Therefore, people have studied many purification methods. According to their different mechanisms and forms, they can be divided into adsorption purification, physical purification and filtration purification [1. Filtration purification is to make the molten metal flow through a certain medium, this medium captures the inclusions according to a certain mechanism, thereby purifying the metal. In 1978, the United States developed a new type of filter-ceramic foam filter, which provides a high-efficiency filter for the production of cast aluminum parts.<\/p>\n<p>The smelting of aluminum alloy is an important part of the aluminum alloy processing process, which is reflected in the alloying, purification and refinement processing technology of the smelting process. The removal of non-metallic inclusions in the aluminum alloy melt by the treatment of the flux in the furnace and the filtration of the ceramic foam outside the furnace has long become an important method for the purification of molten aluminum.<\/p>","protected":false},"excerpt":{"rendered":"<p>Ceramic Filters Foundry in China&#8217;s aluminum processing industry has been popularized, and there
