The invention relates to a metal part that has a surface which is thermally or mechanically loaded to a greater degree than its surroundings when the metal part is being used and which is at least partly covered with a glaze or enamel layer. The invention also relates to a method for producing same. The metal part according to the invention allows the heat treatment to be carried out without any particular restrictions while still ensuring an optimal protection of the respective surfaces which are subjected to high loads when the metal part is used. This is achieved in that the glaze or enamel layer contains 2 - 35 wt.% of an addition of particles with respect to the enamel frits used to form the enamel layer, and the addition of particles is made of at least one material of the group consisting of glass, organic plastics, synthetic oxide mixtures, or melts, in each case having a thermal expansion coefficient of maximally 50 x 10-7 K-1 and a melting temperature of at least 500 °C.
A method for casting a cast part according to the tilt pouring principle includes pouring a molten metal from at least one tiltable casting vessel into a casting mold including a mold cavity which forms the cast part. The molten metal is ladled directly out of a bale-out furnace using the casting vessel, and a metal oxide skin forms in the casting vessel on the surface of the molten metal. The casting vessel containing the molten metal and the metal oxide skin floating thereon is brought to the casting mold. The molten metal is poured from the casting vessel into the casting mold by a common rotation of the casting vessel and casting mold about an axis of rotation. The metal oxide skin rises to the top of the molten metal during the pouring process, floating predominantly on top and on the surface of the molten metal.

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.
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.

METHOD AND DEVICE FOR CASTING A CAST PART FROM A METAL MELT
The invention relates to a method and a device for casting a cast part from a metal melt. During the method according to the invention, a casting mould, mounted in a pivoted mounting, comprising a mould cavity for shaping the cast part, a feed system and a pour channel, is rotated into a fill position and filled with metal melt. As a consequence of 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. The filling is continued until the casting mould, including the pour channel, is completely filled with metal melt. Then, the casting mould is sealed with a stopper placed in the filling opening of the pour channel, and is rotated into a solidification position, in which the melt present in the feed system is pushed against the melt present in the mould cavity. The casting mould is held in the solidification position until the metal melt present in the casting mould has reached a solidification state in which the cast part can be de-moulded.
The invention relates to a method and a device for casting a cast part G from a metal melt M. During the method according to the invention, a casting mold F comprising a mold cavity H that shapes the cast part G, a feed system 10 and a pouring channel 13, said casting mold being mounted in a bogie, is rotated to a fill position and filled with a metal melt. As a consequence of the effect of gravity, the melt flows through the pouring channel, wherein the main flow direction of the melt makes an angle relative to the acting direction of the force of gravity. The filling is continued until the casting mold F and the pouring channel 13 are completely filled with metal melt M. Then, the casting mold F is sealed by a stopper 18 placed in the fill opening 14 of the pour channel 13, and is rotated to a solidification position in which the melt M present in the feed system 10 is pushed against the melt M present in the mold cavity H. The casting mold G is held in the solidification position until the metal melt M present in the casting mold F has reached a state of solidification in which the cast part G can be de-molded.
The present invention relates to a casting mould for casting a cast part, in particular an engine block for an internal combustion engine, and the use of such a casting mould which is made up of mould parts 1, 2, 3, produced from moulding sand, and casting cores 4, 5, 6, 7, and has at least one casting core 4, 5, 6, 7 for forming a space in the cast part. The casting mould according to the invention makes it possible in a simple way to produce cast parts in which at least one locally confined portion is formed with a different microstructure than the rest of the cast part. This is achieved by a portion of the casting core 4, 5, 6, 7 being formed by a chill 9, which is made from a material of a thermal conductivity that is many times greater than the thermal conductivity of the remaining portion 8 of the casting core 4, 5, 6, 7, consisting of moulding sand.
