The composite multilayered high-temperature resisting magnetic steel is composed of at least one layer of samarium cobalt magnetic steel and at least one layer of neodymium iron boron magnetic steel. The samarium cobalt magnetic steel is stuck to the neodymium iron boron magnetic steel in the direction with the same orientation degree through a bonding agent. According to the composite multilayered high-temperature resisting magnetic steel, the requirements of various types of equipment can be met; the composite multilayered high-temperature resisting magnetic steel is adapted to a complicated working environment, the service life of the magnetic steel is prolonged and the application range of the magnetic steel is enlarged.
Description
Technical field
The utility model relates to the high temperature resistant magnet steel of a kind of composite multi-layer, belongs to permanent magnetic steel application.
Background technology
As the Nd-Fe-B magnet steel of third generation permanent-magnet material, there is higher magnetic energy product and coercivity, the feature of high-energy-density.But with respect to second generation permanent-magnet material SmCo magnet steel, its resistance to elevated temperatures is poor.Along with the development of modern technologies, the application of permanent-magnet material under high-temperature field is urgent gradually, requires permanent-magnet material at high temperature to show fine magnetic property, and SmCo magnet steel reenters people's sight line, but himself magnetic energy product is on the low side, and application is restricted.Tradition research method is that research improves the coercivity of Nd-Fe-B magnet steel or the magnetic energy product of SmCo magnet steel, but due to self material, makes little progress, and R&D costs significantly improve, and causes a large amount of unnecessary wastings of resources.
Utility model content
Technical problem to be solved in the utility model is to provide the high temperature resistant magnet steel of a kind of composite multi-layer, and the binding agent between SmCo magnet steel and Nd-Fe-B magnet steel with low thermal conductance or endothermic character bonds together, and binding agent plays the effect of bonding and heat absorption.When arranging when bonding according to a graded between SmCo magnet steel and Nd-Fe-B magnet steel, can avoid the set of the eddy current effect that single magnet produces, weakened the intensity of opposing magnetic field, avoided the reduction of magnet assembly magnetic property.SmCo magnet steel and Nd-Fe-B magnet steel are bonded together use, and the good heatproof characteristic of SmCo magnet steel can effectively be protected, and reduce the hot demagnetize of Nd-Fe-B magnet steel.Under hot environment, give full play to the high energy product of Nd-Fe-B magnet steel, the advantage of high-energy-density.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of composite multi-layer is high temperature resistant magnet steel, described composite multi-layer is high temperature resistant magnet steel by one deck SmCo magnet steel at least and at least one deck Nd-Fe-B magnet steel form, described SmCo magnet steel bonds together by binding agent and described Nd-Fe-B magnet steel with degree of orientation equidirectional.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, when SmCo magnet steel is during more than one deck, between described SmCo magnet steel, with degree of orientation equidirectional, by binding agent, bond together.
Further, when Nd-Fe-B magnet steel is during more than one deck, between described Nd-Fe-B magnet steel, with degree of orientation equidirectional, by binding agent, bond together.
Further, the high temperature resistant magnet steel of described composite multi-layer is comprised of one deck SmCo magnet steel and one deck Nd-Fe-B magnet steel.
The beneficial effects of the utility model are:
The good effect that compared with the prior art the utility model has is, by will be at least one deck SmCo magnet steel and at least one deck Nd-Fe-B magnet steel with binding agent, stick together, greatly reduce the eddy current that magnet steel produces in equipment running process, SmCo magnet steel has higher temperature tolerance, in high temperature installation and equipment operation process, can effectively resist high temperature and opposing magnetic field, reduce the hot demagnetize of magnet steel, the working environment of Nd-Fe-B magnet steel is improved, can effectively bring into play high energy product, the advantage of high-energy-density, the compound use of two kinds of magnet steel, also can effectively reduce dysprosium, the use amount of your rare earth such as samarium and strategy metal cobalt, thereby reduce costs, reduce the wasting of resources.By the combination of different trade mark SmCo magnet steel and Nd-Fe-B magnet steel, apply in addition, can meet the demand of various distinct devices, adapt to complex work environment, improve magnet steel service life, expand the range of application of magnet steel.

Fig. 1 is the structural representation of the high temperature resistant magnet steel of a kind of composite multi-layer of the utility model;
In accompanying drawing, the list of parts of each label representative is as follows:
1, SmCo magnet steel, 2, Nd-Fe-B magnet steel, 3, binding agent.
The specific embodiment
Below principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
Embodiment 1
As shown in Figure 1, a kind of composite multi-layer is high temperature resistant magnet steel, described composite multi-layer is high temperature resistant magnet steel by one deck SmCo magnet steel 1 at least and at least one deck Nd-Fe-B magnet steel 2 form, described SmCo magnet steel 1 bonds together by binding agent 3 and described Nd-Fe-B magnet steel 2 with degree of orientation equidirectional.
Further, the high temperature resistant magnet steel of described composite multi-layer is comprised of one deck SmCo magnet steel 1 and one deck Nd-Fe-B magnet steel 2.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
