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.
