Description
Насто щее изобретение относитс к способам определени магнитных свойств электротехнической стали в листах неограниченных размеров на переменном токе, основанным на измерении величины индукци при различных значени х намагничивающего тока.The present invention relates to methods for determining the magnetic properties of electrical steel in sheets of unlimited size on an alternating current, based on measuring the magnitude of the induction at different values of the magnetizing current.
Предлагаемый способ отличаетс от известных тем, что при испытани х измер ют отношение потока индукции при заданном напр жении магнитного пол образца к потоку насыщени того же образца, а затем по этому отношению и по известному значению индукции насыщени дл данной марки стали определ ют действительную величину индукции в -образце.The proposed method differs from the known ones by testing the ratio of the induction flux at a given voltage of the magnetic field of the sample to the saturation flux of the same sample, and then the actual induction value is determined from this ratio and the known saturation induction value for this steel grade. in the sample.
При применении такого способа отпадает необходимость определени размеров исследуемых листов.When using this method, there is no need to determine the size of the test sheets.
На чертеже изображена припцйпиальна схема устройства дл определени магнитных свойств электротехнической стали по предлагаемому способу.The drawing shows a diagram of the device for determining the magnetic properties of electrical steel according to the proposed method.
Процесс измерени заключаетс в определении с помощью логометра / магнитоэлектрической системы отнощени значени потока индукции при заданном поле к потоку индукции насыщени того же участка исследуемого листа или ленты.The measurement process consists in determining, using a logometer / magnetoelectric system, the ratio of the value of the induction flux at a given field to the saturation induction flux of the same portion of the sheet or tape under study.
Измер емый участок 2 исследуемого рулона нли ленты электротехнической стали перемагничиваетс циклически по симметричной петле, в вершине которой индукци достаточпо близка к индукции насыщени даниого материала. Одна из катущек логометра / замыкаетс через выпр митель 3 со строго линейной характеристикой на измерительную катушку 4. Друга катушка логометра замыкаетс на измерительную катушку 5 через фазоупразл емый коммутатор 6 любой системы (механический , электронный и т. п.). Катушка 7, размещенна вблизи поверхности листа, действует как магнитный потенциометр и управл етс коммутатором 8, действующим синхронно с коммутатором 6.Measurement section 2 of the studied roll of electrical steel tape reversal is reversal cyclically along a symmetric loop, at the apex of which the induction is sufficiently close to the induction of saturation of the alloy material. One of the gauge coils / closes through the rectifier 3 with a strictly linear response to the measuring coil 4. Another gauge coil is closed to the measuring coil 5 through the phase expansion switch 6 of any system (mechanical, electronic, etc.). The coil 7, located near the surface of the sheet, acts as a magnetic potentiometer and is controlled by a switch 8 acting synchronously with the switch 6.
