GMG Degassing Tube
GMG degassing Tube is a specially made for online refining of molten aluminum and purification of the molten pool. By relying on its own porous and breathable graphite structure, it introduces refining nitrogen and argon gases to disperse tiny bubbles, effectively removing hydrogen from the molten aluminum and improving the casting quality.
DetailKey Benefits
✔Wide high-temperature tolerance: stable from 1000℃~1700℃, no deformation or fracture under typical aluminum, copper, zinc smelting temperatures
✔Superior chemical stability: inert against molten non-ferrous metals to avoid melt contamination
✔Uniform gas permeability & high degassing efficiency: fine dispersed gas enlarges liquid-gas contact area to eliminate hydrogen and suspended impurities, minimizing casting pinhole defects
✔Long service life & low maintenance cost: thermal shock and molten aluminum erosion resistant, outperforming regular ceramic alternatives to reduce spare part expenses and production downtime
