Coverflux 7R
Coverflux 7R is a flux cover specially prepared for use in reverberate melting of aluminum. It is
designed to prevent the removal of an excessive amount of metal in the slag or dross, and to protect
the surface of the molten metal from the furnace atmosphere so avoiding gas absorption and
metal losses.
Coverflux 7R is applied at an additional level of approx. 1.25 – 2.5kg per sq. meter of surface area.
Coverflux 7R should be lightly rabbled into the dross then allowed to react for approximately 10
minutes before removing, this is to allow time for the flux to activate the dross and insure that
entrapped metal can flow back into the bath.
