本文首先从喷粉对底吹转炉炼钢工艺和供料设备的意义进行了分析,然后介绍了马钢12吨氧气底吹转炉喷粉设备设计和试验中的一些情况,分析了料仓下料口堵塞的原因和克服的办法,并说明对充压罐下阀进行了两种结构型式的多次试验,从而对V形球阀的性能得出了结论。本文着重指出,气体输料依靠的不是气体的压力,而是气流的作用,还指出充压罐的下压对下料的影响甚微,这是与“压差法”输料理论相对立的新的论点,可供大家参考和讨论。
This paper first analyzes the significance of dusting to the bottom blowing converter steelmaking process and feeding equipment, and then introduces some conditions in the design and testing of Masteel 12-ton oxygen bottom blowing converter powder spraying equipment, The reason of the mouth blockage and the way to overcome it, and the two tests on the structure of the under-pressure valve of the autoclave were described. The conclusion of the performance of V-shaped ball valve was concluded. This paper emphasizes that gas delivery relies not on the pressure of gas but on the effect of gas flow. It is also pointed out that the downward pressure of the pressurized tank has little effect on the feeding, which is the opposite of the theory of “differential pressure” New arguments for your reference and discussion.
