Abstract
Способ определения магнитной восприимчивости железорудного материала в потоке, включающий измерение выходных сигналов двух неидентичных по длине индукционных зондов, установленных на различных расстояниях от поверхности потока железорудного материала, соответствующих максимумам их геометрических факторов, отличающийся тем, что, с целью повышения точности, предварительно устанавливают зонды над моделью плоского магнитного полупространства и выравнивают сигналы индукционных зондов, после измерения выходных сигналов индукционных зондов при действии на них контролируемого потока железорудного материала определяют значение толщины слоя железорудного материала из условия выполнения равенстваI(1-G(d/I)/G(d/I))=I(1-G(d/I)/G(d/I))а магнитную восприимчивость железорудного материала определяют по полученному значению правой и левой частей равенства,где d=h+d, d=h+d;G(d/I)=((h/I+1)-0,5)/32(h/I+1)+0,25);G(d/I)=G(0/I), i=1,2;I, I- значение сигналов первого и второго индукционных зондов;h - толщина слоя железорудного материала;d, d- расстояние, соответствующие максимумам геометрических факторов первого и второго индукционных зондов.The method for determining the magnetic susceptibility of iron ore material in a stream, including measuring the output signals of two nonidentical lengthwise induction probes installed at different distances from the flow surface of the iron ore material, corresponding to the maxima of their geometric factors, characterized in that the probes model of flat magnetic half-space and align the signals of the induction probes, after measuring the output signals of the induction onds under the action of a controlled flow of iron ore material on them determine the value of the thickness of the layer of iron ore material from the condition of equality I (1-G (d / I) / G (d / I)) = I (1-G (d / I) / G ( d / I)) and the magnetic susceptibility of iron ore material is determined by the obtained value of the right and left sides of the equality, where d = h + d, d = h + d; G (d / I) = ((h / I + 1) -0 , 5) / 32 (h / I + 1) +0.25); G (d / I) = G (0 / I), i = 1.2; I, I is the value of the signals of the first and second induction probes; h is the layer thickness of the iron ore material; d, d is the distance corresponding to the maxima of the geometric factors of the first and second indukts ion probes.
