Aluminium Industry-Porous Plugs
Porous plugs for the aluminium industry allow gas to pass through but prevent aluminium from penetrating the pores. A very important step in the refining of aluminum is the introduction of inert gases (nitrogen or argon) through purging plugs.
Benefits of Purging:
- Significant improvement in melt rate
- Reductions in H2 content and Na concentration
- Thermal and chemical homogenization of the molten metal
- Reduced energy/Fuel consumption
- Reduced dross formation and metal loss
- Significantly less salt and chlorine are needed
RCGP-AL Porous Plug is a high strength and permeable refractory product, whose physical and chemical properties have been modified and permeability been precisely controlled to resist penetration by aluminium yet permit sufficient gas flow for effective treatment of the melt.
RCGP-AL Porous Plugs are applicable in all stages of aluminium melting, holding and transport; in stationary and tilting furnaces as well as in troughs and inline boxes.
