Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
The core of the present invention is to provide the heat treatment method of a kind of noncrystal anti-DC iron core, it is possible to increase the magnetic of product
Concordance.Another core of the present invention is to provide a kind of noncrystal anti-DC iron core, and the concordance of the magnetic of product is higher.
Refer to the flow chart of the specific embodiment that Fig. 1, Fig. 1 are heat treatment method provided by the present invention.
In a kind of specific embodiment of the heat treatment method of noncrystal anti-DC iron core provided by the present invention, including following step
Rapid:
Step S1: iron core is carried out, according to established standards, balance of classifying.
Wherein, the character of iron core, such as differences such as composition, weight, shapes, annealing parameter is probably different.
Step S2: continuous annealing furnace is preheated.
Step S3: by annealing time and the annealing temperature of the weight set continuous annealing furnace of iron core.
Step S4: put in continuous annealing furnace by the iron core set, continuous annealing furnace keeps annealing temperature to carry out iron core
Annealing.
Wherein, during continuous annealing, need the deviation ensureing actual annealing temperature with the annealing temperature of setting
Less than ± 1 DEG C.
In the heat treatment method of this kind of noncrystal anti-DC iron core, first iron core is classified, then for Different Weight
Iron core set the annealing temperature of continuous annealing furnace and annealing time, enable continuous annealing furnace targetedly iron core to be carried out
Continuous annealing.Continuous annealing in-furnace temperature is the most uniform, it is possible to ensure that the noncrystal anti-DC iron core after annealing has higher
Magnetic consistent degree.
In above-described embodiment, the scope of annealing temperature is specifically as follows 395 DEG C to 403 DEG C, to meet the ferrum of different model
The demand of core.Certainly, annealing temperature can also be set to other values according to practical situation.
In above-described embodiment, annealing time and annealing temperature by the weight set continuous annealing furnace of iron core specifically can wrap
Include:
When the weight of iron core is less than or equal to 10g, sets annealing temperature as 400 DEG C, set annealing time as 2.5 hours；
When the weight of iron core is more than 10g, sets annealing temperature as 400 DEG C, set annealing time as 3.5 hours.
Iron core is divided into two kinds of annealing times according to weight, and keeps identical annealing temperature, it is ensured that annealing quality.
In each embodiment above-mentioned, continuous annealing furnace is preheated and specifically may include that
Step S21: continuous annealing furnace is preheated to 398 DEG C to 400 DEG C.
It is to say, continuous annealing furnace is preheated to about annealing temperature, in order to iron core is putting into continuous annealing furnace rear
Can comparatively fast enter annealed condition.
In above-described embodiment, putting in continuous annealing furnace by the iron core set, continuous annealing furnace keeps annealing temperature to ferrum
After core is annealed, it is also possible to comprise the following steps:
Step S5: iron core is come out of the stove；
Step S6: cool down the iron core after coming out of the stove.
Iron core is made to carry out next step operation again, to ensure safety operation after cooling iron core.
Specifically, the iron core after cooling is come out of the stove is specifically as follows:
Step S61: the iron core after using blower fan cooling to come out of the stove.
This kind of type of cooling is easy and safe to operate.It is of course also possible to use spray cooling or other modes to cool down.
In each embodiment above-mentioned, after cooling down the iron core after coming out of the stove, it is also possible to comprise the following steps:
Step S7: inspect the iron core after coming out of the stove by random samples, detects anti-DC component.
The carrying out of this step can verify the qualification of core annealing, and concrete sampling observation quantity can be according to the total quantity of iron core
Depending on, for example, it is possible to inspect one by random samples in often dish iron core, if be unsatisfactory for production standard need to carry out doing over again or directly as
Waste product, advantageously ensures that safety and the qualification rate of subsequent production.
In each embodiment above-mentioned, iron core is carried out classification balance according to established standards and includes:
Step S11: the iron core of same raw materials, size, shape and weight is put to same leer pan.
Wherein, the identical iron core referring to identical production standard of raw material, iron core by identical band through identical technique
Making, the attribute such as the concrete composition of iron core of generation, toughness, internal structure is identical, is often referred to the iron core of same manufacturer production, phase
Require identical with the usual annealing temperature of the iron core of production standard, it is simple to set annealing temperature.
Step S12: to internal diameter more than during 25mm or cross section to be non-orbicular iron core carry out set by sleeve pipe justifies.Its
In, sleeve pipe can support iron core internal diameter, prevents iron core deformation in annealing process.
Step S13: iron core to be put neatly in leer pan.Wherein, put and neatly specifically can include same leer pan
In iron core distance suitably, to ensure that iron core will not occur crimp in annealing process.
Except above-mentioned heat treatment method, present invention also offers what heat treatment method disclosed in a kind of above-described embodiment was made
Product, the most noncrystal anti-DC iron core, this noncrystal anti-DC iron core makes owing to have employed above-mentioned heat treatment method, product
The concordance of magnetic is higher.The structure of other each several parts of this noncrystal anti-DC iron core refer to prior art, the most no longer
Repeat.
In this specification, each embodiment uses the mode gone forward one by one to describe, and what each embodiment stressed is and other
The difference of embodiment, between each embodiment, identical similar portion sees mutually.
Above noncrystal anti-DC iron core provided by the present invention and heat treatment method thereof are described in detail.Herein
In apply specific case principle and the embodiment of the present invention be set forth, the explanation of above example is only intended to side
Assistant solves method and the core concept thereof of the present invention.It should be pointed out that, for those skilled in the art, not
On the premise of departing from the principle of the invention, it is also possible to the present invention is carried out some improvement and modification, these improve and modification also falls into
