采用水电比拟法对高炉下部渣铁通过焦层的速度分布进行了测定，并将测定结果与有限差分法的计算结果进行比较，结果表明，二者数值误差在５％以内。该法投资省，设备简单，测定准确度高。
The velocity distribution of the slag through the coke layer in the lower part of the blast furnace was measured by the method of hydropower comparison. The results of the determination were compared with those of the finite difference method. The results show that the error between the two values is within 5%. The method of investment in the province, the equipment is simple, high measurement accuracy.
