Development and Application of High Efficient Efficient Blowing Technology in Large Converter

摘要

Increasing oxygen intensity is an efficient measure because it can reduce the blowing time. In order to resolve the problem that the steelmaking production capacity was shortage when No.4 BF went into operation and the volume of BF was enlarged, the production capacity of steelmaking must be increased at Baosteel. Therefore, the research on increasing oxygen intensity and expanding steelmaking production capacity was done in 300t converters at Baosteel.
