宝钢一期焦炉推焦车平煤系统故障原因分析及其措施

Faults Cause Analysis and Countermeasures of Coke-Thruster Smoothing-Coal System for the First Coke Oven of Baosteel

在宝钢一期焦炉大修重建后,推焦车多次出现推焦车平煤系统故障,造成平煤系统动力回路烧损,进而造成平煤杆无法正常退回烧损,严重影响大型焦炉正常生产,选择合适的平煤系统动力控制回路及其控制策略,对大型焦炉生产稳定运行具有重要意义。

Repeatedly occurring faults of the smoothing-coal system of cake-thruster after the Baosteel’s first coke oven was rebuilt causes the burning loss for power circuit and smoothing-coal shaft of the smoothing-coal system, and undesirable consequences for the large-scale coke oven production. Choosing appropriate power control circuit and control strategy for coke-thruster smoothing-coal system has an important significance for stable production of the large-scale coke oven.
