Изобретение относитс к средствам электромагнитного неразрушающего контрол материалов и изделий и может быть использовано дл контрол качества термообработки ферромагнитных прот женных изделий.The invention relates to electromagnetic non-destructive testing of materials and products and can be used to control the quality of heat treatment of ferromagnetic extended products.
По авт. св. № 278181 известен способ магнитного контрол прот женных стальных изделий , заключающийс в том, что качество термообработки определ ют путем измерени пол остаточной намагниченности контролируемого издели .By bus. St. No. 278181, a method of magnetic control of extended steel products is known, which means that the quality of heat treatment is determined by measuring the field of residual magnetization of the product being tested.
Однако достоверность контрол известным способом недостаточна, так как параметры пол неоднозначно онредел ют структуру термообработанного издели по всей его длине.However, the reliability of the control in a known manner is insufficient, since the floor parameters ambiguously determine the structure of the heat-treated product along its entire length.
Цель изобретени - повысить достоверность контрол качества термообработки.The purpose of the invention is to improve the reliability of heat treatment quality control.
Это достигаетс тем, что определ ют погонный градиент коэрцитивной силы и по отклонению от его экстремальных значений суд т о результатах контрол .This is achieved by determining the linear gradient of the coercive force and judging the results of the control from the deviation from its extreme values.
Термообработанное изделие намагничивают по предельной петле гистерезиса, предварительно разместив его на участки по всей длине, на которых производ т измерени коэрцитивной силы. Затем онредел ют погонный градиент коэрцитивной силы по результатам ее измерений. Получив экстремальные значени погонного градиента, определ ют отклонени от него по каждому участку издели и по 0 этим отклонени м суд т о перегреве или недогреве участков длинномерных изделий.The heat-treated product is magnetized along the limiting hysteresis loop, preliminarily placing it into sections along the entire length over which the coercive force is measured. Then they determine the linear gradient of the coercive force by the results of its measurements. Having obtained the extreme values of the linear gradient, deviations from it are determined for each section of the product, and by these 0 deviations, overheating or underheating of sections of long products is judged.
Предмет изобретени Subject invention
Снособ магнитного контрол прот женных 5 стальных изделий но авт. св. 278181, отличающийс тем, что, с целью повыщени достоверности контрол качества термообработки , определ ют погонный градиент коэрцитивной силы -И ио отклонению от его экст0 ремальных значений суд т о результатах контрол .Magnetic inspection method for 5 steel products but auth. St. 278181, characterized in that, in order to increase the reliability of the heat treatment quality control, the linear gradient of the coercive force — I and its deviation from its extremal values — is determined on the results of the control.
