Definitions
- the present application relates to a method for producing a material cartridge for preserving a material mixture which is susceptible to corrosion from air, in particular a molten metal or one or more metal solids.
- the present application also relates to a container for use in such a method for producing a material cartridge and the produced material cartridge, comprising the container.
- the application also relates to a method for producing a
- Cast product using the material cartridge and a corresponding cast product Cast product using the material cartridge and a corresponding cast product.
- Mixtures of materials that react with air are used in a wide variety of fields of application, particularly in foundries.
- defined material mixtures, such as alloys, are essential, especially when there are high demands on material properties. Reactions of the defined material mixtures with constituents of the air lead to changes in the composition of the material mixtures, which results in a loss of quality.
- the processes here are typically designed for precisely defined alloys with predetermined material proportions.
- This defined alloy is then produced in several process steps that are connected with transport steps.
- the solid alloy components are preheated, the main alloy component is melted in a melting furnace and the alloy is precisely adjusted in a liquid state by adding the individual alloy components, for example by diffusion or active mixing.
- the liquid alloy is then transferred to transport containers and taken to a pouring device. There is typically a further transfer to a holding furnace, which keeps the alloy melt at a ge desired casting temperature.
- the alloy melt is now removed in batches from the holding furnace, for example by means of a pouring spoon, transported to a casting mold, for example with a robot arm, and there it is poured into the provided casting mold, for example a metallic permanent mold with inserted sand cores.
- Adjusting the alloy composition therefore requires a large number of measuring and testing equipment and foundries have to accept cost-intensive purchases of plant technology in the form of furnaces, transport containers, casting systems and logistics areas.

- Material mixtures based on aluminum have, in addition to the main component aluminum, typically at least silicon as a non-metallic component. These mixtures of materials are typically susceptible to nitrogen or oxide contamination.
- material mixtures based on iron typically have at least carbon as a non-metallic component. These material mixtures are typically susceptible to contamination by oxides and / or nitrates and / or nitrites. Mixtures of materials comprising sand / binder mixtures typically have quartz sand and / or organic binder constituents, for example hydrocarbon-based resins.
