本文阐述了竖炉含氧化镁碱性球团矿的实验室研究和工业试验。研究结果表明:1)用石灰石粉代替消石灰作球团矿的熔剂,生球的爆裂温度可以满足竖炉工艺的要求。2)含氧化镁碱性球团矿与酸性球团矿比较,冶金性能有了明显地改善,用它代替酸性球团矿进行高炉冶炼,燃料比和生铁含硅量大幅度下降,产量增加。 This article describes the laboratory research and industrial testing of shaft furnaces containing magnesium oxide alkaline pellets. The results show that: 1) Limestone powder instead of slaked lime as pellet flux, the ball burst temperature to meet the shaft furnace process requirements. 2) Compared with acidic pellets, the metallurgical properties of magnesia-containing alkaline pellets have been significantly improved. Instead of using acidic pellets for blast furnace smelting, the fuel ratio and the content of silicon in the pig iron have dropped drastically and the output has increased.
