efficiency of heat transfer(As melting proceeds the efficiency of heat transfer to the scrap and bath drops off and more heat is radiated from the arc to the sidewalls. 随着熔炼的进行,对废钢和熔池的传热效率下降,电弧辐射热更多地传向炉墙。)
breakout probability(The breakout probability is inversely proportional to the minimum shell thickness at the mold exit and is directly proportional to the temperature of liquid steel. 漏钢概率与结晶器出口处最低坯壳厚度成反比,与钢水温度成正比。)
rate of decarburization(The rate of decarburization as a function of oxygen (available from the lance as well as from the ore) must be known to determine the duration of the blow, so that the heat turns down at the desired carbon level. 脱碳速率作为氧气(包括氧枪供氧和矿石含氧)用量的函数必须为已知条件,以便确定吹炼时间,这样才能在达到预定含碳量时停炉。)
wind rate(The modem blast furnace with working volume of 3000 m³ is operated with wind rate of 6800 Nm³/ min and hot-blast temperature of 1086°C 这座工作容积 3000m³ 的现代高炉,风量为 6800Nm³/ min, 热风温度为 1086°C。)
