Product Description Description and Working Principle of Aluminum degassingAluminum degassing is a process used in the manufacturing of aluminum alloy castings. During the aluminum and aluminum alloy smelting process, hydrogen generated by chemical reaction with water vapor diffuses into the molten aluminum, causing internal structural defects in aluminum products. To avoid this defect, most aluminum plants use dissolved gas flotation to purify the molten aluminum by injecting inert gases such as nitrogen and argon into the molten aluminum. As inert gas diffuses and rises, hydrogen is brought to the surface of the molten aluminum. Description of Aluminum degassing graphite rotorAluminum degassing graphite rotor is a part of aluminum alloy smelting equipment, which can help remove hydrogen and oxidation residues. The aluminum degassing graphite rotor forms bubbles on the contact surface between the molten aluminum and inert gas, and increases the gas-liquid contact area, thereby accelerating the diffusion and removal of hydrogen. At the same time, the aluminum degassing graphite rotor can also adsorb and remove oxidization residues in the molten aluminum, and improve the quality and performance of the aluminum alloy. High-Performance Graphite Rotors & Impellers for Aluminum Melt ProcessingOur premium-grade graphite rotors and impellers are engineered for superior performance in aluminum melt degassing and purification systems. Designed to withstand extreme operational conditions, these components deliver unmatched durability and efficiency in molten aluminum treatment applications. Key FeaturesHigh mechanical strengthLow coefficient of thermal expansionGood thermal shock resistance.Good chemical stability, and excellent resistant to acids, bases and organic solvents.No wettability to molten aluminum, and do not chemically react with aluminum.Advanced Oxidation Protection: Special anti-oxidation treatment extends service life.Precision Engineering: CNC-machined to ±0.01mm tolerance for perfect balance and vibration-free operation Special TreatmentImpregnation anti-oxidation treatment: To extend the service life of the aluminum degassing graphite rotor shaft, we fill the pores of the graphite material with exclusive technology and nano-antioxidants, processed the graphite rotor shaft through vacuum impregnation, pressurization, and curing treatment to improve its anti-oxidation performance.Coating anti-oxidation treatment:Except for the threads, exclusive coating materials are applied to the impregnated anti-oxidation graphite rotor and shaft. The coating material does not penetrate into the aluminum, but adheres well to the graphite material. Due to its heat resistance, anti-oxidation, corrosion resistance, and abrasion resistance, the service life of the aluminum degassing graphite rotor and shaft is greatly extended after further coating treatment.Technical Data of Graphite Material: Isostatic GraphitePropertyKBD-5KBD-6KBD-7KBD-7BKBD-8UnitApparent Density 1.851.901.821.821.90g/cm3Max Grain Size13-158-108-1013-158-10μmAsh value ≤500≤500≤500≤500≤500ppmSpecific Electrical Resistivity8-108-911-1311-1311-13μΩmFlexural Strength 4655515960MpaCompressive Strength 8595115121135MpaShore Hardness4853657070HSDThermal Expansion (room temperature to 600oC)4.754.85.85.85.8510-6/oCMolded Graphite PropertyKBG-4KBG-5Unit Apparent Density ≥1.80≥1.85g/cm3Ash value ≤500≤500ppmShore Hardness≥40≥45HSDSpecific Electrical Resistivity ≤12≤12μΩmFlexural Strength 3841MpaCompressive Strength 8187MpaMax Grain Size 2525μmVibration GraphitePropertyTSKGSKUnitApparent Density≥1.70≥1.72g/cm3Max Grain Size ≤2≤0.8mmSpecific Electrical Resistivity8-10≤8.5μΩmFlexural Strength ≥12.5≥15MpaCompressive Strength ≥28≥35MpaPorosity≤24≤20%Ash value ≤0.3≤0.3% Strict Quality Control Ensures High Quality Products Safe Packing Question and Answer:Q:Are you a manufacturer or trading company?A:We are a manufacture for graphite material and graphite machined products.Q:How can you gurantee the quality?A:We have the most advanced equipments in our Lab and professional quality control team.We can gurantee each batch of the product with the stable quality.Q:Can you offer samples?A: Yes, we offer samples to testQ: Delivery time?A:Around 10 days.
