Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a ceramic hybrid filter specifically designed for filtering molten metal. The filter is composed of at least two porous ceramic filters and an active filtration layer. The unique structure allows the filter to remove different types of inclusions (impurities) with varying chemical compositions that are present in the molten metal, thus improving the purity and quality of the final metal product.

Use CasesContent extracted from patent full text and abstract with AI.

  • Filtration of molten metal in metal foundries to improve metal quality
  • Production of high-purity aluminum, steel, or other metals
  • Removal of chemical impurities during metal casting processes
  • Use in manufacturing processes requiring extremely pure metal alloys
  • Integration into automated metal processing lines

BenefitsContent extracted from patent full text and abstract with AI.

  • Removes a wider range of impurities due to hybrid structure and active filtering layer
  • Improves the quality and purity of final metal products
  • Reduces defects caused by inclusions in cast metals
  • Increases efficiency of metal filtration processes
  • Adaptable for various types of metals and processing environments

Patent Abstract

Keramischer Metallschmelze-Hybrid-Filter zur Entfernung von Einschlüssen unterschiedlicher chemischer Zusammensetzung, aus wenigstens einem ersten porösen keramischen Filter, einem zweiten porösen keramischen Filter und einer aktiven Filtrationsschicht, die miteinander verbunden sind, wobei die porösen keramischen Filter eine Makroporosität von 8 bis 30 ppi und eine chaotische Porenstruktur aufweisen und die aktive Filtrationsschicht zwischen dem ersten porösen keramischen Filter und dem zweiten porösen keramischen Filter angeordnet und derart ausgebildet ist, dass diese endogene und exogene Einschlüsse mit einer anderen chemischen Zusammensetzung filtriert, als der erste und der zweite poröse keramische Filter.
