Abstract: A roller apron for a continuous casting installation, especially for casting steel strands, for supporting a partially solidified strand, which comprises a number of successive pairs of rolls which follow one another in the direction of travel of the strand. The bearings of at least one roll are arranged at a traverse or crosshead extending essentially parallel to the lengthwise axes of the rolls. The traverse can be applied against stops governing the format or cross-sectional thickness of the strand and coacting at both ends with pivotable levers articulated at the machine frame and at a movement device. The movement device comprises a power source interconnecting both of the pivotable levers.

Abstract: An apparatus for measuring the geometry of the hollow mold compartment of continuous casting molds comprising a measuring head displaceable essentially in the direction of its lengthwise axis and having three impact or contact elements arranged at a first side of the measuring head. The impact elements form a triangle which is parallel to the lengthwise axis of the measuring head. A first measuring feeler is arranged at this first side so as to bear against the neighboring mold wall and is perpendicular to the plane of the triangle and at least one resilient impact element is arranged at a second side of the measuring head opposite the first side and produces a force-vector directed away from the triangle at a right angle. A second measuring feeler is arranged at the second side of the measuring head coaxial to the first measuring feeler and bears against the opposite wall of the hollow mold compartment. Indicator elements operatively connected with the measuring feelers indicate the position thereof.
