“…In addition, its thermal expansion coefficient is close to the coefficient of ceramics which was used. This combination allows to immerse these inserts in mixer lining, thereby reducing the air gap without changing refractory lining thickness (Bolotin et al, 2017;Bolotin et al, 2018;Bolotin et al, 2019).…”

Purpose The purpose of this paper is to search optimal shape of soft magnetic composite-based inserts used to compensate the working gap between the liquid metal and the induction stirrer in metallurgical installations. Design/methodology/approach The study was based on numerical simulation of electromagnetic processes in frequency domain. To optimize inserts shape, the Nelder–Mead method was used. The maximum of integral electrodynamic force along x-axis was chosen as the objective function. All simulations were performed in finite element software package Comsol Multiphysics. Findings Optimal inserts shape was determined, at which the value of integral electrodynamic force along x-axis increased by 20% from 692 to 792 N. Originality/value Magnetic concentrators based on soft magnetic composite materials have long been used in high-frequency systems; at the same time, their use in low-frequency systems has not been previously considered in detail. The study of the shape effect of concentrators on the effectiveness of electromagnetic field in a liquid metal in a three-dimensional formulation was carried out for the first time.

“…The technology of multicomponent alloys preparation implements an important operation, which is the homogenization of chemical composition and temperature of the melt (liquid metal) in the full volume of the alloying furnace bath [1]. The use of MHD stirrers enables to automate the homogenization process, to reduce the preparation time and decrease the power consumed for the production of high-quality alloys [2][3][4][5].…”

This article describes the electromagnetic field analytical model of magnetohydrodynamic (MHD) stirrer with nonsinusoidal current, built with the account of the longitudinal edge effect. The solution is obtained in the form of a Fourier series in a comprehensive way. Differential and integral properties of the system have been defined. There have been received differential and integral characteristics, which are the basis for building the power supply source and control systems for the liquid metal stirring process.
