Abstract according to the definition of clean steel, a great significance in establishing a clean steel manufacturing platform is clarified. The technical index of new production process of clean based on hot metal pretreatment is analyzed and compared with that of traditional process of taking secondary refining as main body. In traditional process, there are four basic contradictions such as resulfurization, dephosphorization in melting low carbon steel, deoxidization and inclusion control, and strong reducing refining, which have an influence on production cost and energy consumption. To solve there problems, a platform for manufacturing high-efficiency and low-cost clean steel should be established. The platform must focus on full hot metal pretreatment, less-slag smelting, high-carbon taping, vacuum carbon deoxidization and change of inclusion floating, and so on.
