Description
Изобретение относитс к неразрушав щему контропю глубины упрочненного сло стальных изделий, например, глубины цементированного ело , глубины отбепа . отливок КЗ серого чугуна и т.п. и мсжет быть использовано на машиностроительных предпри ти х.The invention relates to the non-destructive contour of the depth of a hardened layer of steel products, for example, the depth of the cemented body, the depth of the bleach. gray iron castings, etc. and can be used in machine building plants.
Известен электромагнитный преобразователь , содержащий П-образный магнитопровод , размещенные на стержн х маг нитопровода возбуждающую и измерительную обмотки 1 3.A known electromagnetic transducer containing an U-shaped magnetic circuit, which excites and measuring windings 1 3 placed on the rods of the magnetic conductor.
Недостатком преобразовател вл етс мала чувствительность к неоднородноот м контролируемого материала.The disadvantage of the transducer is its low sensitivity to inhomogeneities of the material being monitored.
Наиболее близким к изобретению &л етс электромагнитный преобразователь дл контрол глубины упрочненного сло , содержащий Ш-образный магнитопровод, размещенную на среднем стержне возбуждающую обмотку и две встречно-включенные измерительные обмотки, размещенные на крайних стержн х. Стержни магкитопровода имеют одинаковое сечение, аThe closest to the invention is an electromagnetic transducer for monitoring the depth of the hardened layer, comprising an Ш-shaped magnetic circuit, an exciting winding placed on the middle rod, and two counter-connected measuring windings placed on the outermost rods. The rods of the magnetic conduit have the same cross section, and
крайние стержни одинаково удалены от . среднего стержн 2 .extreme rods equally spaced from. middle rod 2.
Недостатком преобразовател Явл етс низка чувствительность к глубине поверхностного упрочненного сло контролируемого издели .A disadvantage of the transducer is the low sensitivity to the depth of the surface hardened layer of the monitored product.
Цепь изобретени - повышение чувствительности преобразовател .The circuit of the invention is to increase the sensitivity of the transducer.
Указанна цель достигаетс за счет того, что в электромагнитном преобразователе дл контрол глубины упрочненного сло , содержащем Ш-образный магнитопровод , размещенную на среднем стержне возбуждающую обмотку и две встречно- включенные измерительные обмотки, размещенные на крайних стержн х, сечение э одного из крайних стержней .This goal is achieved due to the fact that in an electromagnetic transducer to control the depth of the hardened layer, containing an-shaped magnetic circuit, the exciting winding is placed on the middle rod, and two oppositely connected measuring windings placed on the extreme rods are section of one of the extreme rods.
