Abstract
A process and an apparatus for continuously casting strands of unkilled or semi-killed steel having a product of [%C] .times. [%O] that is less than 0.002, preferably less than 0.0015 due to deoxidizing prior to casting, a carbon content of between 0.02 and 0.20%, an Al content not exceeding 0.01% and a Si content not exceeding 0.05%, wherein the steel is cast from a tundish through a casting tube that is immersed in the mould and flush gas is introduced into the casting tube and moved on together with the steel which leaves said casting tube via two lateral, upwardly inclined openings. The ascending gas bubbles are deflected by means of a guiding plate and move through a gap formed between said guiding plate and the walls of said mould, flushing out CO-bubbles forming at the front of solidification and thus providing for an edge zone that is free from blow-holes.
