Development and application of BRP technology in Baosteel
The background of the development of the BRP technology (Baosteel BOF Refining Process) is presented along with the experimental conditions and results. The relations between dephosphorization and basicity of slag, bottom blowing, temperature at end point are analyzed. The effects on dephosphorization of bottom blowing, total iron of slag and silicon content in hot metal are also considered. The performance results indicate that, in the de-P converter and the de-C converter respectively, the dephosphorization efficiency is over 84% and 64% with phosphorus contents below 0.014% and 0.005%. Steels that are difficult to elaborate, such as tire corded or X 65 pipeline steel with HIC-resistance benefit from the BRP technology in Baosteel.
