Bubble bed green melting equipment
Bubble bed green melting equipment
The melting furnace bubble bed without flux developed by Fujian Metal-new adopts pure physical metallurgical method instead of chemical metallurgical method of flux refining, that is, without refining agent, the content of inclusions and gases in aluminum melt can be reduced to the current purification level of flux spray refining; The chemical composition uniformity of the melt in the furnace can be achieved by using gas wave stirring, which can ensure the quality of alloying and the purification effect of good purity. Certified by the National Non-ferrous Metal Industry Association, it has reached the international leading level. Has won the national non-ferrous metal science and technology progress award, has applied for invention patents.

2. Owned patents and certificates
3. The product has the following advantages:
- Hydrogen content [H] =0.18~0.25ml/100gAl (degassing rate reaches the level of refining agent) off-line slag testing ≤0.08mm2/kgAl, oxide film ≤8 points, and all are thin and small size;
- No chlorine, fluorine pollution gas emissions, no fluorine containing solid waste emissions of major hidden dangers;
- The total amount of aluminum slag is reduced by half, only 50% of the flux purification process;
- The service life of the furnace is extended, there is no slag formation, the melting pool is clean, and the volume is unchanged.
- Reduce the opening times and opening time of the furnace door, and save energy > 5-10 cubic meters /t Al;
- The process is produced under the dynamic equilibrium state of pure inert gas purification and protection of argon, which reduces the metal oxidation and burning loss, overcomes the gravitational field effect and temperature field effect, reduces the microsegregation and genetic influence of alloying elements, and has a good technological advantage for the production of high-quality aluminum alloys.
