Responsive To Thermal Condition Patents (Class 164/154.6)
  • Patent number: 11794255
    Abstract: A three-dimensional (3D) metal object manufacturing apparatus is operated to form sloping surfaces having a slope angle of more than 45° from a line that is perpendicular to the structure on which the layer forming the slope surface is formed. The angle corresponds to a step-out distance from the perpendicular line and a maximum individual step-out distance determined from empirically derived data. Multiple passes of an ejection head of the apparatus can be performed within a layer to form a sloped edge and the mass of the sloped structure is distributed within the sloped edge so the edge is formed without defects.

  • Patent number: 11684972
    Abstract: A three-dimensional (3D) metal object manufacturing apparatus has a thermally insulative layer between a platform on which an ejection head ejects drops of melted metal and a X-Y translation mechanism on which the platform is moved within an X-Y plane opposite the ejection head. The apparatus also includes a housing having an internal volume in which the platform and X-Y translation mechanism are located. In one embodiment, the thermally insulative layer is a plurality of spheres made of a thermally insulative material such as a ceramic made of zirconium dioxide or zirconium oxide. The thermally insulative layer protects the X-Y mechanism while the housing helps keep the surface temperature of the object being formed on the platform in an optimal range for bonding of the ejected melted metal drops to the object's surface.

  • Patent number: 8788084
    Abstract: The inflow of liquid metal into a continuous casting mold is set by a closure device. A measured actual meniscus value is fed to a controller determining a closure device target position on the basis of the actual and a corresponding target value. The measured actual value is fed to a disturbance variable compensator. The target position/corrected target position or a corresponding actual value are further fed to the disturbance variable compensator which determines the disturbance variable compensation value. The disturbance variable compensator has a model of the continuous casting mold for determining an expected value. A number of oscillating compensators determine a frequency disturbance proportion. The sum of the frequency disturbance proportions corresponds to the disturbance variable compensation value. The disturbance variable compensator has a jump determiner, by which it determines the jump compensation value by integrating the difference.

    Abstract: The invention concerns a method and a control device for automatically controlling the heat dissipation {dot over (q)} in a mold 200 for casting metal. The heat dissipation of the side plate of a mold is automatically adjusted to a preset set point {dot over (q)}set by suitable variation of the volume flow rate {dot over (V)} of a coolant 300 through the side plate. In accordance with the invention, to avoid the necessity, when different molds are used, of adapting the control of the heat dissipation each time to different thicknesses or coatings of the side plates or to different settings of the side plates during the casting operation or during the casting of different grades of steel, the actual value for the heat dissipation {dot over (q)} during a steady-state casting operation is suitably computed on a current basis from, among other things, the difference in the temperature of the coolant 300 at the coolant outlet and the coolant inlet of the side plate 200 and material constants for the coolant.
