短语

1
介绍了设计原则、实现途径和极限真空估算。
The design principle, the way to carry out and estimation of limited vacuum were introduced.
2
环境温度较高时，油温升高，粘度下降，饱和蒸汽增大，会引起极限真空上升，应加强通风散热。
Higher temperature, oil temperature increase, decrease viscosity, steam increased, the limit will cause a vacuum up, we should strengthen the ventilation cooling.
3
真空抽气系统抽气性能的好坏直接影响RH-KTB精炼的脱气、脱碳、脱氮的效果，极限真空度高低决定了钢水最终的气体含量。
Vacuum extraction system of extraction performance affects behavior of degassing , decarburization, denitriding and so on in RH_KTB refining process.
