1.Brief Introducion Beijing Yang Wang Li Xin Science & Technology Co. Ltd(YWLX) has
beenpursuing to develop cold rolling technologies. The 4-hi/6-hi
single stand reversing cold rolling mill developed by YWLX is a
kind of cold mill with high precision, high efficiency, high yield,
good flatness, energy conversation and less investment, which is
very suitable for middle and little rolling firms. The Mill has
been widely used in China Hydraulic servo positive/negative bending-roll system will be
installed on work rolls and intermediate rolls. There are
gaugemeter and speedmeter installed in mill for showing and testing
automatically. The shift of intermediate roll will be locked with mechanical or hydraulic mode.
Hydraulic screw-down and automatic gauge control will be provided. 2.Technical Specification Input materials: carbon steel, low alloy steel, stainless steel
etc. Thickness of input material: 1.5-4.0mm Thickness of finishing product: 0.15-2.0mm Width of Coil300-1300mm Outside Diameter900～2100mm Specific weight11～19kg/mm Rolling speed180-1000m/min 3.Technical feature: Using PLC automatic control DC/AC total digital control Using roll stage cooling controlled by manual or automation positive/negative bending-roll for work rolls and intermediate
rolls. Quick roll change for work rolls and intermediate rolls. Using closed-loop for rolling speed control, tension control Function of breaking strip protection and accident alarm.
