竖炉配料自动化控制系统改造

针对山钢股份莱芜分公司炼铁厂8 m2竖炉配料设备自动化程度低、配料精度差等问题,通过实施技术改造,更新配料秤、变频器、振打电机、现场操作箱、控制电缆等设备,并对新设备和配料自动控制系统进行安装调试,实现了自动精确配料,提升了竖炉配料自动化水平,提高了球团矿的产量和质量,矿石成本由1 025元/t降为1 012元/t。

Reformation of Burden Automation Control System for the Shaft Furnace

Pointed at the problems of lower level of automation and burden accuracy in the shaft furnace, through the implementation of technological transformation, some facilities including batch scale, frequency converter, vibrating motor, operation box and control cable etc were updated. Furthermore, through installing and setting up the new equipment and the automation control system, accuracy automatic burdening was realized, the burden automation level was improved, the pellet quality and productivity were raised and the ore cost was reduced from 1 025 to 1 012 Yuan RMB per ton.
