Functional extrapolation of the mass-operational characteristic of magnetophoresis as a basis for a precision method of monitoring ferroparticles

Justification of Characteristics of Operational-Functional Magnetic Control of Ferroprimes

“…Since ferroimpurities in the main mass have ferromagnetic properties, method of their magnetic control, assuming separation of ferro impurities from a sample of the analyzed medium and possible subsequent analysis, for example, microscopy (in ferrography [3][4][5][6]), is preferable. At the same time, to carry out objective monitoring, in particular, determining the content of ferroimpurities (as a rule, highly dispersed), a necessary condition for such monitoring is to conduct multiple extraction operations [1,7] (unlike ferrography, where it is assumed a single pass of the sample through the magnetophoresis zone). The question of the recommended (for the achievement of the necessary accuracy of control) multiplicity of magnetic control operations, or rather, validity of the very statement of this question and search for acceptable solutions was specifically discussed in [7].…”

“…Control of "always present" in various environments of metal impurities (consisting in most cases of ferrous impurities, mainly products of wear, processing and corrosion of elements of steel equipment) is one of the key tasks of controlling quality of environments [1,2].…”

Two-exponential model of ferroimpurities extraction during magnetic inspection of these impurities content in various media

“…At the same time, along with numerous data [1][2][3][4], which showed the specified correspondence, a number of data revealed, which obviously do not correspond to the regularity (1). Among them -the data of polyoperational magnetophoresis, obtained for the molding mixture, sand sugar, feldspar samples.…”

“…Such control is performed via various methods (depending on specific media), including the polyoperational magnetophoresis method [1][2][3][4]. In particular, in this case a sample of the liquid media is passed through a sectional magnetic analyzer with the number of sections-operations n or n operations of "magnetic scanning" of a granular medium thin layer [1,2].…”

“…In particular, in this case a sample of the liquid media is passed through a sectional magnetic analyzer with the number of sections-operations n or n operations of "magnetic scanning" of a granular medium thin layer [1,2]. This approach leads to one of the conceptual provisions of the physical control model of this type: the analytic form appears of the decrease in mass m of ferroimpurities, extracted from the sample while operations, desirable for the extrapolation analysis, and this form is usually an exponential one [1][2][3][4]:…”
