  • Patent number: 5018569
    Abstract: A method for continuous casting of thin slab ingots with reduced thickness following immediately the casting particularly of steel under utilization of a mold which is open at the bottom and under further utilization of roller pairs arranged along the withdrawal path, at least some of them are driven and at least some of the rollers are hydraulically adjustable perpendicular from the path so as to act as ingot deforming rolls. The invention is further improved by determining the speed of driven rollers, and the pressure force of adjustable roller pairs acting against the ingot and providing feedback control for the speed and the force. Additionally, providing a master control action for the speed control such that a point of solidification is dynamically maintained in a particular geometric position as far as the passing ingot is concerned; and by limiting the adjustment of rollers as far as the gap between pairs of such rollers is concerned downstream from that point.

  • Patent number: 5004040
    Abstract: A method of continuously casting steel in which a melt is introduced through a movable immersion nozzle. The method includes the steps of controlling the start of the casting process in connection with the withdrawal of the casting by starting the withdrawal of the casting upon reaching a desired height of the surface of the steel in the mold, and driving the casting from the mold at a desired casting removal speed via a control element in a predetermined manner. Further, the method includes measuring the position of the bath level as it ascends in the mold during the continuous casting and adjusting the position of the immersion nozzle in relation to the ascending bath level from a first position to a desired operating position by changing the position of the distributor.
