20-Hi Sendzimir Cold Rolling Mill

Feature and applications
Suitable for rolling high strength alloy steel, stainless steel, silicon steel and steels of extremely thin and high precision
Comparing with 4-Hi mill, 6-Hi mill and traditional 20-Hi mill with frame directly pressing down, It has the following notable features:
1. Whole cast frame, high rigid, rolling pressure radiate on the various section of the frame
2. Small working roll diameter, large pressure rate of rolling routes and total pressure rate
3. Pagoda shape roll assembly, structure of various section support back up roll, high rigid, less deformation and products with good plate shape and high precision
4. Small volume, light weight, it's only 1/2 of the other same type rolling mills
5. High precision, guarantee of manufacturing precision of 8 plum blossom shape channels on the frame is the key of the product.

Technical Flow

Charging saddle → Uncoiler → left tension roll → Feeding plate → front pinch roll → thickness gauge → vacuum degreasing → centering device → rolling mill → vacuum degreasing → thickness gauge → shear → right tension roll → post pinch roll → recoiler
