Method for reducing total scrap steel smelting cost of Consteel electric furnace by using anthracite

The invention discloses a method for reducing total scrap steel smelting cost of a Consteel electric furnace through anthracite, belongs to the technical field of ferrous metallurgy, can solve the problem that the production cost of an existing Consteel electric furnace is high, and achieves optimization of the anthracite utilization rate by adding different granularities and different amounts of anthracite in different stages of the smelting process of the Consteel electric furnace and combining an oxygen supply curve. By utilizing the characteristics of low cost, high calorific value, low ash content and the like of anthracite, the molten steel quality is improved, and the production cost is reduced. 一种利用无烟煤降低Consteel电炉全废钢冶炼成本的方法，属于钢铁冶金技术领域，可解决现有Consteel电炉生产成本高的问题，本发明通过在Consteel电炉冶炼过程不同阶段配加不同粒度、不同量的无烟煤，结合供氧曲线，实现无烟煤利用率的最优化，利用无烟煤成本低，热值高，灰分低等特点，提高钢液质量，降低生产成本。
