Macrospray Parting Layer Spray

Macrospray is used as a thin refractory parting layer for the removal of slag, steel and non-ferrous metals.

Macrospray products are alumina or alumina-silica particles in suspension.  When sprayed onto steel, cast iron or refractory linings, they will allow the easy dumping of skulls, removal of unwanted build-up or removal of solidified metal. The products are formulated to require infrequent or continuous mixing, depending on the customer’s request.
Macrosprays may be pumped with a variety of systems and sprayed with a simple orifice nozzle. Imacro can supply an air-operated diaphragm pump with suitable pipe and nozzle for spraying. We can also supply the schematic and bill of material for this system, if the customer prefers to purchase it locally.
