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 achieve high magnetic holding forces with low energy, a high permeability, so that a small magnetic field strength, i.e. a low excitation current and a high flux density can be generated in the air gap and thus a large force of attraction acts on the armature.
- Low coercive field strengths allow the relay to be opened easily when the excitation current drops.
- the contact surfaces of the armature and yoke must have the smallest possible gap in order to achieve a high permeability of the magnetic circuit composed of the yoke and armature. They must not be damaged by switching the relay, since the triggering current of the relay will change. Similar requirements also exist for other molded and stamped parts made of soft magnetic materials.
- the block or the continuous casting slab is then hot-formed in one or two steps to a thickness of approximately 4 mm and then cold-formed to the final thickness, optionally with intermediate annealing.
- the magnetic properties deteriorate, as z. B. has been described in DE 19612556 A1, by admixtures of carbon, nitrogen, oxygen, sulfur and non-metallic inclusions.
- Non-metallic contaminants arise due to the required deoxidation and / or desulfurization treatment of the melt before casting.
- the object on which the invention is based is to melt a soft magnetic iron-nickel alloy which meets the requirements described for the magnetic properties, the corrosion resistance and the wear resistance and which is used for a number of preferred applications in soft magnetic components.
- a soft magnetic iron-nickel alloy with a nickel content of 35 - 65% by mass and one or more of the rare earth elements cerium, lanthanum, praseodymium or neodymium as well as melting-related 4th impurities, the sum of the rare earths between 0.003 and 0.05 mass%.
- the alloy of the invention is preferably made by steel mill technology, i.e. generated by melting in an open arc with subsequent ladle metallurgy and / or VOD treatment for deoxidation, desulfurization and degassing. Thereafter, the block or the continuous casting slab is thermoformed in one or two steps 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 band.
- 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 such as yokes and anchors.
- iron-nickel alloy according to the invention can also be usefully used for the following further applications:
- Alloys with a nickel content of less than or equal to 55% by mass show all significantly stronger signs of corrosion on the surface after the end of this alternating climate test than alloys with a nickel content 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 requirements for a relay material regarding corrosion resistance described above without additional corrosion-improving measures.
- the magnetic properties required by DIN 17405 were met, as the coercive field strengths Hc given in Table 3 demonstrate (prior art).
- the improvement in the corrosion behavior according to the invention is surprisingly achieved by desulfurization of the more corrosion-prone nickel-iron alloys with a nickel content of 35 mass% to 65 mass% with cerium.
- This is preferably carried out with a mixed metal of the rare earths cerium and / or lanthanum and / or praseodymium and / or neodymium, which are very similar in chemical behavior.
- sufficient rare earth atoms must be present. If you start with education e.g. of cerium sulfide with the largest cerium content CeS, this is the case if there are more cerium atoms than sulfur atoms in the alloy.
- the cerium content in mass% must be at least a factor of 4.4 greater than the sulfur content in mass% in order to achieve complete binding of the sulfur by cerium.
- the addition of rare earths can be metered in such a way that the magnetic values of permeability and coercive field strength are within the usual range of fluctuation of the batches melted according to the prior art.
- 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 oxidic inclusions in dissolved form OA aluminum oxides
- the maximum size values of the oxide inclusions in line form OS silicates
- the maximum size values of the oxide inclusions in globular form OG less than 8.2 or 9.2.
- the amount of the cerium content in mass% in the batch E5407 and E0545 according to the invention is more than the factor 4.4 greater than the sulfur content in mass%.
- 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./4 h under hydrogen and cooling in the oven to 450 ° C.
- the composition of the batches is shown in Table 4.
- the only difference between the two batches is the difference in the rare earth content.
- 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.
- the batch T2536 has a maximum size value of 2.7 for the oxide inclusions in line form (method M). This value is too high for the use of this batch as a material for relay parts. It leads to wear on the contact surfaces of the relay and leads to the loss of the functionality of the relay.
- the content of non-metallic inclusions is therefore limited according to the invention as follows:
- the maximum size values according to DIN 50602 of the sulfidic inclusions in line form SS are less than or equal to 0.1 or 1.1, the maximum size values according to DIN 50602 of the oxidic 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 of 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 other batches listed in Table 8 meet the conditions for the content of non-metallic inclusions.
