Abstract
The soft magnetic alloy bar has the chemical composition of Al 11-14 wt% and M 0-5 wt% other than Fe, where M is one or several elemetns selected from Si, Mn, Ti, V, Cr, Mo, Nb, Ge and RE, and it is produced through vacuum or gas protected smelting, forging or hot rolling and hot treatment at the temperature below 700 deg. c and with cooling speed controlled in 50-400 deg. c each hr. It is used in fast powerful electromagnet, gyroscope, minuature motor, relay and other similar places and it is superior to available soft magnetic alloy material in use effect and cost.
Description
The present invention relates to a kind of have high magnetic flux density (B), high magnetic permeability (μ), high resistivity (ρ), low-coercivity (Hc), low remanent magnetism (Br), low density of material (d) magnetically soft alloy bar material.
Along with the develop rapidly of automatic technology, require the movement velocity of flash electromagnet further to accelerate, its volume and weight further reduces, and this just requires corresponding soft magnetic material to have higher B value, μ value and ρ value simultaneously, lower Hc value, Br value and d value.At present, the main both at home and abroad requirement of removing to make great efforts to satisfy fast big suction from two aspects.The one, raise the integralization composition and improve Technology for Heating Processing etc. on the basis of alloys such as original soft magnetic material such as 50wt%Ni-Fe, but make little progress, especially the ρ value of material is difficult to significantly improve, Br and d value are difficult to remarkable reduction, and ρ value, Br value and d value influence the major parameter of electromagnet responsiveness just; Be the structure of improving and adjust electromagnet on the other hand.But this method is often attended to one thing and lose sight of another, and has for example improved speed, has but reduced suction, has also reduced the electromechanical conversion efficiency of electromagnet.
The purpose of this invention is to provide a kind of low d magnetically soft alloy bar material of the low Br of the low Hc of the high ρ of the high μ of high B that has, this material can satisfy flash electromagnet and further accelerate responsiveness, can reach the requirement that further reduces volume and weight again, can be widely used in aspects such as gyroscope, electrical micro-machine, relay, the shockproof piston of magnetic fluid, and cost is lower, better effects if.
Above-mentioned purpose of the present invention is achieved in that (M is selected from Si to employing 11-14wt%Al-0～5wt%M-Fe; Mn, Ti, V; Cr; Mo, Nb, Ge; one or more elements of R (rare earth)) chemical composition; adopt vacuum or protective gas melting, by forging and/or be rolled into the alloy bar material of required specification, finished product is by the cooling rate of heat treatment 50 °～400 ℃/hour of controls below 700 ℃.Utilize the increase of alloy of the present invention along with Al content, its electricalresistivity is worth similar increase, saturation induction density Bs, the corresponding rule that reduces of remanent magnetism Br and density d, select proper A l content, utilize in the variation of Al and M constituent content and the alloy order-disorder change magnetocrystalline anisotropy K
l, magnetostriction and saturation magnetization Ms etc. influence rule, take to reduce impurity content and internal stress simultaneously, the evening chemical measure that becomes to grade, reduce coercivity H, improve magnetic permeability μ, this class material is suitable for more emphasizing the electromagnet of fast speed and big suction, also can be used for gyroscope, electrical micro-machine relay, the application of aspects such as the shockproof piston of magnetic fluid.
Alloy bar material combination property of the present invention is better than alloy bar materials such as original soft magnetism bar material such as 50%wt%Ni-Fe, and especially the ρ value increases substantially, and Br value and d value reduce significantly, and these parameters have determined the motion fast speed of electromagnet just.Because the ρ value is high, electromagnet is little at the energising eddy current that moment produced, a little less than the counter magnetic field, and the electromagnet quick action; Because the d value is low, the quality of equal volume is little, and under same suction, the acceleration of action just increases; Because the Br value is low, the rate of release of electromagnet is accelerated, and its acting force of the spring also can reduce; Because the Hc value is low, electromagnet is under the demagnetizing field effect of certain working gas gap and non-working-gap, and it is lower that the Br value can become, and more helps the release of electromagnet; Because the B value is higher, under same sectional area condition, the suction of electromagnet just further increases, and just can further reduce the volume and weight of electromagnet.
Realize best way of the present invention, below for several examples: embodiment 1
