摘　　要：主要介绍马钢利用球团竖炉焙烧菱铁矿工业试验的情况。试验结果表明：将焙烧温度控制在1 050-1 100℃,焙烧矿的w（TFe）由42%左右提高到62%左右,w（S）由0.3%左右下降到0.04%左右,抗压强度由6 000 N/块下降到1 050 N/块左右,转鼓指数由90%左右下降到47%左右,基本可以满足高炉或转炉对块矿的技术要求。Industrial experiment was implemented on baking siderite by a pelletizing shaft furnace in MaSteel.The results show that the content of TFe was increased from about 42% to 62%,the content of S decreased from about 0.3% to 0.04%,compressive strength came down from about 6000N/piece to 1050N/piece,and tumbler index dropped from about 90% to 47%,but they can meet the demands of a blast furnace or a converter.
