In this paper, it is introducrd the pre-remained 240 mm × 240 mm section for 6# casting machine of Baotou Steel is commissioned as well as such technical parameters as the electromagnetic stirring of crystallizer of casting machine, final electromagnetic stirring, secondary cooling water, nozzle type and water pressure of nozzle are mainly regulated and controlled. During the commissioning period, the low, medium and high carbon steels such as Q195, Q235, 45# and SWRH82B were produced as well as the scab and cracks were not found on the surface of casting blank. The ratio of grades of 0 and 1 could reach 94% by sulphur print and macroscopic examination, so the quality control of casting blank is good and can meet rolling demand of Steel Rolling Plant.
