Bauxite ceramic filter material is a high-quality ceramic filter element, which has the characteristics of high temperature resistance, corrosion resistance, high filtration accuracy, stable filtration effect and long service life. It is made of bauxite after high temperature firing, and the molten oxide formed on the surface has a good resistance to the molten metal and can play a role in protecting the molten steel.
The preparation of bauxite ceramic filter media requires steps such as raw material preparation, molding, drying, and sintering. Among them, the molding can be made into a green body by mud, grouting, pressing and extrusion; Drying can be done by natural drying, hot air drying, electric heating drying and microwave drying; The sintering temperature is usually above 1200 degrees. In the sintering process, it is necessary to pay attention to the control of the sintering atmosphere, because the sintering effect and product performance are different under different atmospheres.
In addition to the preparation of raw materials and the sintering process, the preparation of bauxite ceramic filter media also needs to pay attention to the uniformity of the filter pores and the stability of the filtration performance. Therefore, multiple test burns and performance tests are required during the preparation process, and the formula and process parameters are constantly adjusted to ensure the quality and performance of the final product.
In short, bauxite ceramic filter media is a high-quality ceramic filter element material, and its preparation process needs to pay attention to the steps of raw material preparation, molding, drying and sintering, and constantly adjust the formula and process parameters to ensure the quality and performance of the final product.
