PLC Automatic Control HR / CR Steel Coil Slitting Machine

Description
This slitting line is used for slitting raw material coils into strips. This machine can slit raw material coils into specific width. Our company has series of slitting lines, with thickness of 0.1-25mm and width up to 2500mm. The slitting line normally includes loading trolley, decoiler,guiding device (including lead roll, peleer table), coil head shear, centering and calibrating device, slitting machine, scrap rewinder, pre-distribution and tensioning machine, recoiler, and unloading trolley. The machine adopts PLC VF controlling system, DC driving for the slitting and recoiling, Touch screen operating and digital display. The production line is widely used for steel coil servcing for cold rolled steel, hot rolled steel, galvanized steel, stainless steel, etc.

Feature of the Machine

1. Double cone heavy duty decoiler, capacity up to 40 tons

2. DC driving for slitting and recoiling

3. Mitsubishi PLC controlling, VF speed control, touch screen operating
