Description
Technical field
The present invention relates to technical field of ferrous metallurgy, relate in particular to a kind of stainless steel magnetic valve core iron.
Background technology
Soft magnetic materials is the important materials of widespread use in power industry and electronic industry.In power industry, from the generation (generator) of electric energy, transmission (transformer), to the process of utilization (electric motor), soft magnetic materials plays a part energy transformation.In electronic industry, from communication, control automatically, broadcast, TV and film, electronic computation technology to microwave technology, soft magnetic materials plays the effects such as conversion, transmission and the storage of information.The performance of soft magnetic materials is often because application is different, but conventionally wishes that the magnetic permeability μ of material wants high, and coercivity H and loss Pc are low.
Soft magnetic materials mainly contains the crystalline material take metal soft magnetic material and soft magnetic ferrites as representative, the nano-crystal soft magnetic alloy that amorphous soft magnetic alloy and development in recent years are got up etc.The interelectric exchange interaction of metal soft magnetic material is strong, thereby saturation induction density Bs is high, Curie temperature is high.But because its resistivity is low, the large and skin effect of eddy-current loss, is only suitable for using under low frequency.Soft magnetic ferrites are ferrimagnetisms, and interelectric exchange interaction is indirectly, and two groups of neighbour's time grid magnetic moment direction are contrary, and therefore saturation induction density Bs is low, Curie temperature is low.But its resistivity is high, be particularly suitable for applying under high frequency.Though the Bs of amorphous, nanocrystalline material is more or less the same with metal soft magnetic material, its coercivity H is much smaller.Compared with crystalline material, amorphous material has high strength, high corrosion resistance, high-magnetostriction coefficient, high electromechanical coupling factor and the characteristic of high resistivity conventionally.
Along with the fast development of automatic control technology, magnetic valve is not only required to higher dynamic magnetic performance with core iron, and require to have good corrosion resistance nature.Conventional soft magnetic materials is difficult to meet above-mentioned requirements at present.Although pure iron has higher saturation induction density (2.1T) and initial permeability (7500), low coercive force (56A/m).But (130 μ Ω mm) is lower for its resistivity, and frequency applications power loss is high, is only applicable to low frequency.But also there is corrosion-prone problem.Although silicon steel resistivity, than pure iron high (400 μ Ω mm), exists corrosion-prone problem equally, for guaranteeing that its solidity to corrosion just must be electroplated, this has not only increased production cost but also have environmental pollution problem.Although soft magnetic ferrite resistivity is high, corrosion-resistant, its saturation induction density is too low, is not suitable for the controlling elementss such as magnetic valve.Although conventional stainless steel has good corrosion resistance nature, its magnetic property can not meet the requirement of magnetic valve core iron.Therefore develop anti-corrosion soft magnetic materials very important.
