Problems solved by technology

[0004] The disadvantage of the known method is mainly that, as a result of filling the casting container with a bucket before starting to transfer the molten metal from the casting container into the mold, eddy currents and mixing of the metal scale with the molten metal can already occur in the melt and thus may seriously damage the microstructure of the resulting casting

Embodiment Construction

[0034] As an introduction, it should first be explained that in the various embodiments described differently, the same components are provided with the same reference numerals or the same component names, and the disclosure content contained in the entire description can be transferred to the design according to the meaning. On the same part with the same reference number or the same component name. Furthermore, the orientation descriptions selected in the specification, such as up, down, sideways, etc., are relative to the direct description and the accompanying drawings, and these orientation descriptions can be transferred to the new direction according to the meaning when the orientation changes. orientation.

[0035] The exemplary embodiments show possible implementation variants of the solution according to the invention, and it should be pointed out here that the invention is not restricted to the specifically illustrated implementation variants of the invention, but r...

Abstract

The invention relates to a method for casting castings according to the tilt casting principle, in which molten metal (1) is transferred from at least one tiltable casting container (2) into a casting mold (3) with a molding The mold gap (4) of the casting, in which the molten metal (1) is taken directly from the stationary crucible furnace (5) by means of a pouring container (2), in which the molten metal (1) is Metal oxide scale (6) is produced on the metal oxide scale (6), and the pouring container (2) containing the molten metal (1) and the metal oxide scale (6) floating thereon is moved closer to the casting mold (3), and the pouring container (2) is The molten metal (1) is transferred from the pouring container (2) into the casting mold (3) by co-rotating the casting mold (3) about the rotation axis (a) from the starting position to the end position, and the metal oxide scale (6) Floats on the molten metal (1) during transfer and mostly floats on the molten metal (1) and essentially remains on the surface of the molten metal (1).

Description

technical field [0001] The invention relates to a method for casting castings according to the tilting casting principle, wherein molten metal is transferred from at least one tiltable pouring container into a mold having a mold cavity for shaping the casting, wherein the pouring Vessels take molten metal directly from a stationary crucible furnace. Background technique [0002] A method of the type mentioned at the outset is known from DE 10 2009 023 881 A1. [0003] A method for tilt casting is known from WO 2010 / 058003 A1. In this known method, the pouring process is performed by inclining the pouring container. In this case, the casting container or the melt level in the casting container is higher than the casting mold, so that the melt flows into the casting container with a relatively high kinetic energy. In known solutions, as is common in such methods, the melt is taken out of the stationary crucible furnace with a bucket and then transferred from the bucket into...
