Abstract
A method of, and apparatus for, starting-up the casting of a strand during continuous casting, wherein molten metal, typically steel, is teemed through a bottom pouring outlet or opening of a tundish at a throughflow rate essentially determined by the dimensions of the pouring opening, into a continuous casting mold. By means of the dummy bar head of a dummy bar there is formed a connection between the dummy bar and the solidified strand forming in the continuous casting mold and after reaching a predetermined bath level in the mold the strand is withdrawn. According to the invention the throughflow rate is maintained smaller during a predetermined time span between the beginning of teeming the metal into the continuous casting mold and reaching the predetermined bath level by melting a tubular-shaped meltable body which has been introduced into the pouring opening, and the melting time of the meltable body is accommodated to such predetermined time span by dimensioning and/or selecting the material of such meltable body.
