Graphite block is made of domestic petroleum coke, with carbon content above 99%. We have vibrated,molded and isotropic graphite block. They are widely used in such fields as mechanical , electronics, chemical industry and other new industries.
We can machine to specific shapes according to customers' requirements.
Graphite rotor is a component of aluminum alloy smelting supporting equipment. Hydrogen and oxidation waste slag will be produced in the process of aluminum alloy smelting, which should be purified and removed by refining degasser. Graphite rotor is one of the indispensable accessories of refining degasser. Graphite rotor is composed of rotor rod and nozzle.
Material: impregnated high-purity molded graphite and three special anti-oxidation treatments
Graphite rotor advantages: a. Chemical stability: graphite has good chemical stability at room temperature and can resist acid, alkali and organic solvent corrosion. b. Plasticity: graphite has good toughness and can be ground into very thin sheets. c. Thermal shock resistance: when graphite is used at room temperature, it can withstand the drastic change of temperature without damage. When the temperature changes suddenly, the volume of graphite changes little and there will be no cracks.
