has a high level of automation and production efficiency, which can meet the needs of large-scale production.

Application Areas of the 4 Hi Skin Pass Mill

The strip steel processed by the 4 hi skin pass mill is widely used in the following fields:
