简要阐述了某钢厂钢水真空精炼插入管清渣装置系统的组成、功能、设计.经过现场使用表明,装置清渣耗时不到10min,定位精度波动在8mm～+10mm,清渣作业率大于98％,能够在每炉生产的间隙进行,解决了原来火焰清渣时间太长的问题,大大减轻了工人的劳动强度,同时提高了钢水真空精炼的作业率.该厂的成功经验对国内同行具有借鉴价值.%This essay briefly introduces the composition, function, design in a steel plant when the vacuum refining of the molten steel inserts the scarfing cinder device. By field use it shows that the positioning accuracy is in-8 mm ~ + 10mm fluctuation when the time-consuming of scarfing cinder is within about 10 min. It can be carried out in each of the production of the furnace when the operating rate of scarfing cinder is more than 98%. It solves the original problem that the scarfing cinder of the flame takes too long and greatly reduces the labor intensity of the workers. And at the same time, it improves the operating rate of the vacuum refining for the molten steel. The plant's successful experiences has great reference value for the domestic colleagues.
