莱钢炼钢厂LT电除尘控制的探讨

Discussion on Electrical Precipitator Control of LT Method in Steelmaking Plant of Laisteel

介绍了莱钢炼钢厂LT电除尘控制系统的工作原理、电气结构及控制方式,揭示出转炉吹炼状态与电除尘负载状态的关系。结合实际生产中所遇到的问题,就电除尘常见的短路故障和放电极故障的表现形式、产生原因及其影响进行了详细分析,并提出一些意见。

The paper describes the working principle,electrical structure and the control mode of the electrical precipitator of LT in Laisteel steelmaking plant.Meanwhile,it reveals the relation between the blowing statuses of the converter and the load statuses of the electrical precipitator.Based on the problems that have been encountered during production,the shortcut fault and discharging pol′s fault are analysed,and some opinions are put forward.
