Mini Slitting line

I.Introduction of Stainless steel coil slitting line 
         slitting line is named coil slitting with workstations for uncoiling, slitting cut and rolling. It consists of feeding trolley, assisting support, decoiler, pincher, straightener, slitting cutter, edging machine, tensional machine, recoiler machine, and downloading equipment, hydraulic system and so on. The whole line is controlled by PLC with computer display. We mainly apply computer-control system of brands Mitsubishi, Yaskawa, Siemens, Baumueller, Delta, and Schneider. This line can help to improve efficiency, lower cost and ensure quality. ZHONGHENG has won wide market with its high performance and low price. The thickness of material can be from 0.15MM to 4MM, width from 600MM to 1500MM, quantity from 6 to 30 pieces, highest precision ±0.05MM and speed 60M/min. This line is applicable for processing of copper, aluminum, cold-reduced material, hot rolled material, silicon steel, and stainless steel and so on. 

Zhongheng provides customized slitting line solutions for all dimensions, from hot-rolled strip to thinnest, cold-rolled strip, from aluminum to stainless steel, in strip widths from 650 to 2,100 mm and strip thicknesses from 0.1 to 5 mm. Advanced and pioneering technologies are specially matched to the requirements of our customers. 

The high degree of automation in these slitting lines enables economical production, also of smaller lots, to reduce set-up times and to interface with coil packing and logistics.

Strand braking unit
