METALLIC BELT CONTINUOUS ANNEALING METHOD AND APPARATUS FOR PERFORMING THE SAME Russian patent published in 2008 - IPC C22F1/16 C21D1/26 G06K19/02 H01F1/153

Abstract RU 2316610 C2

FIELD: processes for treating metallic belts and producing magnetic-mechanical markers for electronic inspection of articles.

SUBSTANCE: method comprises steps of annealing thin belt of metallic ferromagnetic alloy at continuously transporting it through furnace for imparting to it predetermined magnetic characteristics and for eliminating lengthwise curvature of belt caused by manufacturing process. At process of heat treatment belt is guided along practically straight duct of clamping attachment of annealing furnace. Said duct is characterized by weakly bent portions along its length, namely in zone of belt introducing in annealing furnace. Slightly bent duct provides improved heat contact between belt and heat accumulator.

EFFECT: possibility for performing process with very high annealing rates without deterioration of belt characteristics.
