  • Patent number: 8901930
    Abstract: A method for detecting metal in an inner region of a caster mold during a casting process using a plurality of eddy current probe assemblies, wherein each of the plurality of eddy current probe assemblies is configured to generate a primary magnetic field passing through nonconductive mold material of the casting mold to the inner region of the casting mold and to provide a signal indicative of a detected secondary magnetic field caused by eddy currents induced in the metal.

  • Patent number: 8302659
    Abstract: A method and a device for casting a cast part from a metal melt. A casting mould in a pivoted mounting comprising a mould cavity shaping the cast part, a feed system and a pour channel, is rotated into a fill position and filled with metal melt. Due to the effect of gravity, the melt flows through the pour channel, wherein the main flow direction of the melt makes an angle relative to the acting direction of gravity. Filling is continued until the casting mould, including the pour channel, is completely filled. Then, the casting mould is sealed with a stopper and rotated into a solidification position, in which the melt in the feed system is pushed against the melt in the mould cavity. The casting mould is held in the solidification position until the metal melt has reached a solidification state in which the cast part can be de-moulded.

  • Publication number: 20100139884
    Abstract: The present invention relates to a casting mould for casting a casting, in particular an engine block for a combustion engine, as well as to the use of such a casting mould, comprising mould parts 1, 2, 3 and casting cores 4, 5, 6, 7 produced from moulding sand, and at least one casting core 4, 5, 6, 7 for the formation of a space in the casting. The casting mould according to the invention makes it possible, in a simple manner, for castings to be produced in which at least one locally closely confined section is formed with a microstructure which differs from the remainder of the casting. This is achieved in that a section of the casting core 4, 5, 6, 7 is formed by a chill 9 which is manufactured from a material of which the thermal conductivity is many times higher than the thermal conductivity of the other section 8 of the casting core 4, 5, 6, 7, consisting of moulding sand.
