Abstract
The invention relates to a nano-phase material silicon steel sheet which can substitute a practically-used silicon steel sheet. with high magnetic conductivity, low coercive rate, great resistivity, the nano-phase material silicon steel sheet has less hysteresis and eddy loss, better magnetic conductivity and lower attrition rate after rolling and annealing and effectively improves the qualities of a motor and a transformer and decreases the costs.
Description
Technical field:
The invention belongs to novel magnetic material field, particularly a kind of silicon steel sheet that contains nano-phase material.
Technical background:
Transformer is to utilize electromagnetic induction to realize transmitting to another circuit from a circuit a kind of electrical equipment of electric energy or transmission signals, it is electrical energy transfer or as the critical elements of signal transmission, transformer can be transformed to a kind of AC energy of voltage the AC energy of the another kind of voltage of same frequency.The critical elements of transformer is an iron core and two or more windings that are enclosed within on the iron core.
Iron core is a magnetic circuit part important in the transformer, and higher by silicon content usually, thickness is 0.35,0.3,0.27mm, and the surface scribbles the hot rolling of insulating varnish or cold rolling silicon steel sheet closed assembly or coiling and forms.
Iron core is divided into core limb and transverse sheet two parts, and core limb is with winding; Transverse sheet plays the closed magnetic circuit effect, and coiling can become different shape, annular, rectangle, ellipse.
The transformer core material price of using is higher at present, and the magnetic flux that coil produces increases the loss of transformer at the induced potential that iron core flows and produces.And make heating unshakable in one's determination, the temperature of transformer increases, and consequent " iron loss " is bigger, has reduced power output, has reduced efficient again.
The invention provides a kind of silicon steel sheet of nano-phase material, substitute the silicon steel sheet that uses at present, overcome with upper iron core price height, conductivity height, defective that resistivity is low, make the loss of transformer little, temperature reduces, and has improved the efficient of transformer, has reached energy-conservation effect.
The object of the present invention is achieved like this: adding siliceous nano-phase material in the steel disc of Overheating Treatment hot rolled strip or cold-rolled strip, make it substitute the silicon steel sheet that uses at present, reduced the conductivity of steel disc effectively, increased resistivity, reduced the caused eddy current loss of flux change, transformer core thickness is that the product of the present invention of 0.27-0.35mm builds up or reels and forms.Isolate shape invariance unshakable in one's determination between sheet with insulating varnish.
The magnetic density of product of the present invention can reach the standard of grain orientation silicon steel sheet: (the GS Gauss of unit)
Iron plate B value=6000-8000
Low silicon chip B value=9000--11000
There is not orientation silicon steel sheet B value=12000-16000
Grain orientation silicon steel sheet B value=15000-20000
Silicon content: 1.0-4.5%, phosphorus content is lower than 0.03%, does not contain other objectionable impurities.
With metal oxide nanoization, inorganic material nanometer successful Application is in the modification of steel disc, general common magnetisable material all belongs to the aggregate of magnetic region, when particle size little to can't distinguish its magnetic region the time, promptly form the magnetisable material of single magnetic field, when therefore magnetic material is made ultramicron or film, will become the excellent magnetism material.
Concrete enforcement: each composition by the proportioning of better quality is: 1. solid content is that 50% water-borne acrylic resin 35-50, solid content are 50% water-compatible amino resin 5-35, nano-phase material organosilicon 25-40. is one or more the pro rata mixtures in the raw material such as the titanium dioxide of average grain diameter below 10mm, blanc fixe, kaolin, mica powder, calcium carbonate, talcum powder, barium sulfate, magnesium oxide 2., and this amounts of components accounts for the 5-40% of total amount.3. auxiliary component: one or more in defoamer, dispersant, stabilizer, the antifreeze, addition account for the 0-15% of gross mass.4. water and water-miscible organic solvent are formed, and its consumption adds the 5-75% that accounts for gross mass by the viscosity requirement.
The present invention has taken all factors into consideration the wherein consumption and the proportioning of each combination, and it is reasonable to make it to be tending towards to greatest extent
Preparation: add 1. component and stir and add in mixing kettle, 2. component is disperseed to add 3. 4. again with homogenizer component is got product through sand mill
Dispensing viscosity is 25s-45s
The present invention connects in the coating device at the silicon steel sheet tandem rolling and uses, in furnace temperature is 600 ℃--800 ℃. and 280 ℃ of plate surface temperatures--350 ℃, the steel disc translational speed is that 60m/min 45s drying time obtains the smooth thickness 1.2um-3um of outward appearance light, interface resistance is worth 1600 Ω, adhesive force, all satisfactory nano-phase material thin layer of rustless property magnetic shield performance silicon steel sheet.
The present invention does not contain chromate and other harmful components, do not contain environment is polluted, safe and reliable, have excellent electrical insulating property, surface-brightening is smooth, all satisfies the quality requirement of silicon steel sheet as purposes such as motor, transformers on performances such as resistance to water, antirust, high temperature resistant, adhesive force.
Claims (3)
1. the silicon steel sheet of a nano-phase material is characterized in that very strong materialization effect takes place for the ultramicronized characteristic of external application nano silicon oxide and nano-organosilicon and steel band not siliceous or that silicon content is few, make the magnetic permeability height, rectify that stupid rate is low, resistance coefficient is big, thereby magnetic hysteresis loss and eddy current loss are little, rolling after the annealing magnetic permeability is better, the proportion of goods damageds are lower.
