With the feature of good surface quality,good surface finish,high precision,excellent product property,etc.Cold Rolled strip is widely used for Continuous hot galvanizing line(CGL)
Continuous hot galvanizing line(CGL)
Continuous hot galvanizing line(CGL)continuous plate of zinc or aluminum zinc coating on the surface of cold-rolled steel plate,increase the corrosion resistance of steel plate
Color coating line(CCL)is to coat the strip surface with organic,make the surface more colorful and further enhance the corrosion resistance of strip
Pickling line plays a key role before cold rolling,Its main function is to use mechanical and chemical function,remove the strip iron and dirt of the strip steel surface after hot rolling
