Abstract

The paper focuses on the production process of clean steel combining with the production practice of Ansteel, and analyses the measures to improve the quality control of clean steel from two aspects: the selection of refractory materials and the tundish metallurgy. Practice has proved that the appropriate choice of refractory materials of refining equipment and reasonable use of tundish metallurgy, taking in the tundish dam, argon blowing, iron powder injection, adding the double slag and other measures which can reduce the metal inclusions below 1 m steel and will effectively control impurity elements in steel (H, N, S, P, O) <80ppm.
