Abstract

The invention discloses an amorphous alloy three-dimensional roll-core annealing furnace which comprises a cooling shell, a circulating fan, a heater, a heating chamber fixed in the cooling shell, a horizontal roller group, a tray arranged on the horizontal roller group, and a three-dimensional roll-core bracket arranged on the top surface of the tray, wherein an electrode facing the heating station of the tray is arranged on the side wall of the cooling shell; a heating chamber inlet is formed in the front side wall of the heating chamber; a heating chamber inlet baffle is arranged at the heating chamber inlet; a furnace opening which corresponds to the heating chamber inlet is formed in the side wall of the cooling shell; a furnace door is arranged on the furnace opening; multiple ventilating windows which can be independently opened and closed are formed in four side walls of the heating chamber; and multiple air holes are uniformly formed in the bottom plate of the heating chamber. According to the annealing furnace disclosed by the invention, the annealing process requirements of the amorphous alloy three-dimensional roll-core can be well met.

Description

technical field [0001] The invention relates to the technical field of transformer iron core processing, in particular to an annealing furnace and an annealing method for an amorphous alloy three-dimensional wound iron core. technical background [0002] Amorphous alloy three-dimensional wound core transformer is a new type of energy-saving and environment-friendly transformer. Since the transformer core is made of new amorphous alloy material and adopts a more reasonable three-dimensional structure, it can greatly reduce the no-load of the transformer itself. loss. However, like the silicon steel sheet three-dimensional coil core, when the amorphous alloy three-dimensional coil core strip is cut and wound, its own magnetic permeability is extremely reduced. Therefore, in order to obtain a qualified amorphous alloy three-dimensional wound core transformer, annealing must be performed after the iron core is wound. [0003] Different from the three-dimensional wound iron cor...
