Aluminum ranks third among the elements in the earth's crust, second only to oxygen and silicon, and is the most abundant metal element in the earth's crust. Among the kinds of metals, it is the second largest type of metal after steel. With the development of non-ferrous metal technology, aluminum and aluminum alloys will be widely used in industry, agriculture, national defense and other industries with their unique advantages, especially the rapid development of automobile industry in recent years, which makes the application scope of aluminum alloy castings constantly expand and the quality requirements are getting higher and higher, so the technical level requirements for aluminum melting and heat preservation equipment are getting higher and higher.

Aluminum holding furnace is named after melting aluminum alloy and aluminum liquid and then standing and heating. The author has designed an aluminum holding furnace, which is equipped with a heating chamber, two aluminum inlets and outlets, namely an aluminum holding station and an aluminum casting water outlet. The internal insulation of molten aluminum is placed in static liquid, which can continuously provide necessary stability and ensure the temperature of molten aluminum. The furnace has the characteristics of high thermal efficiency, low metal combustion, high quality of liquid metal and accurate temperature control, and can continuously provide liquid aluminum.
