Abstract
The invention discloses a method for manufacturing ferrite cores. The method comprises the steps of A, mixing and sheeting copper oxide and iron trioxide powder; B, firing the combination at the temperature ranging from 1000 DEG C to 1200 DEG C; C, performing gold firing and spray granulation, wherein the granulated granule granularity is 45-60 meshes. According to the method, problems in the prior art are solved, the ferrite cores manufactured through the method are good in working performance, manufacture costs are reduced, and profits are made for enterprises.
Description
Technical field
The present invention relates to a kind of manufacturing process, be specifically related to a kind of manufacture method of FERRITE CORE.
Background technology
The scope of application of FERRITE CORE is very extensive, and in the manufacture process of existing FERRITE CORE, processing cost is high, and the service behaviour of the FERRITE CORE processed simultaneously is relatively poor, and useful life is short, can not meet user demand.
Summary of the invention
The purpose of invention: the present invention, for addressing the above problem, provides a kind of manufacture method of FERRITE CORE of long service life.
Technical scheme: for achieving the above object, the present invention adopts following technical scheme:
A kind of manufacture method of FERRITE CORE, described manufacture method comprises the steps:
A, by the powder mixed pressuring plate of cupric oxide, di-iron trioxide;
B, above-mentioned composition is fired, the temperature of firing is 1000-1200 degree centigrade;
C, finally fire gold and mist projection granulating, the grain graininess of its granulation is the 45-60 order.
In described steps A, the mass ratio of iron oxide and di-iron trioxide powder is 2 ﹕ 1.
Beneficial effect: the produced magnetic core of the described manufacture method of the application of the invention, the favorable working performance of its magnetic core, also reduced processing cost simultaneously, for enterprise has created profit.
