Process and apparatus for the continuous strip casting of metals, especially steel

摘要

In such a process for the continuous strip casting of metals, the molten metal (1) is introduced in a regulated manner from a supply quantity into a crystallizer (4) and the cast strip or cast billet (5) is drawn out in a regulated manner with a thickness of 10 to 40 mm. In order, in the continuous casting of thin billets into the relatively narrow continuous-casting moulds for thin billets, to achieve a solidification which is as rapid and as uniform as possible over the cross-section of the thin billets, it is proposed that the molten metal (1) be introduced into the supply quantity with an overheating of between 3 and 10 DEG C, that this overheating energy first be discharged from the supply quantity, and that there be introduced into the crystallizer (4) molten metal (1) which has a total viscosity of the two-phase melt/crystal state of less than 300 Centipoises.
