BL20-225 Type 20-high Reversing cold Rolling Mill
Suitable for rolling high strength alloy steel,stainless steel,silicon steel and steels of ex- tremely thin and high precision.
MAIN TECHNICAL PERFORMANCE
Nonminal diameter of working roll Back lining bearing diameter Strip width Min.product thickness Thickness precision
40mm 225mm ≤650mm 0.06~0.08mm ±0.002mm
FUNCTIONS & CHARACTERISTICS
Suitable for rolling high strength alloy steel,stainless steel,silicon steel and steels of ex- tremely thin and high precision.

 

Comparing with four-high cold mill,six-high cold mill and traditional 20-high cold rolling mill with frame directly pressing down,It has the following notable features:
• With whole cast frame,high rigid,rolling pressure radiate on the various section of the frame.
• With small working roll diameter,large pressure rate of rolling routes and total pressure rate.
• With 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.
• Small volume,light weight. It's only 1/2 of the other same type rolling machines.
• High precision,the guarantee of manufacturing precision of 8 plum blossom shape channels on the frame is the key of the product.
