Abstract
The experience of designing a secondary current supply for an ore recovery furnace with a round tub designed to replace a furnace with a rectangular tub is considered. At the same time, the power supply has far from exhausted its working life, and its replacement was not expected. Traditional design solutions for a short network of a round ore recovery furnace, providing a satisfactory level of its electrical parameters, involve the use of a secondary current supply circuit “triangle on electrodes.” The dismantled furnace had a “star on transformer” secondary current supply circuit. New design solutions have been developed based on the general physical laws of the formation of the electromagnetic field of a system of conductors with currents. Their use provided a sufficiently high level of input active power, which also made it possible to reduce the asymmetry of the inductive resistance of the secondary current supply from 58 to 10% compared with the old furnace. The study used the method of numerical modeling in specialized ANSYS software with the integration of a geometric model from a computer-aided design system.
Abstract The experience of designing a secondary current supply for a ore recovery furnace with a round tub designed to replace a furnace with a rectangular tub is considered.与此同时，该电源的工作寿命还远远没有结束，而且预计不会更换。传统的圆形矿石回收炉短路网络设计方案是使用 "三角形电极 "二次电流供应电路，从而使其电气参数达到令人满意的水平。拆除的熔炉采用了 "变压器星形 "二次电流供电电路。新的设计方案是根据电流导体系统电磁场形成的一般物理规律制定的。使用这些方案可以提供足够高的输入有功功率，还可以将二次电流供应的感应电阻不对称程度从旧炉的 58% 降低到 10%。该研究采用了 ANSYS 专业软件中的数值建模方法，并结合了计算机辅助设计系统中的几何模型。
