Ceramic Filters and Filter Systems for Continuous Metal Melt Filtration

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

This patent describes new types of ceramic filters and filter systems specifically designed for use in continuous metal melt filtration, such as in steel casting processes. The invention introduces replaceable and/or rotatable filter bodies that can be easily swapped out or rotated within a distributor channel to handle high volumes of metal and overcome the limitations of traditional filters. These filters can be installed for short intervals and are made in specific geometries like open-celled foam, honeycomb, or spaghetti shapes for improved filtration.

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

• Continuous casting of steel and other metals in industrial foundries.
• Filtration in metal processing plants to remove impurities during melting and casting.
• Integration in automated casting lines for improved metal quality control.
• Retrofit or upgrade of existing metal melt filtration systems for increased throughput and efficiency.

BenefitsContent extracted from patent full text and abstract with AI.

• Allows for higher throughput of metal melt without compromising filtration quality.
• Enables quick replacement or rotation of filters for uninterrupted operation and less downtime.
• Provides flexible filter geometries optimized for different filtration needs.
• Improves removal of impurities, resulting in higher quality cast metals.
• Reduces operational costs by extending filter life and minimizing system shutdowns.

Patent Abstract

With respect to ceramic filters and filter systems for continuous metal melt filtration, to be able to counter high throughputs of steel melt and also the limitations of filter capacities during continuous casting, an alternative technological approach involves the use of novel, replaceable, and/or rotatable filter bodies at positions in the distributor channel. In some cases, the replaceable and/or rotatable filter bodies may be inserted into the distributor channel for 10 seconds to 30 minutes before being replaced. The filter bodies may be configured as an open-celled foam ceramic or a honeycomb body or a spaghetti filter and serve as a filter geometry of the replaceable and/or rotatable filter bodies in the distributor channel.
