Based on the research, founded on existing production conditions, production capability and technical natures of KISC, especially its own development requirements, linked with the development trend of the iron and steel industry, fully considering the continuity of equipment upgrade and technical optimization of KISC, guided under principles of validity and benefit, the writer analyses and argues that in current conditions. KISC shall not adopt the hot metal pretreatment of desiliconization, dephosphorization and desulphurization, but the end-point converter process to improve the dephosphorization effect. But according to the development plan of KISC, with its scale development, upgradeof equipment and technical conditions and implementation of a plan to use high-phosphorus ironstone, its more suitable to adopt the converter-shaped pretreatment of desiliconization, dephosphorization and desulphurization.

在此研究基础上，立足昆钢当前生产条件、生产能力和工艺特点，特别是昆钢自身发展需要，结合钢铁工业发展趋势，充分考虑昆钢现行装备改造和工艺优化的延续性，以有效性和经济性原则为指导，分析讨论了在昆钢当前条件下，不适宜采用铁水&三脱&预处理工艺，而宜考虑采用转炉复吹技术以达到改善转炉吹炼过程脱磷效果的目的；而根据昆钢的发展规划，随着昆钢的规模化发展，生产装备及工艺条件的更新改善及利用高磷铁矿计划的实施，则适宜采用转炉型&三脱&预处理技术。
