RH真空脱气过程的模拟研究

Simulation Study on RH Vacuum Degassing Process

本文对RH真空脱气过程进行了解析,建立了适合于RH真空脱气过程的物理模型及数学模型。模型能较好地反映 RH 真空脱气过程各主要元素及气相成分的变化规律。传质容量系数作为模型中的唯一可调参数,可表征 RH 真空脱气过程的传递特性及其操作特性。

By analyzing the process of RH vacuum degassing,the physical and mathematicalmodels for simulating the refining process have been developed.The models can express thephenomena of the main elements in melt and composition of gas in the process of RHoperation.The capacity coeffcient of mass transfer(A_SK)in the formulas of models is theonly adjustable parameter,it indicates the transfering characteristics and operating char-acteristics of RH vacuum degassing.
