A process for hot topping by electro-slag-remelting in which before or before and during hot-topping a portion of the liquid remelting slag in the mold is removed in order to achieve a hot topping of the ingot under a reduced amount of slag.

Process for hot topping by electro-slag-remelting

An apparatus for treating metal melts during continuous casting, wherein the teeming metal is enclosed to a point below the surface of the metal pool in the continuous casting mold to avoid contact with the ambient atmosphere and the surface of the pool is covered with a layer of slag. Small volumes of purging gas are introduced in bubble form into the metal melt at the location where such metal melt begins to form a teeming jet.
