Working Principle of Graphite Rotor
The graphite rotor is composed of a rotor rod and nozzle. The transmission system drives the graphite rotor to rotate, and Ya gas or nitrogen is blown into the aluminum melt through the rotor rod and nozzle. The high-speed rotating graphite rotor disperses the Ya gas or nitrogen entering the aluminum melt to form many small bubbles, which are dispersed in the molten metal. At the same time, the rotating rotor also promotes the diffusion of hydrogen and inclusions in the aluminum melt. What is the purpose of the graphite degassing rod to make it contact with the bubbles? The bubbles absorb the hydrogen in the melt according to the principle of gas differential pressure and surface adsorption, The oxidized slag inclusion is absorbed and brought out of the melt surface with the rise of bubbles so that the melt can be purified.
Application of Graphite Rotor
Graphite rotor has excellent characteristics such as conductivity, thermal conductivity, lubricity, chemical stability, plasticity, and thermal shock resistance, so it is used in the following aspects:
as refractory
as conductive material
as lubricating material
making heat exchanger, reaction tank, condenser, combustion tower, absorption tower, cooler, heater, filter, and pump equipment
as casting, sand turning, die pressing, and high-temperature metallurgical materials
as deceleration material in atomic reactor
adding a certain amount of carbon graphite powder into the water to prevent boiler scaling
as pencil lead, pigment, and polishing agent
