One kind of cold and shortened process unit

One kind of cold shortened process, comprising the steps of: unwinding a coil unwinding machine. The head and tail of the coil straightening process using straightening machine. Hydraulic shears cut the strip failed. Welding sheared head and tail of the strip welder. Strip looper via the inlet, enters the no-phosphorus acid unit. After the strip inlet Zhang Li roller mill through the phosphorus enters the rolling unit continuous rolling. Strip from the rolling unit successively rolled into the outlet looper with the outlet unit by washing and drying Zhang Li roller mill. This cold rolling process, since the hot-rolled material strip phosphorus acid and phosphorus-free technology, the rolled strip using strong large reduction mill, such as eighteen rolling mill, a rolling process to make the ordinary four or six rollers roll mill requires four to six stand continuous rolling reduction amount is completed, the completed racks 2-3. This rolling process, small footprint, low investment, environmental protection and energy-saving and pollution-free.
