查询词典 degasser

Steelmaking Plant can be reduced to 20ppm by increasing argon flow of RH degasser and controlling vacuity According to the above results, the main efforts to develop IF steels have been made at No 3 Steelmaking Plant.

研究结果表明：钢水增碳主要在大包中发生，影响钢水增碳的主要因素是钢液与包壁接触面积与钢水体积之比，在高温下，耐火材料中CO的压力和钢水中Als的含量对钢水增碳也有一定的影响；钢水脱氧后将增硅，钢水的增硅量主要受大包渣的碱度、中包绝热板材料和中包保护渣碱度的影响；通过增大RH真空处理装置的氩气流量和控制真空度，能将三炼钢厂大包钢水的碳含量降到20ppm左右。

A modified homogeneous flow model was introduced to calculate the flow field in RH degasser,thus getting rid of some earlier methods that are unavailable to be generalized,such as reducing the computation region or presetting the distribution of gas volume fraction.

分别对有、无旋转磁场作用时的RH系统进行了模拟计算。模拟结果表明：流场和脱碳过程与现有文献中实验结果相符合；当旋转磁场作用后，磁感应强度为0.04 T时，初期脱碳速度比无旋流作用时增加了约15%，这是由于旋流增加了系统的搅拌能，提高了脱碳反应速率。

The mechanical pump is a direct drive rotary vane vacuum pump. It is used as a forepump for the diffusion pump, and to rough pump the degasser, the distillation, the distillate and the residue chambers.

机械真空泵直接驱动，为扩散泵预先抽取真空，也为了脱气，蒸馏，残留物收集器和蒸馏物收集器的抽取真空工作。

M/s. The following dimensionless relationships were obtained: Sh=2+0.073Re〓Sc〓〓〓 The desulphurization process by powder injection and blowing in RH refining of molten steel and its mechanism have been considered and analyzed. Based on the tworesistance mass transfer theory and the mass balance of sulphur in the system, a kinetic model for the process has been developed. The related parameters of the model have been reasonably determined. Modeling and calculations for the process by injecting and blowing the lime based powder flux under the assumed operating modes in a RH degasser of 300t capacity have been carried out using the model.
