炭粉球团在硅铁生产中的应用

The Application of Powdered Charcoal Pellet in Ferrosilicon Production

主要简述了硅铁生产原理及炭粉球团生产工艺,提出利用炭粉球团代替部分木炭做还原剂的理论依据,并在硅铁生产的试验过程中得到验证。结果表明:炭粉球团在冶炼硅铁技术上可行,且对硅铁质量无影响,同时降低了生产各项技术经济指标。

The ferrosilicon production principle and powdered charcoal pellet production process is briefly described, the theo- retical basis that the powdered charcoal pellet can be used to replace the partial charcoal as the reducing agent is referred, and it can be test- ed and verified during ferrosilicon production experiment. The results show that： using the powdered charcoal pellet in ferrosilicon smelting is technically feasible, it has no effect on ferrosilieon quality, and at the same time the cost of ferrosilicon production is reduced.
