转炉冶炼高锰铁水生产工艺的研究

Study on the Technology of Converter Smelting High Manganese Molten Iron

本文介绍了转炉冶炼锰元素氧化与还原的热力学,通过生产数据分析了转炉终点碳、铁水锰含量、终点温度、渣量、终渣氧化性等对钢水残锰的影响,总结了高锰铁水对转炉留渣操作和脱硫效果的影响,制定了转炉冶炼操作和提高残锰的控制措施。

The converter smelting manganese oxidation and reduction of thermodynamic principle is intro-duced in this paper. Through the production data, we analyze BOF end-point carbon, manganese quantity in molten iron, BOF end point temperature, slag quantity and final slag oxidability, study the effects of the above factors on the molten steel residual manganese quantity, summary the in-fluence of high manganese molten iron on the BOF remaining slag operation and desulfurization, and formulate the converter smelting operation mode and the control measures to improve the residual manganese.
