Definitions
- the invention relates to a soft magnetic nickel-iron alloy.
- the main requirements for the material are a high saturation flux density in order to to achieve high magnetic holding forces with low energy, high permeability, thus a small magnetic field strength, i.e. a low excitation current and a high flux density can be generated in the air gap and so one great attraction to the anchor. Allow low coercivity easy opening of the relay when the excitation current drops.
- the contact surfaces of anchor and yoke must have the smallest possible gap have to a high permeability of the magnetic circuit from yoke and Reach anchor. They must not be damaged by switching the relay as the trigger current of the relay changes.
- nickel-iron alloys are in addition to the desired Alloy elements or deoxidation and / or desulfurization elements like manganese, silicon and aluminum.
- certain minimal additions of oxygen, sulfur, phosphorus, carbon Do not avoid calcium, magnesium, chromium, molybdenum, copper and cobalt, if you compare these alloys with usual because of the cheap cost Wants to manufacture steel mill technology. Under common steel mill technology this involves melting in an open arc furnace with subsequent ladle metallurgy and / or VOD treatment for deoxidation, desulfurization and Degassing understood.
- the block or the continuous casting slab is in one or two steps thermoformed to a thickness of about 4 mm and then Cold-formed to its final thickness, if necessary with intermediate annealing.
- the magnetic Properties deteriorate, as z. B. described in DE 19612556 A1 by adding carbon, nitrogen, oxygen, Sulfur and on non-metallic inclusions.
- Non-metallic contaminants arise due to the required deoxidation and / or desulfurization treatment the melt before pouring.
- the deoxidation and / or Desulfurizing agents are e.g. Oxides of calcium, magnesium or aluminum.
- JP-A 07166281 relates to a magnetic alloy for magnetic heads made of Ni and Fe with additions of Nd, Pr or Sm. Here is the amount of Ni over 78% by weight.
- the object underlying the invention is a soft magnetic Melt iron-nickel alloy that meets the requirements described magnetic properties, corrosion and wear resistance suffices and for a number of preferred applications finds soft magnetic components.
- This task is solved by a soft magnetic iron-nickel alloy with a nickel content of 35 - 65% by mass and one or more of the sides Earth cerium, lanthanum, praseodymium or neodymium as well as melting-related Impurities, the sum of rare earths between 0.003 and 0.05 mass% and the total proportion of rare earths cerium, Lanthanum, praseodymium and neodymium in mass% at least by a factor of 4.4 is greater than the sulfur content in mass%.
- the alloy according to the invention is preferably produced by steelwork technology, ie by melting in an open arc with subsequent ladle metallurgy and / or VOD treatment (vacuum oxidation-decarburization) for deoxidation, desulfurization and degassing. Thereafter, the block or the continuous casting slab is thermoformed in one or two steps up to a thickness of about 4 mm and then cold-formed to final thickness, if necessary with intermediate annealing to adjust the hardness required for the production of parts from this strip. Following the production of parts from this alloy and the annealing of these parts at temperatures between 800 and 1150 ° C., these parts can achieve coercive field strengths of less than 8 A / m.
- Preferred applications of the alloy according to the invention include Relay parts, like yokes and anchors.
- Alloys with a nickel content of less than or equal to 55% by mass all show significantly stronger signs of corrosion on the surface after the end of this alternating climate test than the alloys with nickel contents of more than 75%.
- B. Gehrmann, H. Hattendorf, A. Kolb-Telieps, W. Kramer, W. Möttgen, in Material and Corrosion 48, 535-541 (1997) and thus do not meet the above-described requirements for a relay material in terms of corrosion resistance without additional corrosion-improving measures.
- the magnetic properties required by DIN 17405 on the other hand, were met, as the coercive field strengths Hc given in Table 3 demonstrate (prior art). Composition in mass% Hc in A / m Max.
- the improvement in corrosion behavior according to the invention is surprisingly by desulfurizing the more corrosion-prone nickel-iron alloys with a nickel content of 35 mass% to 65 mass% Cer reached.
- This is preferably done with a mixed metal from the chemical behavior of very similar rare earths cerium and / or lanthanum and / or praseodymium and / or neodymium.
- cerium content in mass% must then be at least a factor of 4.4 higher be than the sulfur content in% by mass in order to completely bind the To reach sulfur through cerium.
- deoxidation also has to be done with cerium or a mixed metal from the rare earths cerium, lanthanum, praseodymium, Neodymium the maximum size values of the sulfidic inclusions in line form SS less than 0.1 or 1.1, the maximum size values of the oxide inclusions in dissolved form OA (aluminum oxides) less than 2.2 or 3.2 or 4.2, the maximum size values of the oxide inclusions in line form OS (silicates) less than 5.2 or 6.2 or 7.2 and the maximum size values of the oxidic Inclusions in globular form OG less than 8.2 or 9.2.
- the magnetic values of permeability and coercive field strength which show the batches E5407 and E0545 according to the invention, are within the usual range of fluctuation of the batches melted according to the prior art, as shown in Table 6.
- Magnetic values of batches according to the prior art (T) and the batches (E) according to the invention measured on samples of 1 mm thickness after annealing from 1080 ° C. for 4 hours under hydrogen and cooling in the oven to 450 ° C.
- the composition of the batches is shown in Table 4.
- Table 8 shows the examination of the content of non-metallic inclusions according to DIN 50602 in various batches according to the prior art (T) and the batches (E) according to the invention.
- material Degree of purity according to DIN 50602 Maximum size value (method M)
- Batch SS OA OS Upper floor Limits 0.1 or 1.1 2.2 or 3.2 or 4.2 5.2 or 6.2 or 7.2 8.2 or 9.2 E5407 k. B. 2.1 k. B. 8.0 E0545 k. B. 2.2 k. B. 8.1 T4392 k. B. 2.2 k. B. 8.0 T5405 k. B. 2.0 k. B. 8.0 T5406 k. B. 2.2 k. B. 8.0 T5477 k. B. 2.1 k. B. 8.1 T5488 k. B. 2.0 k. B. 8.0 T2536 k. B 2.7 k. B kB
- the batch T2536 has a maximum in the form of oxide inclusions in line form Size value of 2.7 (method M). This value is for the use of this Batch too high as material for relay parts. It leads to wear on the Contact surfaces of the relay and has the loss of functionality of the relay result.
- the content of non-metallic inclusions is therefore according to the invention limited as follows:
- the maximum size values according to DIN 50602 of the sulfidic inclusions in Line shapes SS are less than or equal to 0.1 or 1.1, the maximum size values according to DIN 50602 of the oxidized inclusions in dissolved form OA (aluminum oxides) less than or equal to 2.2 or 3.2 or 4.2, the maximum size values according to DIN 50602 the oxide inclusions in line form OS (silicates) less than or equal to 5.2 or 6.2 or 7.2 and the maximum size values according to DIN 50602 of the oxidic inclusions in globular form OG less than or equal to 8.2 or 9.2. All others in table 8 batches listed meet the requirements for the content of non-metallic Inclusions.
