新钢2500m3高炉经济炼铁的探索

摘要

Through the optimizing of burden contracture, it successfully implements a series of operation techniques, such as high top pressure, high blast temperature, economic coal injection, low silicon smelting, economic smelting in-tensity.Under the condition that the quality of material is decreasing, it obtains a better smelting result.%通过优化炉料结构，成功实施高顶压、高风温、经济喷煤、低硅冶炼、经济冶强实践等操作技术。在入炉料质量有所降低的条件下，取得了较好的冶炼效果。
