By investigating the test results of smelting malleable iron with 3t / h cupola of two-row tuyeres at short interval We are sure that ways of energy saving are multimedia under present conditions .

我们研究了3t/h两排短间距风口 冲天炉熔炼可锻铸铁的 试验结果，认为 冲天 炉的节能途径是多方面的。

The melting test of self - fluxed foundry formed coke was done in a 3 ~ 5 t / h industrial cupola .

用自熔性铸造型焦在3～5t/h工业 冲天 炉上进行的熔炼 试验 结果表明：这种型焦具有较明显的抑制 铁水 增硫的效果；

The results of high-speed hest analysis test before cupola are transferred to upper-computer and being automatically carried out for optimum burden computation .

炉前热分析快速 检测的结果传输给上位机，然后它自动进行最优化配料计算。
