graphite melting crucible

  How to increase the service life of graphite crucibles in the smelting process. The main components of graphite crucibles are natural flake graphite and binders. Therefore, they have the advantages of fast heat conduction, high-temperature resistance, good thermal stability, and no reaction with molten materials. They are widely used in the smelting of non-ferrous metals. How to increase the service life of graphite crucibles in the smelting process. Crucibles are often used in metal recycling and processing equipment. In the recycling of aluminum dross, graphite crucible furnaces are generally adopted for smelting to separate aluminum dross from aluminum slag. However, graphite crucibles are prone to oxidation when used in a high-temperature and strongly oxidizing atmosphere, which significantly reduces their service life. With the development of non-ferrous metal smelting technology, its usage conditions have become increasingly harsh. According to investigations, the average life…
