Abstract

A method of continuously processing metallic strip material comprises the successive steps of applying a coating of electrical insulating material to a strip material, heating the strip material to a first predetermined temperature to react the insulating material with a strip material to provide an adherent solid insulating filament on the surfaces of the strip material, further heating the strip material to a second predetermined temperature, applying a first predetermined longitudinal tension to the strip material as it is being heated to the second predetermined temperature, flattening the strip material where it is at said second predetermined temperature and first predetermined tension, further heating the strip material to a third predetermined temperature, applying a second predetermined longitudinal tension to the strip material while it is being heated to the third predetermined temperature to anneal the strip material, cooling said strip material at a predetermined weight for maintaining said second predetermined tension, grading the strip material to provide an indication of electrical quality of the strip material, applying a third predetermined tension to the strip material, and cooling the strip material when it is being subjected to the third predetermined tension. The magnetic strip material may be of silicon-iron which has been processed to provide the desired crystal structure and grain orientation. The insulating means may comprise aqueous phosphoric acid, mixed with magnesium oxide, magnesium hydroxide, or other suitable refractory material.ALSO:A method of continuously processing metallic strip material comprises the successive steps of applying a coating of electrical insulating material to a strip material, heating the strip material to a first predetermined temperature to react the insulating material with a strip material to provide an adherent solid insulating filament on the surfaces of the strip material, further heating the strip material to a second predetermined temperature, applying a first predetermined temperature, applying a first predetermined longitudinal tension to the strip material as it is being heated to the second predetermined temperature, flattening the strip material where it is at said second predetermined temperature and first predetermined tension, further heating the strip material to a third predetermined temperature, applying a second predetermined longitudinal tension to the strip material while it is being heated to the third predetermined temperature to anneal the strip material, cooling said strip material at a predetermined weight for maintaining said second predetermined tension, grading the strip material to provide an indication of electrical quality of the strip material, applying a third predetermined tension to the strip material, and cooling the strip material when it is being subjected to the third predetermined tension.
