Abstract

The invention relates to ceramic filters and filter systems for continuous metal melt filtration. The filters and the systems are configured by a manner that replaceable and / or rotatable filter bodies may be inserted into the distributor channel for 10 seconds to 30 minutes.

Description

technical field [0001] The present invention relates to a ceramic filter and filter system for continuous molten metal filtration. Background technique [0002] The question of the workability of metal parts is generally associated in the technical field with the concepts of strength of the material used and toughness of the material used. Both properties depend largely on the purity of the materials used. However, this concept is not a unit of measurement, but rather an overall statement about the probability, size distribution, morphology and chemical type of so-called non-metallic inclusions (NME). Safety components, thin-walled or thick-walled castings or forged parts with high demands on strength, toughness and fatigue resistance may not be used due to inadmissible NME components or lead to a drastic reduction of safety-related properties, such as notched impact toughness down to 40%. Non-metallic inclusions are referred to as solid form contaminants. It can be intr...
