Burden distribution is one of the key factors affecting the gas distribution in the blast furnace.
炉料分布是影响高炉内煤气流分布的决定性因素之一。Due to those reasons, a production optimization is required as well as permanent control of Charge and Calcine.
由于这些原因，生产最优化是必须对炉料和煅烧砂进行永久性的控制。A new formula of the burden distribution along circumference in bell-less top blast furnace with parallel hoppers is presented.
建立了新的无钟并罐式高炉周向炉料流量公式。A mathematical model for accurately predicting the burden distribution of blast furnace was developed.
为了精确预测高炉炉料分布，开发了高炉布料数学模型。Moreover, experiences and lessons in handling the abnormal conditions caused by instability of the burden after re-blowing are summarized.
总结了复风后的炉料波动导致炉况失常及处理的经验。When flux is removed from charge, the desulphurization of gas increases, but sulphurization of iron ore has few changes.
炉料取消熔剂后煤气脱硫增加，而矿石吸硫量变化不大。In the meanwhile the furnace charge and products are computed and effects of change in scrap ratio on pro. . .
同时，还进行了炉料和产物的计算，分析了改变废钢比对生产的影响。foundry Adjust the burden distribution and maintain the good gas flow and thermal contact, Keep the hot blast has appropriate condition.
调节炉料分布及保持其与热煤气流的良好接触；保持高炉整体有合适的热状态。In the iron-smelting furnace the charges will finally produce two kind of liquid: molten iron and cinder.
炼铁高炉内炉料，最终产生两个液相：铁水和炉渣。
