Graphite crucible in the inspection work before the application of graphite crucible has excellent thermal conductivity and heat resistance, in the whole process of high temperature application, linear expansion coefficient is small, has a certain resistance to sudden heat, cold. Strong corrosion resistance to acid and alkaline solutions, with high quality organic chemical reliability. In the metallurgical industry, forging, mechanical equipment, chemical plants and other industries are widely used for alloy tool steel smelter and rare metals and aluminum alloy smelting, and has a good safety engineering practical effect.

The graphite rotor works by breaking nitrogen (or argon) blown into the aluminum melt into a large number of dispersing bubbles, which are dispersed in the liquid metal.

he graphite rotor works by breaking nitrogen (or argon) blown into the aluminum melt into a large number of dispersing bubbles, which are dispersed in the liquid metal. Bubbles in the melt by the gas differential pressure and surface adsorption principle, absorb the hydrogen in the melt, adsorption oxidation slag, and with the bubble rise and be taken out of the melt surface, so that the melt can be purified. Due to the small dispersion of bubbles, they are evenly mixed with the rotating melt, and then rotate to form a spiral shape and slowly float up. The contact time with the melt is long, and no continuous straight rising air flow will be formed, thus removing harmful hydrogen in the aluminum melt and significantly improving the purification effect. High strength graphite rotors can be used in the following industries:

Graphite crucible, as an indispensable machine and equipment for copper smelter and alloy copper, has excellent characteristics and is widely used in casting industry. To adhere to the excellent effect of graphite crucible, make full use of the advantages of graphite crucible, should pay attention to the operation method of high purity graphite crucible:
