Определение электромагнитных параметров трубы с учетом ее нагрева

Abstract

The paper considers a temperature coefficient a calculation technique with application of a new multiparameter method of relative magnetic permeability \ir, electric conductivity о and temperature t determination for a pipe in the temperature range of 20°C< t <180°C and within the \ir range from 50 through 1000. The basic relationships for the electromagnetic parameters of ferromagnetic pipes are derived along with expression for the temperature at which the parameters are determined.
