Hot-rolled coil uncoiling-slitting-leveling-cut-to-
length-cutting-stacking combined production line
Performance and features:
This combined production line consists of uncoiler, feeder, pinch,
pre -leveler, scrap shear, Exchanged double slitter, scrap coiler,
fine leveler, shear, stacker, uncoiler, etc. it is used for cutting
steel coil into required width and length so as to produce material
for the manufacturing of steel structure, H beam, automobile beam,
pipe welding, cold forming, punching, etc.
The slitting line PLC control ,human-machine interface, according to a high degree of
automation ,simple operation and reliable.
It can be used to process metal coils of stainless steel, carbon
steel, iron, aluminum, galvanized tape, copper and other materials.
It is widely used in welding pipe, automobile, watch, metal
building materials, industrial plant and other fields.
