1Smelting Metal: Ingot Mold is thermally stable, so it can be heated and cooled quickly, and it is resistant to alkali corrosion, and is used for smelting metals such as gold and silver. 2Thermal Shock Resistance: Graphite ingot mold has thermal shock resistance, electrical conductivity and thermal conductivity, which is more conducive to metal smelting and pouring. 3Strain Resistance: Graphite crucible has high temperature resistance. In the process, the thermal expansion coefficient is small, and it has certain strain resistance. 4Long Service Life: Melting ingot refines metals such as gold, silver, platinum and other alloys, which are durable and have a long service life, so it can be used for a long time. 5Usage: Melting ingot is widely used in experiments and industrial sectors, and is widely used in the smelting of alloy tool steel and the smelting of non ferrous metals and their alloys.
