The mill frame is a critical part of the rolling mill equipment, where the roller bearing seats and roller adjustment devices are mounted. Due to its complex shape and the heavy loads it bears, strict quality requirements are necessary; cast steel parts must be free of inclusions, shrinkage holes, porosity, and cracks. Casting is particularly challenging. The mill frame not only demands precise dimensions but also high mechanical properties from the cast steel components.

Processing Advantages:

1. Great Wall Machinery utilizes Huazhu CAE casting simulation software to simulate, analyze, and verify the initial process for the pavilion, optimizing the casting process. This ensures the casting mill pavilion has no shrinkage holes, no shrinkage porosity, and a dense structure, with excellent comprehensive mechanical properties.

2. Great Wall Machinery employs transformation treatment and bottom-blown argon technology in steel ladles to rigorously control the quality of molten steel, reducing the content of gases and harmful elements, enhancing the purity of the molten steel, thereby ensuring the quality of the mill frame.

3. Great Wall Machinery employs professional heat treatment methods, significantly enhancing the wear resistance and impact resistance of the rolling mill frame, thereby extending its service life.

4. Great Wall Machinery boasts robust casting capabilities for producing large quantities of parts like rolling mill bollards, with a short casting cycle and high output.

5. Great Wall Machinery utilizes high polymer structure in the production of rolling mill bollards, endowing the material with excellent impact resistance and significantly reducing wear.
