product description:
(Aluminum alloy) During the casting process, hydrogen generated by chemical reaction with water vapor is dispersed in the aluminum melt, resulting in internal structural defects of the final aluminum (aluminum alloy) material. In order to eliminate such structural defects, most factories adopt the "air floatation" degassing purification process, that is, injecting an inert gas such as nitrogen gas or argon into the aluminum melt, and using the dispersion and rise of the inert gas to bring the hydrogen out of the aluminum melt. Body fluid level.
According to the different aluminum (aluminum alloy) casting process, degassing purification is also divided into two types: intermittent degassing and continuous on-line degassing. However, in either case, degassing is used to open the gas and rotate the agitating action. The rotor is an essential part of the equipment. Graphite materials have become the material of choice for making degassing rotors due to their high temperature resistance, oxidation resistance, high strength and non-wetting properties with aluminum melt.
The degassing rotor made of graphite material is a graphite rotor, which is also called a graphite shaft and a graphite impeller.
Product advantages:
Raw material selection: special graphite developed by Carbon as raw material, high strength, high hardness, oxidation resistance, low porosity, abrasion resistance and erosion resistance;
Product processing: It is processed strictly according to customer's drawings. After installation, the components are closely matched and the concentricity is high, which effectively avoids mechanical stress damage;
Special treatment:
Impregnation and anti-oxidation: The anti-oxidation treatment of the final product is carried out by using Yinxuan carbon proprietary technology and nano-antioxidant, so that the micropores inside the graphite material are filled with anti-oxidant and the surface is covered with antioxidant, which effectively improves the high temperature resistance of the graphite rotor. Anti-oxidation and anti-scour performance, greatly extending its service life;
Coating resistance: The surface of the graphite rotor (except the threaded part) after impregnation and oxidation treatment is coated with Yinxuan carbon proprietary coating material. The coating material is not wetted with the aluminum melt, but It can be firmly combined with graphite materials, and is more resistant to high temperature, oxidation, abrasion and erosion than graphite materials. The service life of graphite rotors after coating treatment is further extended;
Local enhancement: According to the characteristics of the end user, the most easily consumed part of the graphite rotor is locally enhanced to achieve the longest service life at the lowest co

2. we have High quality Graphite Rotor for Aluminum industrial purification .graphite Blender/Degassing Rod (The shape of the impeller is streamlined, which can reduce the resistance during rotation, and the friction and scouring force between the impeller and aluminum alloy liquid is relatively small.Thus, the degassing rate is above 50%, the smelting time is shortened and the production cost is reduced.Widely used in aluminum alloy foundries and aluminum products factories.)
Regular sizes are generally:
1---rotor rod: diameter 50~120mm, length 600~1200mm;
Rotor head: diameter 120~350mm, thickness 40~90mm. We can process according to the drawings provided by your company, or take measurements in the field, and process them for your drawings.
2---Special unconventional sizes can be customized. As long as the drawings are provided, we can process them strictly according to the drawings.
Material index:
1----bulk density"1.72g/cm3 flexural strength"13Mpa compressive strength"26Mpa ash "0.3%
2----bulk density" 1.80g/cm3 flexural strength" 30Mpa compressive strength" 60Mpa ash "0.1%
Packaging and delivery time:
1--10--15 days after the contract is confirmed, it can be shipped, depending on the order quantity and the busyness of the shop.
2--Generally packed in plywood and packed with enough filler to protect the product from damage, such as: pearl cotton, bubble strip, styrofoam foam board, etc.
3. In the aluminum and zinc casting industries, nitrogen, argon or carbon tetrachloride are injected and sprayed into molten metal through graphite rotors for dehydrogenation. It can eliminate the bubbles inside the castings and improve their inner quality. Injects inert gases into the Metallic solution .
