Abstract
Способ определения кажущейся магнитной восприимчивости железорудного материала на конвейере, включающий измерение текущих значений ЭДС двух индукционных зондов, расположенных под поверхностью железорудного материала на расстояниях максимумов их геометрических факторов, и определение градуировочной зависимости информативного параметра от кажущейся магнитной восприимчивости железорудного материала, отличающийся тем, что, с целью повышения точности при изменении толщины слоя железорудного материала, измеряют отношение ЭДС первого и второго индукционных зондов от действия магнитного полупространства и отношении текущих значений ЭДС индукционных зондов для контролируемого слоя железорудного материала и определяют информативный параметр одного из индукционных зондов из следующих соотношений:где F(γ) = γ(1-K)/(γ-Kγ);F(γ) = γ(1-K)/(γ-Kγ);- информативные параметры первого и второго индукционных зондов;Еи Е- текущие значения ЭДС первого и второго индукционных зондов от действия контролируемого слоя железорудного материала;Еи Е- значения ЭДС первого и второго индукционных зондов от действия магнитного полупространства.The method of determining the apparent magnetic susceptibility of iron ore material on the conveyor, including measuring the current EMF values of two induction probes located under the surface of the iron ore material at distances of maxima of their geometric factors, and determining the calibration dependence of the informative parameter on the apparent magnetic susceptibility of iron ore material, characterized in that the purpose of increasing accuracy when changing the thickness of the layer of iron ore material, measure the ratio of the emf and the second induction probes from the magnetic half-space and the ratio of the current values of the EMF of the induction probes for the controlled layer of iron ore material and determine the informative parameter of one of the induction probes from the following relations: where F (γ) = γ (1-K) / (γ-Kγ) ; F (γ) = γ (1-K) / (γ-Kγ); - informative parameters of the first and second induction probes; Eu E - current values of the EMF of the first and second induction probes from the action of a controlled layer of iron ore material; Eu E - values EMF of the first and second induction probe to the action of a magnetic half-space.
