  • Process for the continuous cooling and solidification of metal oxides by continuous casting
    Patent number: 4937022
    Abstract: To obtain from a product melt a product strip of uniform gage in the nip between two rotating rolls in a continuous cooling and solidifying of metal oxides by cotinuous casting, the gage of the nip, which is preset by the respective product strip, is measured between the rolls. One of the rolls is prestressed against the other by a force. The deviation of the measured gage from a set value is determined and the roll speed is regulated by means of this deviation.
