An Amorphous Alloy Magnetic Yoke Applied to High Frequency Induction Heating Furnace

Abstract

The invention relates to a functional device of an induction heating furnace for plate blanks, in particular to an amorphous alloy magnet yoke applied to a high-frequency induction heating furnace. The amorphous alloy magnet yoke applied to the high-frequency induction heating furnace comprises an upper amorphous alloy magnet yoke, an injection coil and a lower amorphous alloy magnet yoke, whereinthe induction coil is an annular coil arranged transversely and vertically; the upper amorphous alloy magnet yoke and the lower amorphous alloy magnet yoke are arranged at the upper end and the lowerend of the induction coil respectively. The amorphous alloy magnet yoke has the advantages that the amorphous alloy magnet yoke is simple in structure and reasonable in design, excellent restrictionand shielding effects can be achieved for external radiation of the induction heating furnace, the coil is prevented from heating an external transmission component, and the heat efficiency generatedby an eddy current effect can be reduced, so that the temperature is reduced, and then the induction heating efficiency of the furnace can be improved.

Description

technical field [0001] The invention relates to a functional device of a slab induction heating furnace, in particular to an amorphous alloy magnetic yoke applied to a high-frequency induction heating furnace. Background technique [0002] The induction heating furnace is a new type of equipment in the industrial heating furnace. The traditional heating method of the intermediate billet is to use gas heating. Although it can meet the heating and uniform heating requirements, the efficiency is low. Especially in the endless rolling slab continuous casting and rolling production line, the steel strip needs to be heated quickly and soaked before entering the finishing mill. The induction heating furnace can meet this requirement very well, but the electromagnetic induction has an To prevent the magnetic field from leaking outward and heating other components, it is necessary to restrain and shield the magnetic field outside the coil.

Problems solved by technology

[0003] The iron loss of the currently used yoke material is not low enough. In the high-frequency heating environment, its own heat generation is relatively large, resulting in low coil heating efficiency and large heat loss, which cannot meet the needs of the high-frequency induction heating environment.
