4/6-Hi Reversing Cold Rolling Mill

Four/Six Hi finishing reversing cold rolling mills, as YWLXs maturedproducts, have been used in many Chinese steel firms. Especially, the Six Hi reversing precise cold rolling mill, supplied by YWLX,can roll not only carbon strip steel but also oriented/non-orientedsiliconstrip steeland stainless strip steel.

YWLXhas developed the series of 900mm, 1150mm and 1380mm width of Six Hi reversing cold rolling mill, which produce not only the carbon steel strip, but also silicon steel strip and stainless steel strip. When rolling carbon steel strip(SPHC), the thickness can be reduced from 3.0mm to 0.2mm by six rolling passes without any annealing in process. When rolling oriented/non-orientedsiliconstrip steel, Its thickness can be reduced from 0.63mm to 0.26mm by 23 rolling passes. The thickness tolerance and flatness has satisfied the technical requirements.
