CONVERTER STEELMAKING PROCESS |
摘要 |
<p>An improved converter steelmaking process that achieves a great increase in the refining capability of top-blown oxygen is provided. The process applies to an oxygen top-blowing converter that also permits bottom blowing of gas and it is characterized by supplying oxygen from a top-blowing lance and a bottom-blowing nozzle substantially throughout the refining operation, with 2 vol% to less than 17 vol% of a predetermined total oxygen flow rate being supplied from the bottom-blowing nozzle whereas the remaining part of oxygen is blown onto the surface of the hot metal from the top-blowing lance.</p> |
