Steel Melt Filter and Method for Its Manufacture

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

This patent describes a ceramic filter designed for molten metal filtration, featuring a support material with a special surface coating. The coating has the same chemical phase components as the undesirable non-metallic inclusions in the molten metal, making it particularly effective at trapping these impurities during the filtration process. The patent also covers a process for manufacturing such specialized ceramic filters.

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

• Filtration of molten steel and other metals in foundries and metal casting operations
• Improving the purity of metal products such as rods, sheets, or machine parts
• Use in steel manufacturing plants to reduce non-metallic inclusions and enhance product quality
• Application in the production of high-purity alloys for aerospace, automotive, and electronics industries

BenefitsContent extracted from patent full text and abstract with AI.

• More effective removal of non-metallic inclusions due to chemically matched surface coating
• Enhanced purity and quality of the final metal product
• Potential reduction of defects in metal castings, leading to stronger and more reliable components
• Can be produced using established ceramic filter geometries, making integration easier in existing processes

Patent Abstract

The ceramic filter for molten metal filtration on the basis of current molten metal filter geometries, is claimed, where the ceramic filter is provided as a support material with an active surface coating, which has same chemical phase components as inorganic non-metallic inclusions contained in the molten metal to be filtered. An independent claim is included for a process for manufacturing ceramic filters for molten metal filtration.
