  • Patent number: 7198092
    Abstract: A chill tube (1) having a double T-shaped inner and outer cross section in beam blank format is encased in a water-guiding jacket (12) adapted to its outer contour while forming a water gap (14). The wall thickness (D) of chill tube (1) in the rounded transition regions (2) from middle crosspieces (4), which face each other head to head and are drawn in towards longitudinal axis (3), to the neighboring crosswise positioned flanges (5) is dimensioned at least partially smaller than in the remaining wall sections (6, 7). The reduction in wall thickness is implemented by longitudinal hollow recesses (8). These recesses (8) extend only in the height range of the bath level. Into the cross sectional regions which are formed by the outer contour of chill tube (1) as well as the inner contour of water-guiding jacket (12), filler pieces (17) are incorporated, adapted to this cross section.

  • Patent number: 6942012
    Abstract: A chill tube (1) for the continuous casting of metals has a double T-shaped cross section in beam blank format. Inner contour (3) defining the cross section of the cast billet is cooled by cooling water, which is guided through cooling channels (4) in tube wall (2). Cooling channels (4) have a round cross section when manufactured. Inner contour (3) has rounded transitions (6) between wall sections (9) bordering a flange region (7) and a crosspiece region (8). The distance (A) between two cooling channels (4) adjacent to each other in transitions (6) is smaller than distance (B) in the remaining wall sections (9).

  • Patent number: 6918428
    Abstract: A chill tube made of copper for the continuous casting of metals has a multi-corner inner and outer cross section and a nominal wall thickness which amounts to 8% to 10% of the separation distance of the inner surfaces lying frontally opposite each other at the tube opening. The inner surfaces are placed indirectly under the heat-removing influence of a cooling medium suppliable from the outside to the tube wall. In the height range of the bath level of the liquid metal, the wall thickness is reduced over the entire circumference by 10% to 40% of the nominal wall thickness.

  • Patent number: 6874564
    Abstract: A liquid-cooled mold for a continuous casting of metals, including mold plates made of copper or a copper alloy, which are connected respectively to an adapter plate or a cooling-water tank by clamping bolts. The mold is characterized in that the clamping bolts are fastened to plateau pedestals which project in an island-like manner from the cooling arrangement side of the mold plate, which jut at least partially into a cooling arrangement gap formed between the mold plate and the adapter plate or the cooling-water tank, respectively, and have a streamlined shape adjusted to the flow direction of the cooling arrangement.

  • Patent number: 6827127
    Abstract: A method for blasting calibrating a chill mold (1) is provided. A calibrating mandrel is inserted into chill mold (1), thereafter an explosive material is placed on the outer surface (4) of chill mold (1) and is ignited. The inner side (3) of chill mold (1) is pressed against the calibrating mandrel by the explosive force, and brought to the setpoint measure. In the mold wall (2), chill mold (1) has bores (5) for cooling means and for measuring elements, which extend in the longitudinal direction (LR) of chill mold (1) and exit at the end faces (6, 7) of mold wall (2). Before the blasting calibration, the bores (5) are filled up with a free-flowing material and tightly closed. The free-flowing material is preferably an incompressible fluid and/or a bulk material.
