摘要
为了解决钢包自开率低的问题,对唐钢一钢轧厂150t精炼钢包自开率影响因素进行了分析。通过选用合理的引流砂、改进加砂装置、提高上水口洁净度、缩短钢包盛钢时间等措施,使钢包自开率从原来的98.5%提高到目前的99.8%。
In order to solve the problem of low free-opening rate of ladle nozzle,the influence factors on free-opening rate of 150 tladle in the First Rolling Plant of Tangang were studied.By selecting reasonable ladle nozzle packing sand,improving sand adding device,improving the cleanliness of upper nozzle,shortening the residence time of liquid in ladle and other measures,the ladle free-opening rate is increased from original 98.5%to 99.8%at present.
