底吹气体流量(The bottom blown gas results in improved mixing of the metal bath, the degree of bath mixing increasing with increasing bottom gas flow rate. 底吹气体可以改善金属熔池的混合底吹气体流量越大，熔池混和程度越高。)
冷却速度(The rate of cooling to some extent determines whether the cast iron is white or grey； the more rapid the cooling the greater the tendency to form a white iron. 冷却速度在一定程度上决定了铸铁是白口铸铁还是灰铸铁；冷却速度越快，形成白口铸铁的倾向就越大。)
脱碳速率(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。)
排料速度(The material flow control gate opens to predetermined positions for the various types of raw materials to control the rate of discharge. 对于不同类型的原料，料流控制阀打开到不同的预定位置，以便对卸料速度进行控制。)
热流速度(A gap between the mold and strand causes the local rate of heat flow to diminish dramatically. The extent of this gap depends on the shrinkage of the shell. 结晶器和铸坯间的间隙引起局部热流速度急剧下降。该间隙的大小取决于坯壳的收缩量。)
传质速度(【技】溶液中的物质在扩散过程中，单位时间内通过单位截面积物质的量。传质速率与扩散速度之间的关系是：单位截面积上的扩散速率即是传质速度。: Below a critical carbon content the rate of mass transfer is insufficient to react with all the injected oxygen. 低于临界含碳量时，传质速度不足以维持与喷人的全部氧进行反应。)
供氧速度(At high carbon contents the rate of mass transfer is high such that most of the FeO formed is reduced and the rate of decarburization is controlled by the rate of oxygen supply. 在含碳量较高的情况下，传质速度如此之快，以致所形成的大部分 FeO 被还原；而脱碳速度则受供氧强度的制约。)
