宝钢300t氧气顶吹转炉采用u—400过程控制计算机控制吹炼终点。开工以来,终点控制效果日益提高。1986年8月,终点同时命中率达到72.4％,一次吹炼率达到81.7％,转炉各项技术经济指标达到较好水平。概要阐述了终点控制模型和主要技术经济指标,并提出从1)原材料条件;2)最佳吹炼模式和标准化操作;3)氧枪喷头性能稳定;4)提高副枪测成率;5)提高吹炼技术水平等方面提高终点同时命中率。
Baosteel 300t oxygen top blown converter using u-400 process control computer-controlled blowing end point. Since the start of the end-point control effect is increasing. In August 1986, the end hit rate reached 72.4% at the same time, a blowing rate of 81.7%, the converter of various technical and economic indicators to a better level. Summarize the end point control model and the main technical and economic indicators, and propose from 1) the raw material conditions; 2) the best blowing mode and standardization operation; 3) lance nozzle performance and stability; 4) Improve the level of technology and other aspects of blowing improve the end hit rate at the same time.
