介绍了首钢长钢公司8号高炉鼓风机的主要系统结构及工作原理并结合它在实际运行当中存在的具体问题,根据工艺要求进行分析,从鼓风机的主电机启动、静叶角度控制、保护系统状况等方面提出了合理的优化方案。调试运行后证明:优化后的鼓风机避免了差动保护的误动作,并可准确掌握执行机构的动作,保护系统更加直观化,从而运行更加稳定、安全,运行成本降低10%,同时还减少了人力输入。
This paper introduces the main system structure and working principle of No.8 blast furnace blower in Shougang Changgang Company. Combining with the specific problems that exist in the actual operation, according to the technical requirements, the main blower from the start of the motor, the stator blade angle control to protect the system status And other aspects of a reasonable optimization program. Proved after commissioning operation: The optimized blower avoids the malfunction of differential protection, accurately grasps the action of the actuator, and protects the system more intuitively so that the operation is more stable and safe, the running cost is reduced by 10%, and the cost is reduced Human input.
