Product details

Alumina ceramic filter & Tansparent Alumina Plate is a porous filtering element made of special ceramic materials, which is widely used in various industrial and daily life fields. Its core function is to remove impurities from fluids (liquids or gases) through mechanisms such as physical interception and chemical adsorption. It also has advantages such as high temperature resistance, resistance to acids and alkalis, corrosion resistance, and ease of cleaning and regeneration.

According to publicly available information, the main functions of ceramic filters can be summarized as follows:

1. Metal melt filtration (metallurgy and casting field)

‌Remove inclusions: Effectively filter out oxides, slag, non-metallic inclusions, etc. from molten metals such as aluminum liquid and steel liquid. 3

Rectified metal liquid flow: Reduces turbulence and bubble entrainment, prevents oxidation splashing, and improves the surface quality and internal density of the castings. 3

Improving casting performance: The experiment shows that it can reduce the scrap rate of aluminum alloys by 60-80% and increase the strength of the castings by 10-20% 3.

Adapted for automated production: Stable structure, simplifies the design of the pouring system, suitable for continuous and automated casting lines
