Study on Inclusions of Low Carbon Steel Slabs Produced in Different Casting Stages
Through studying the inclusions of low carbon steel slabs produced in different casting stages, the results are dawn as follow. The reoxidation of liquid steel is very serious in casting starting,but the casting ending is not. Most of large-inclusions containe K or Na are found in the first and final slabs, which may relate to serious slag entrapment in the mould in the casting starting and ending. Many MgO-Al2O3 and Al2O3-CaO-SiO2-MgO inclusions suggest the serious entrapment of the tundish in the casting ending.
