ABSTRACT:
Method for the continuous casting of high-carbon steels to produce thin slabs, these steels being characterised by a content of carbon greater than 0.50%, in which method the taper of the mould at least in its first segment having to be between 1.5% and 4% per meter, the frequency of oscillation of the mould being between 180 and 350 oscillations per minute with a travel upwards and downwards of about .+-.5 to 9 mm., with a total travel of 10 to 18 mm., the cooling in the primary cooling period being very intense, the times of the transient state of start-up of the casting being reduced by 1/3 to 1/4 as compared to the normal times of the transient state of start-up.
