冶炼强度（I）是指单位体积高炉有效容积焦炭日消耗量，吨每立方米每天（t/(m3·d)），它是标志高炉作业强化程度的指标之一。 I=Qc/Vu Qc——焦炭日消耗量，Kg/d。 Vu——高炉有效容积，m3。
提高冶炼强度，应与降低焦比并举。
Both enhancing the smelting intensity and lowing the coke rate are necessary.
带有焦炭充填床的粉尘熔化炉，具有很高的冶炼强度。
The production intensity of the smelting furnace with a coke packed bed is very high.
单纯提高冶炼强度有可能导致一次能源浪费，使炉衬过早损坏。
Simple raise of smelting intensity may lead to energy wasting and fast lining damage.
