Vacuum Ceramic Filter Plate

The selection of ceramic filter plates depends on the impurity content in the aluminum melt, the flow rate of the melt injection, and the quality requirements of the final cast product.

Due to the high content of impurities and average quality of cast products, ceramic filter plates with larger mesh sizes can be selected, and a coarse glass fiber cloth filter can be added in front of the filter plate. At this point, it is important to use glass fiber cloth for coarse filtration in semi continuous casting. It can intercept the flow of slag when opening the eyes and the slag washed down by the flow channel to prevent clogging of the filter plate.

Casting products have high quality requirements. New foam ceramic filters with small mesh holes, i.e. large mesh size, are used for filtering. For example, Fujian Ruimin Aluminum Industry and Nanfang Aluminum Industry produce aluminum foil blanks, Henan Mingtai Aluminum Industry produces high-quality hot rolled slabs, Northeast Light Alloy Processing Factory produces high-quality military aluminum, and Guangdong Zhongshan Hesheng Aluminum Industry produces high-quality industrial profiles with the second generation of foam ceramic filter plates produced by Fuzhou Maite New High Temperature Materials Co., Ltd. * To highlight the selection of 30ppi and 60ppi/double filters with specifications of 305 × 305 × 50, 381 × 381 × 50, 432 × 432 × 50, and 508 × 508 × 50 Grade filtration technology, achieving ideal cleanliness and obtaining good results. The selection of filter plate specifications is based on the flow rate and total throughput of the melt. If the flow rate is high, the total throughput is large, and the filter plate holes are small, then larger specifications should be selected.
