In view of the serious splashing problem in the 120 ton Ruhrstahl Heraeus (RH) refining process of a special steel company, a coupling model of volume of fluid + discrete phase model was established to study the influence of the vacuum pressure drop mode on the RH vacuum splashing. Three different pressure drop modes were simulated, and the splash situation was described by the fluctuation of the liquid level and the velocity field in the vacuum chamber in this model. The model predicted that the most serious splashing situation of liquid drops would happen at the early stage of vacuum treatment, which was consistent with that found in industrial production. The liquid level in the vacuum chamber maintained a low fluctuation at the late stage of the RH vacuum process. The vacuum pressure drop mode was closely relevant with the splashing situation. The splashing of liquid steel can be effectively improved by controlling the vacuum pressure drop mode, and it can be used in the industrial production situation.

Ruhrstahl Heraeus真空过程中钢滴的飞溅模拟

针对某特殊钢公司120吨鲁尔斯塔尔·贺利氏（RH）精炼工艺中严重的飞溅问题，建立了流体体积+离散相模型的耦合模型，研究了真空压降模式对RH的影响。真空飞溅。模拟了三种不同的压降模式，并通过该模型中液位的波动和真空室内的速度场来描述飞溅情况。该模型预测，最严重的液滴飞溅情况将发生在真空处理的早期，这与工业生产中发现的情况一致。在RH真空过程的后期，真空室中的液位保持较低的波动。真空压降模式与飞溅情况密切相关。
