Research and Application of Remaining Slag and Double-slag Process in Converter
In this paper,the current issues of traditional double-slag process are analyzed,and then the final remaining slag and double-slag are studied.With the aspect of automatic steel-making control,combined with the properties of new process,the model of de-slag and remaining slag is established,and relevant information such as slag composition in the earlier stage is included in the model calculation,so as to optimize the thermal oxygen balance.The blowing and charging of the model under the new process is modified based on the performance during actual production.This increased the target rate of carbon and temperature at the converter's end point to over 95.6％,enhanced the automatic control capability of steel-making under the new process,and laid the groundwork for the steel-making plant's overall efficiency.
