Definitions
- the invention relates to a hot strip for producing an electric sheet and a method for this purpose.
- Materials for electrical sheets are z. B. from DE 101 53 234 A1 or DE 601 08 980 T2. They usually consist of an iron-silicon or iron-silicon-aluminum alloy, whereby a distinction is made between grain-oriented (KO) and non-grain-oriented (NO) electrical sheets and these are used for different applications.
- anisotropic Depend on the direction of stress, referred to as anisotropic. If the properties are equivalent in all stress directions, this is called isotropic materials.
- the anisotropy of the magnetic properties of electrical steel is based on the crystal anisotropy of the iron. Iron and its alloys crystallize in a cubic structure.
- the cube edge direction is the most magnetizable direction [100].
- the direction of the space diagonal [111] in the cube is the most magnetically unfavorable direction.
- non-grain oriented electrical steel For applications in electrical engineering, in which the magnetic flux is set in any particular direction and therefore equally good magnetic properties in all directions are required, one usually produces electrical steel strip with isotropic properties as possible, which is referred to as non-grain oriented (NO) electrical steel.
- NO non-grain oriented
- the ideal structure for a non-grain oriented electrical steel strip is a polycrystalline structure with grain sizes between 20 [im and 200 pm, with the crystallites aligned randomly in the plane of the sheet with the surface (100).
- the magnetic properties of real non-oriented electrical steel are in the Sheet metal to a small extent dependent on the magnetization direction.
- the loss differences between the longitudinal and transverse directions are only max. 10%.
- the expression of a sufficient isotropy of the magnetic properties in non-grain-oriented electrical steel is substantially influenced by the design of the hot forming, cold forming and final annealing.
- Orientation of the crystallites (crystallographic texture), which is called grain-oriented (KO) electrical steel.
- the uniform orientation of the crystallites causes a strong anisotropic behavior of the electrical steel.
- an efficient grain growth selection is carried out by the complex production. His grains (crystallites), with a slight misalignment in the final annealed material, show an almost ideal texture, the Goss texture named after its inventor.
- a cube edge points in the rolling direction a surface diagonal points across the rolling direction. The deviation of the cube edge to the rolling direction is usually up to 7 ° for the standard material and up to 3 ° for the high-permeability material.
- the size of the grains is several millimeters to centimeters.
- the magnetic properties in the electrical steel are substantially due to a high degree of purity, the content of silicon and aluminum (up to about 4 mass%), small amounts of other alloying elements, such.
- the common sheet thicknesses are in the range well below 1 mm, z. B. at 0.18 or 0.35 mm.
- non-grain oriented material is as isotropic as possible in the sheet plane
- Magnetization direction increases the Ummagnetleiterswe and the relative permeability. With this textured material can therefore be compared with non-grain oriented Materials transformers that produce a lower efficiency at higher efficiency
- the material known from DE 101 53 234 A1 for a non-grain-oriented electrical steel sheet has an alloy composition with C ⁇ 0.02%, Mn-1, 2%, Si 0, 1-4.4% and Al 0, 1-4, 4% up.
- a disadvantage of the known material are each with max. 4.4% relatively low Si and Al contents, which in many applications, the magnetic permeability is not high enough and the magnetization loss is sufficiently low, which adversely affects the efficiency of electric machines and thus their efficiency.
- Si and Al content With increasing Si and Al content, the electrical resistance of the steel increases. As a result, the induced eddy currents and thus the core losses are reduced.
- Casting powder can be from an AI content of Do not use melt of more than approx. 2% since aluminum interacts with the oxygen bound in the casting powder to form aluminum oxides (see above).
- the object of the invention is to provide a hot strip for the production of an electrical sheet, with which in comparison to known electric sheets significantly improved magnetic properties, in particular a higher magnetic permeability, can be achieved.
- Another object is an improved and less expensive one
- the hot strip according to the invention has the following alloy composition in% by weight:
- Improvement of the hot rolling properties contribute, since the forming nitrides (BN, ZrN) or carbides (ZrC) attach to the grain boundaries and sliding at high
- the minimum content for B should be 0.001% and for Zr should be 0.05%. It is also advantageous that the hot crack susceptibility is significantly reduced by these additions.
- the ductility at room temperature can advantageously be improved without significantly affecting the magnetic properties.
- the hot strip with the alloy composition according to the invention is characterized by significantly improved magnetic properties, in particular by a significantly higher magnetic permeability, through which the field of application of this material under energetic and economic aspects can be significantly increased.
- the thickness of the layer may be affected by the temperature and time of annealing.
- this scale layer should not have a thickness of 100 ⁇ , better ⁇
- a method is used according to the invention, in which the melt flow-smoothed and bend-free cast in a horizontal strip casting in a range between 6 and 30 mm thickness and then hot strip with a degree of deformation of at least 50% in thicknesses rolled from 0.9 to 6.0 mm.
- an annealing process at 800 to 1200 ° C may be necessary.
- the high degree of deformation is also necessary to destroy the microstructure, especially in high-Al alloys and thus to reduce the grains (grain refining).
- the hot strip can also be used advantageously as an end product in electromagnetic fields of application.
- an additional annealing process is necessary so that the grains can align. This process, which involves annealing between 800 and 1200 ° C, can be continuous or discontinuous, lasting up to 30 minutes.
- the alloy composition according to the invention it is possible with the alloy composition according to the invention to produce both grain-oriented (KO) and non-grain-oriented (NO) electrical tapes, depending on the specification.
- the hot strip after a reheating annealing process (possibly in a decarburizing atmosphere) and thus adjust final thicknesses of up to 0.1 mm.
- the annealing after cold rolling should be done at temperatures of 700 and 900 ° C for a maximum of 10 minutes or for KO electrical tapes for several hours in a comparable temperature window.
- a decarburizing atmosphere is advantageous because it reduces the carbon content in the belt (mainly at the periphery). This leads to an improvement of the magnetic properties, since fewer defects occur in the material, which are caused for example by the carbon atoms.
- the advantage of the proposed method is the fact that when using a horizontal strip casting Macroseiger Heidelberg and blowholes can be largely avoided due to very homogeneous cooling conditions in the horizontal strip casting. Since no casting powder is used in these plants, eliminating the
- the length of the conveyor belt is selected so that at the end of the conveyor belt before its deflection, the Vorband is largely solidified.
- a homogenization zone which is used for temperature compensation and possible stress relief.
- Rolling from pre-strip to hot strip can be done either in-line or separately off-line.
- the pre-strip Before off-line rolling, the pre-strip may be either directly hot-rolled or sliced into sheets after manufacture prior to cooling. The strip or sheet material is then reheated after a possible cooling and unwound for the off T line rolling or rewarmed and rolled as a panel.
- Strip casting plant 1 consisting of a circulating conveyor belt 2 and two deflection rollers 3, 3 '. Evident is also a side seal 4, which prevents the discontinued melt 5 can flow down to the right and left of the conveyor belt 2.
- the melt 5 is transported by means of a pan 6 to the strip casting plant 1 and flows through an opening 7 provided in the bottom into a feed vessel 8.
- This feed vessel 8 is designed as an overflow vessel. Not shown are the facilities for intensive cooling of the underside of the upper strand of the conveyor belt 2 and the complete enclosure of the strip casting 1 with appropriate inert gas atmosphere.
- a homogenization zone 10 at. This consists of a thermally insulated housing 11 and a roller table, not shown here.
- the then following first stand 12 is formed either only as a pure drive unit, possibly with a small puncture or as a roll unit with a predetermined puncture.
- Subsequent scaffolding 14 instead, with the first three scaffolds 15, 15 ', 15 "effect the actual stitch reduction, while the last frame 16 is formed as a smoothing mill.
- Reel temperature is cooled down.
- a pair of scissors 20 is arranged between the end of the cooling section 17 and reel 19, 19 '.
- This scissors 20 has the task of dividing the hot strip 18 transversely as soon as one of the two reels 19, 19 'is fully wound.
- the beginning of the subsequent hot strip 18 is then passed to the second vacant reel 19, 19 '. This ensures that the tape tension is maintained over the entire tape length. This is particularly important in the production of thin hot strips.
