Description

Technical Field

[0001] The utility model relates to the technical field of ceramic filter sheets, in particular to an extrusion device for preparing ceramic filter sheets. Background Art

[0002] Honeycomb ceramic filters are widely used in filtration of molten metals in metallurgy and foundry industries. They are made of mullite (cordierite) ceramic material and high-quality, high-density straight-hole mesh, which makes the product highly resistant to thermal shock and high casting temperatures. The straight-hole design ensures a balance between flow and strength, effectively removes impurities and slag particles, and greatly improves the mechanical properties, surface quality and product qualification rate of castings.

[0003] At present, in order to avoid deformation of the filter plates caused by drilling, some devices for preparing ceramic filter plates perform drilling and extrusion together. However, after the raw material is pressed and punched, directly ejecting the raw material will cause friction deformation between the raw material and the inner wall of the mold, thereby reducing the final demolding effect. For this reason, we propose an extrusion device for preparing ceramic filter plates to solve the above-mentioned problems. Utility Model Content
