Improvements to the continuous spray forming of metal strip

Continuous lengths of metallic strip are produced by a method in which a free falling stream of molten metallic material is atomised by a plurality of gaseous jets pre-heated to a temperature within the range 400 DEG C to 1200 DEG C to form a spray 6 of molten metal particles which collect on the su...

Zusammenfassung:Continuous lengths of metallic strip are produced by a method in which a free falling stream of molten metallic material is atomised by a plurality of gaseous jets pre-heated to a temperature within the range 400 DEG C to 1200 DEG C to form a spray 6 of molten metal particles which collect on the surface of an internally heated hollow receptor roll 10 and are peeled from the receptor roll in the form of a continuous strip. The receptor roll may be coated with a dried layer of colloidal silica after shot blasting.
