vacuum ladle

The mathematical simulation for the flow field in the vacuum chamber and ladle during RH degassing was carried out by the N S equation, k ε two equation turbulence model and two phases zone structure model.

应用N-S方程、k-ε双方程模型及两相区结构模型对RH真空室熔池和钢包内钢液流场进行数值计算，为进一步计算浓度场和温度场奠定了基础，并解释了一些工艺现象。

Based on the laboratory results the industrial test of deoxidation of molten steel was done on 150 t with ferroalloy containing barium ladle furnace and vacuum degassing equipment.

在实验室研究的基础上，用150tLF/VD精炼设备进行了含钡合金对钢液脱氧的工业试验研究。

The WPB spray-powder is a device for desulfuration which is used by the WG Corp., it is an equipment introduced from abroad and used in company with the RH vacuum de-gas equipment, it can make deeper desulfuration for the molten steel of the ladle.

WG公司炼钢生产所用WPB喷粉脱硫装置系从国外引进设备，与RH真空脱气设备配套使用，可对钢包内的钢水进行深脱硫处理。

The basis of ⅵ process is that the powder is injected into the ladle during RH vacuum degassing.

Ⅵ法的实质就是在RH真空脱气过程中进行钢包喷粉。
