One of the main production methods of aluminum foam is the melt foaming method, which is to place the molten aluminum liquid mixed with a tackifier and a foaming agent in a foaming tank car for foaming. After the foaming is completed, the tank car is pulled out of the furnace cavity and cooled to obtain a large block.
