Basic Information

Manufacture crucibles from graphite of EG,PGM,chamotte-graphite on Your sketches or drawings d-from 10 to 500 mm. Graphite crucibles are used for melting ferrous, non-ferrous and precious metals in furnaces, direct heating and induction electric furnaces in a vacuum or protective atmosphere at temperatures up to 2500°C. Crucibles, graphite recommended for use with melts of copper, aluminum, zinc and other metals and their alloys. Crucibles of graphite have several advantages over cast iron, steel, and fireclay crucibles. First, the graphite crucibles have such a unique property as nesmeshivaemost crucible melts metals. Second, in addition to melting metal in a crucible of graphite is very important chemical reaction to remove oxygen in the pure form of the metal melt and the recovery of oxides of the metal to clean metal. That gives you the opportunity to obtain high-quality castings with low oxygen content and low the number of pores. Third, in the process of melting steel and cast iron in a crucible of graphite, the amount of carbon disappeared in the melting process from the molten state is recovered from the walls of the graphite crucible. Fourth, the destruction of the graphite crucible in the process of long-term operation is not instantaneous, as the fireclay of the crucible, and for some time, giving the opportunity to finish the melting without stopping the process. Despite the higher cost of graphite crucibles in comparison with the others, these properties put the graphite crucible out of the competition. The graphite crucibles are made of various heat-resistant grades of graphite, which ensures their reliability and durability. And the graphite crucible can be used repeatedly with the boring or grinding after each cycle. The nonferrous metallurgy enterprises use graphite crucibles of different capacities and designs, depending on the design of the furnace or induction unit. By construction, the inductive devices can be divided into installation with top casting and bottom casting. In particular, a graphite crucible with bottom pouring method require the use of additional shut-off rod tube. Some stocks are provided in the inner hole for thermocouple for temperature control of the discharge of the metal. If the graphite crucible has a hole in the wall, in this case, the locking rod is made solid. The graphite crucibles are made of any sizes (conical, cylindrical and special shapes) according to customer's drawings, based on the maximum dimensions of the workpiece. Conical graphite crucibles are mainly used for manual casting metal (capture with this casting rests on the conical portion of the crucible). Cylindrical graphite crucibles used in high frequency furnaces from which the casting metal is produced when tilting the furnace. The shaped graphite crucibles are used for melting ferrous, non-ferrous, solid state of metals and alloys. Thanks malosolenoj and good conductivity these crucibles can be used for contact of the electric smelting of precious metals. Special graphite crucibles can be used for melting non-ferrous and precious metals, smelting of metals, semiconductor with stirring of the charge, form molds for the casting of laboratory specimens and for the smelting of precious metals.
