Based on the casting manufacture practice of steel slabs by CSP technology, the flow and the temperature fields of the funnel mould and the secondary cooling segment were simulated using the commercial code, CFX4. Compared with other physical investigations, the correlative data of the present simulation results are in good agreement with them. Therefore, a more comprehensive survey for metallurgy characteristic of the flow and the temperature fields in CSP continuous casting process can be achieved.

Decopperization in molten steel with FeSNa2S slag was investigated in the laboratory. It was found that with an increase in FeS content of the FeSNa2S slag, the decopperization ratio increased. The decopperization ratio could reach the maximum of 716% in hot metal. The decopperization ratio was closely related to the carbon content, and the higher the carbon content, the higher was the decopperization ratio. Sulphur addition was found in the process of decopperization, and the increase in sulphur content of molten steel was about 02%-042%. However, by adding 30%-50% of BaO to the FeSNa2S slag, the addition of sulfur content in molten steel could be reduced by about 50%. The finer slag system composition was FeS∶Na2S∶BaO=40∶20∶40.
