The mill stand is the large size and weight part of the whole mill stand, and its weight accounts for 45~50% of the whole work stand.  All rolling force and horizontal tension, inertia impact and balance force in roll balancing device are borne by the frame.  The deformation of the frame directly affects the dimensional accuracy of the rolled piece, so the frame must have enough strength and stiffness, and the structure is inclined to disassemble and ring roll.  

Processing advantages  

1. According to the different types of rolling mill, we can customize closed frame, open frame, welding frame and combination frame to meet the needs of customers.  

2. For the modern rolling mill, for the convenience of roll change, the unique design is adopted for the forward cast steel. The bending cylinder is placed on the frame, and additional supports are added on the inside of the frame.  

3, the forward cast steel adopts special cast steel material, the cast mill stand has better performance, impact resistance and wear resistance are greatly enhanced, and the service life of the mill stand is improved.  

4, Qianjin cast steel can produce all kinds of crusher frame, cone crusher, impact crusher, jaw crusher and other crusher frame casting, can also be customized according to the drawings for enterprises.  

5, the forward cast steel adopts high strength steel, and is optimized for the operation characteristics of the crusher, so that the impact resistance and wear resistance of the frame is greatly enhanced, and the service life is prolonged.  

6, Qianjin cast steel can provide a full set of product solutions to meet the professional and personalized product needs of customers.  

The process flow  

According to customer requirements, qianjin cast steel chooses appropriate wood mold for modeling design, adopts CAE simulation casting of Hua Zhu before casting, strictly in accordance with the process of wood mold -- modeling -- pouring -- heat preservation -- pit sand removal -- heat treatment -- roughing and finishing -- packing and shipping, casting high quality rolling mill stand
