The basic laws of ballistic motion are used to calculate the following in coordinate form: the residence time of a metal droplet in slag with adsorbed nonmetal impurities (NMIs) with the inert gas blowing of liquid steel in a CC machine’s pony ladle. These data can be used to set the optimal speed of eliminating NMIs from the metal in the pony ladle at different gas consumption rates, as well as the plausible diameter of gas bubbles. The eliminations of the NMIs in the pony ladle using extended blowoff tuyeres were compared for efficiency during industrial tests. The NMI content was estimated by technique K4 under DIN 50602-1985. The theoretical calculation of the optimal inert gas consumption for the metal blowoff through an extended multichannel tuyere was made, the surpassing of which weakens the refining effect due to the slag capture in liquid melt.

小马钢包炼钢分析

弹道运动的基本定律用于以坐标形式计算以下内容：金属液滴在吸附了非金属杂质 (NMI) 的炉渣中的停留时间，以及在 CC 机的小钢包中向钢水吹入惰性气体。这些数据可用于设置在不同气体消耗率下从钢包金属中去除 NMI 的最佳速度，以及气泡的合理直径。在工业测试期间，比较了使用延长的吹气风口消除小钢包中 NMI 的效率。NMI 含量通过技术 K4 根据 DIN 50602-1985 估算。对通过扩展多通道风口吹出金属的最佳惰性气体消耗量进行了理论计算，
