Abstract
In horizontal continuous casting, the casting proceeds step-by-step with the forming strand being intermittently pulled from the mold. The strand forms with a skin with a melt inside of the skin and this melt is stirred by a magnetic stirrer on the outside of the mold. This forms a thin wall in the skin at that location, forming a breaking location or point where the skin pulls apart each time the strand is pulled forwardly. The mold is continuously fed with melt and the skin's strand reforms or welds together at the strand break.
Claims3
A method for horizontal continuous casting comprising a succession of steps each comprising filling a horizontal continuous casting mold with a melt and allowing time for the mold to form in it a length of strand having a solid skin containing melt, and thereafter pulling the length forwardly partially from the mold while flowing additional melt into the mold so as to form a following length of said strand having its skin welded to the trailing end of the skin of the first length, and successively repeating said steps and forming additional lengths until step-by-step a desired length of casting is obtained;
- wherein the improvement comprises step of inductively stirring the melt longitudinally in the mold at a location between the ends of the mold so that the skin thins at that location and breaks apart during the pulling of the lengths of strand from the mold.
