As the core equipment for purifying molten metal in the casting industry, the foam ceramic filter, with its three-dimensional connected porous structure, can effectively intercept impurities such as oxide inclusions and refractory chips in the molten metal, improve the purity of molten metal, and is widely used in various casting processes such as aluminum melting casting and precision casting. However, in the actual production process, the foam ceramic filter is prone to cracking, blocking and other problems, which not only affects the filtering effect, leading to defects such as slag inclusion and porosity in the casting, but also may interrupt the production process, increasing the production cost and material consumption of the enterprise. With the transformation of casting industry to precision and green, clarifying the core causes of cracks and blockages of foam ceramic filters and formulating targeted solutions have become the key issues for enterprises to ensure stable production and improve product quality.

Foam ceramic filter is the core supporting equipment for liquid metal purification in the casting industry. Its filtering effect directly determines the purity of liquid metal, and then affects the quality of castings; The service life is closely related to the production cost and efficiency of the enterprise, and is an indispensable and important link in the full process control of casting production. In various casting processes such as aluminum melting casting and precision casting, the foam ceramic filter, with its three-dimensional connected porous structure, effectively intercepts impurities such as oxide inclusions and refractory chips in the molten metal, and provides guarantee for the production of high-quality castings. However, in practical applications, the filtering effect of the filter is easily attenuated and the service life varies greatly due to various factors. How to clarify these influencing factors and achieve scientific control has become a key issue for casting enterprises to improve quality and efficiency, and reduce losses.

As the core equipment for purifying molten metal in the casting industry, foam ceramic filter is widely used in various casting processes such as aluminum melting casting and precision casting. Its stable operation directly affects the purity of molten metal and the quality of castings. In actual production, many casting enterprises have the problem of neglecting the preheating process before using the filter, which leads to faults such as cracking and damage of the filter. This not only affects the filtering effect and shortens the service life, but also may interrupt the production process and increase production costs. With the transformation of casting industry to precision and high efficiency, it is necessary to clarify the preheating of foam ceramic filters before use and master scientific preheating points, which has become an important measure for enterprises to standardize production, improve quality and efficiency, and reduce loss.

As the core supporting equipment for liquid metal purification in the casting industry, the foam ceramic filter, with its three-dimensional connected porous structure, can effectively intercept impurities such as oxidation inclusions and refractory chips in the liquid metal, improve the purity of liquid metal, and directly affect the quality and production efficiency of castings. There are many kinds of casting processes, and there are significant differences in liquid metal temperature, impurity characteristics, and accuracy requirements between different processes. If the selection of foam ceramic filter does not match the process, it will not only fail to play a purification role, but also may lead to filter cracking, plugging and other failures, shorten service life, increase production costs, and even affect production smoothness. With the transformation of casting industry to precision and diversification, how to select appropriate foam ceramic filters according to casting technology has become a key issue for enterprises to standardize production, improve quality and efficiency, and reduce loss.

As the core carrier of liquid metal purification in the casting industry, foam ceramics, with its unique structural characteristics and stable working performance, are widely used in various processes such as aluminum melting casting, precision casting, ordinary sand casting, and become the key equipment to ensure the purity of liquid metal and improve the quality of castings. In actual production, the foam ceramic filter can efficiently intercept impurities such as oxidation inclusions, refractory chips, sand grains and so on in the molten metal, and reduce defects such as slag inclusion and porosity in castings. However, many enterprises do not understand its filtering working principle deeply, which leads to the inability to give full play to the equipment efficiency, or even affect the filtering effect due to improper operation. With the transformation of the casting industry to precision and green, in-depth analysis of the working principle of foam ceramics in liquid metal filtration and mastery of its core mechanism have become an important basis for enterprises to standardize filtration operations, optimize purification processes, and improve quality and efficiency.
