Abstract

The invention provides a copper mould suction casting preparation device of an iron-based bulk amorphous alloy toroidal magnetic core and a method therefore. The preparation device of the invention comprises an electrode, a furnace chamber, copper crucibles, a copper mould, a mould core, a mould cavity, a suction casting pipe and a water cooling device. A plurality of copper crucibles are arranged in the furnace cavity, wherein, at least one copper crucible is used for suction casting, and the residues are used for melting. The electrode penetrates the furnace chamber and extends into the copper crucibles used for melting in the furnace cavity. Iron-based bulk amorphous alloy raw materials which are prepared according to the content requirement and are provided with soft magnet are put in the copper crucibles used for melting. The copper crucibles used for suction casting are provided with the water cooling device at the lower parts. The copper mould is arranged in the water cooling device. The mould cavity is internally provided with the mould cavity which is communicated with the copper crucible used for suction casting. The mould core is arranged in the mould cavity. The suction casting pipe which can suck alloy liquid in the copper crucible used for suction casting into the mould cavity with the mould core is arranged outside the mould cavity. The preparation device has the advantages of simple structure and convenient operation. The preparation method of the invention has the advantages of high preparation efficiency and simple processing conditions and can be carried out easily under the industrial production condition.

Description

technical field [0001] The invention is a copper mold suction casting preparation device and method for an iron-based bulk amorphous alloy ring magnetic core, and belongs to the transformation technology of the copper mold suction casting preparation device and method for an iron-based bulk amorphous alloy ring magnetic core . Background technique [0002] Due to its disordered structure, amorphous alloys do not have magnetocrystalline anisotropy, so they are easy to magnetize; and there are no crystal defects such as dislocations and grain boundaries, so the magnetic permeability and saturation magnetic induction are high; the coercive force is low, The loss is small, and it is an ideal soft magnetic material. Small magnetic devices such as transformers and circuit spike suppressors used in circuits on the market are mostly made of metal soft magnetic materials such as silicon steel and ferrite soft magnetic materials, and their core losses are large. If it is made of amo...
