全氧高炉炼铁——生铁粒化脱碳——电炉炼钢——水平连铸4种技术的组合,形成了一个适用于小型钢铁厂的生产流程。全氧高炉炼铁工艺全面提高了小高炉生产指标并实现了以煤粉为炼铁主要能源。脱碳粒铁——电炉炼钢解决了高炉生铁小型化炼钢的难题。精密水平连铸则简化了轧钢工序并减少钢坯加热煤气消耗。另一方面全氧高炉提供的高质量煤气为建立高效自备电厂创造了条件,这就使小型钢铁联合企业有可能应用这一合理组合达到完善的企业内部能量平衡。
Oxygen blast furnace ironmaking - pig iron granulated decarburization - EAF steel - horizontal continuous casting four kinds of technology portfolio, forming a suitable for small steel plant production processes. Oxygen blast furnace ironmaking process to raise the overall production index of small blast furnace and to achieve the coal as the main ironmaking energy. Decarburization iron - electric furnace steelmaking to solve the miniaturization of blast furnace pig iron steelmaking problems. Precision horizontal continuous casting simplifies the rolling process and reduces the heating gas consumption of the billet. On the other hand, the high-quality gas supplied by the whole oxygen blast furnace has created the conditions for establishing an efficient self-provided power plant. This makes it possible for the small steel conglomerate to use this reasonable combination to achieve a perfect internal energy balance within the enterprise.
