Abstract

PURPOSE: To obtain the slab free from any rough surface and pinholes at the pressing by continuously casting the molten steel which contains the respectively specified amounts of C, P, S, Si and Al and the rest Fe and unavoidable impurities and is limited at the Mn and free oxygen amounts, while imparting electromagnetic flow to its freezing interface.
CONSTITUTION: The steel which contains C; 0.02W0.15%, P≤0.025%, S≤0.02%, Si≤0.01% being too small to deoxidize and Al≤0.005%, as well as the rest Fe and unavoidable impurities and is controlled to Mn; 0.06W0.2% and free oxygen amount 70W250ppm is prepared. Next, this molten metal is continuously cast while it is being given with electromagnetic flow with the velocity of the electromagnetic flow being controlled at about 0.1W1m/sec., whereby the weak deoxidized steel slab free from any pinhole is produced.
