给出了铸造焦在冲天炉中的熔炼试验结果。结果表明：使用铸造焦比使用冶金焦的熔炼铁水温度平均提高５５℃－７０℃，铸件的机械性能明显提高，废品率显著降低。
The results of the melting test of the foundry coke in the cupola are given. The results show that the average temperature of molten iron melt increased from 55 ℃ to 70 ℃ using metallurgical coke. The mechanical properties of the castings were obviously improved and the rejection rate was significantly reduced.
