Foundry Flux

Slag perlite as slag remover known as perlite ore-foundry flux. In application where slag perlite is introduced to the ladle during fill and after a heel of metal has been poured, it produces a gentle rolling action which cleans the metal by coagulating, impurities and floating them up to the slag layer. Repeated use increase ladle lining life by cleaning the walls and leaving a vitreous residual coating on the refractory. There are claims that slag perlite will also reduce the sulphur content of ferrous metal when added to the ladle during fill. It is probable that this is the result of the slag perlite collecting the products of desulfurization, raising them to the surface and holding them in the slag in such away that sulphur cannot readily re-enter the bath.

Slag perlite performs these functions without producing objectionable smoke or noxious fumes a significant benefit to the foundry man faced with ever tightening air pollution restrictions. Slag perlite could conveniently find use in continuous casting operations as an insulating covering on tundish and casting moulds. Other potential steel mill uses would be in molten iron transfer cars as an insulating barrier or in molten iron desulphurization practices where the slag must be skimmed off following treatment.

Packing: slag perlite is available in 50 kg. Bags.
