ABSTRACT:
Apparatus and processes for use therewith are provided for the start-up of the continuous casting of strip metal, preferably steel, in which liquid metal is poured into a flared type continuous casting strip-shaped mold equipped with detector means for monitoring the instantaneous surface level of the liquid metal bath formed in the flared zone of the mold, and sensor means for sensing the presence of liquid in the core of the cast strip downstream of the mold, and means are further provided responsive to said detectors and sensor for controlling both the rate of pouring the liquid metal, and the start-up and rate of withdrawal of the cast strip to ensure the continuous presence of a liquid metal core in said cast strip downstream of said mold, for signalling when the distribution ports of the pouring tube become submerged, and for thereafter during casting maintaining a predetermined optimum operating surface level of said metal bath.
