所谓操作氧压是指转炉氧枪输氧管路中,快速切断阀后测压点处的压力,其读数P_c在转炉操作室内的仪表屏上显示,其数值的大小由快速切断阀前的调压阀控制。确立操作氧压P_c与氧枪喷头入口断面上的氧压P_n之间的关系,也就是查明所述输氧管路的静压降△P,其用处有二:①在设计氧枪时,验算输氧管路的设计布置能否满足P_n的要求,以及确定调压阀的调节范围;②在生产中(即输氧管路布置和氧枪结
Oxygen operation refers to the so-called oxygen lance oxygen converter pipeline, the pressure quickly cut off the pressure at the pressure at the point, the reading P_c in the converter operating room instrument panel screen, the value of the size of the rapid cut-off valve before the pressure Valve control. Establish the relationship between oxygen pressure P_c and the oxygen pressure P_n on the inlet section of oxygen lance nozzle, that is, ascertain the static pressure drop △ P of the oxygen inlet pipe. There are two reasons for using it: ① When designing lance, Oxygen pipeline design and layout can meet the requirements of P_n, and to determine the regulatory range of pressure regulating valve; ② in the production (ie oxygen pipeline layout and oxygen gun knot
