Abstract

Uses of Kazakhstan coal and coke in the steel industry are proposed: long-flame coal in the converter; carbonizing agents based on special coke; and coke in the carburization of steel. Technology for preheating of scrap in converters using sorted Shubarkol long-flame coal (Kazakhstan) is developed and introduced. Coal of the 13–25 mm size class gives the best results. This technology is recommended for converter shops at steel plants. The quality of special coke produced at AO Shubarkol Komir produced from low-ash, low-sulfur, and low-nitrogen long-flame coal is investigated. On that basis, it is proposed as a carbonizing agent. When using different classes of coke, improvement in the production process and in steel quality is predicted.

哈萨克斯坦长焦煤和特殊焦炭在钢铁工业中的应用

摘要

建议在钢铁工业中使用哈萨克斯坦的煤和焦炭：转炉中的长燃煤；基于特殊焦炭的碳化剂；和焦炭在钢的渗碳中。开发并引进了使用分选的Shubarkol长燃煤（哈萨克斯坦）对转炉中的废料进行预热的技术。尺寸为13–25毫米的煤可获得最佳效果。建议将该技术用于钢铁厂的转炉车间。研究了由低灰分，低硫和低氮长焰煤生产的AO Shubarkol Komir生产的特殊焦炭的质量。在此基础上，提出了作为碳化剂。当使用不同种类的焦炭时，可以预见生产工艺和钢质将得到改善。
