前言冶金喷粉技术,最初用来向转炉内顶喷石灰粉精炼高磷铁水。由于这种冶炼工艺只要求将石灰粉混同氧气一道,按事先规定的时间吹入熔池表面。因此对喷吹的稳定性及喷速的可控性,均没有提出明确的要求。随着氧气底吹转炉问世,要求石灰粉由下吹入熔池内部,发生上浮过程传输反应,来达到
Preface Metallurgical dusting technology was originally used to refine high phosphorus hot metal to the top of the converter. Because this smelting process only requires the lime powder mixed with oxygen along a predetermined time into the pool surface. Therefore, the stability of the injection and the controllability of spray speed, did not put forward a clear requirement. With the advent of oxygen at the end of the converter, the lime powder required from the bottom blown into the pool, the transfer reaction occurred in the floating process to achieve
