Stainless steel 20-High cold rolling Mill

the 20-High cold rolling mill is suitable for cold Rolling high-strength steel materials such as stainless steel, silicon steel and carbon steel, and is the best choice for precision stainless steel strip Rolling.

the 20-High cold rolling mill has the advantages of high rolling thickness accuracy, good flatness, and excellent strip shape.

the 20-High cold rolling mill has a high level of Automation, saving labor costs and high efficiency.

for rolling stainless steel materials, the reduction Rate is above 90%, and the rolling speed is 700 m/min; the maximum reduction Rate for rolling carbon steel materials is above 95%, and the rolling speed Reaches 800 m/min. the rolling output thickness is as thin as 0.03 mm.

Main parameters

Maximum rolling speed:                      800 meters/minute

Minimum rolling thickness:                 0.03 mm

Maximum rolling width:                       1675 mm
