<p>A steel sheet for continuous cast enameling which has highly excellent unsusceptibility to fishscaling and an enhanced hydrogen-trapping ability obtained by improving the ability to form voids in the steel sheet. The steel sheet contains, in terms of mass%, up to 0.010% C, 0.03-1.30% Mn, up to 0.100% Si, up to 0.030% Al, up to 0.0055% N, up to 0.035% P, up to 0.08% S, 0.005-0.085% O, and 0.0003-0.0250% B as steel components. Oxides which differ in boron or manganese concentration by mass are contained in the steel sheet, the oxides having not been united or having been united. The ratio of the maximum concentration to the minimum concentration thereof is regulated to 1.2 or higher. When the oxides have not been united, they are caused to be present so that the distance between the centers of the oxides differing in concentration is from 0.10 µm to 20 µm and the straight line connecting the centers of the two oxides has an angle which is within ±10° based on the rolling direction.</p> |
