Features
1) The electrical control adopts Siemens AC driver technology. The automation control adopts Siemens S7-400 series PLC product.
2)The electric drive and automation system of the mill takes safety protection measures of overload protection, strip cut-off protection, and emergency stop,etc. The mill is equipped with functions of strip tail automatic deceleration, accurate stop, rolling process parameters set. The coiler has the functions of loops number memory and strip length calculation. The mill production process chain and malfunction alarming adopts PLC controlled to realize the automation of production process and malfunction alarming.
3)Rolling line adjustment device adopts stepwise wedge adjustment to realize the fast adjustment of rolling line
4)The reducer as the heavy-load drive equipment for the coiler and the main rolling mill, its gear adopts hardened face gear (gear grinding).the bearings on the reducer of the coiler and main rolling mill adopts China quality bearings.
5)Full hydraulic Screwdown, hydraulic AGC control. It is equipped with the functions of constant roll gap control, constant pressure control, roll deviation correction, thickness precontrol, monitoring, etc.
6)Mail rolling motor drive: 500KW AC
Coiler motor: 500KW AC
It can realize the large tension rolling mode.
Max. tension: 8 T
Max. speed: 360 mpm
7)The bending roll of work roll: the bending roll can be controlled from single side
respectively. Rolls are equipped with subsection cooling and roll shapes adjustment.
8) Single-station roll changing carriage is adopted, which realizes the swift changing of work roll
9)the roll bearing adopts air-oil lubrication with high lubricating efficiency, which prolong the bearing life span, reduce the oil consumption, the pollution and the maintenance
