摘要： A method of controlling a hot face temperature of a copper plate of a mold for continuous casting of steel with variable casting rates and including: providing a bypass line for connecting a mold water outlet with a mold water inlet for obtaining, at the mold water inlet a mixture of heated mold water and cooled mold water, which mixture is fed into the mold as a cooling water having a chageable temperature depending on casting conditions; providing, at the mold water outlet, a two-way valve connectable with the bypass line and a heat exchanger for cooling the heated mold water for distributing the heated mold water between the bypass line and the heat exchanger with; and control of the operation of the two-way valve in accordance with the exit water temperature to maintain a constant predetermined water temperature at the mold water outlet, whereby a constant hot face temperature is maintained.

摘要： A continuous caster is controlled by a method anticipating the liquidus temperature in the mold of the caster to prevent premature solidification. The temperature in the tundish is measured and based upon the tundish temperature and the resistance time of the molten metal in the tundish, an equivalent liquidus temperature window is defined and the speed of the continuous caster is controlled to maintain this window of operation of the tundish.
