此工艺又名吹炼搅拌复合工艺,即往钢水内深吹氧和其他气体,既达到了吹炼目的,又起到了搅拌作用,可说是避开了顶底吹之短而张扬了顶底吹之长,它较之碱性炉吹氧炼钢更进了一步。在碱性炉氧气顶吹炼钢过程中,化学电势、温度、金属流和熔渣流有局部的时间差。在底吹转炉中,采用底吹进行强力搅拌,可缩小它们的差。为达到此目的,采用了各种方法,如通过几个风口、被覆管、多孔插管进行底吹或侧吹氩、氮、氧、二氧化碳、碳化氢等,同
This process, also known as blowing mixing mixing process, that is, to the oxygen in the molten steel and other deep oxygen blowing, both to achieve the purpose of blowing, but also played a stirring effect, can be said to be avoided by the top and bottom of the blowing and publicity Top Blowing long, it is a step further than the basic furnace oxygen steel. During the basic furnace oxygen blowing, the chemical potential, the temperature, the metal flow and the slag flow have a local time difference. In the bottom blowing converter, the use of bottom blowing strong mixing, can narrow their difference. In order to achieve this, various methods have been adopted, such as blowing or side-blown argon, nitrogen, oxygen, carbon dioxide, hydrocarbon and the like by means of several tuyeres, covered tubes and porous cannulas
