Universal MHD device for automation of casting control of aluminum

Abstract

The article proposes an MHD device designed to automate the management of casting aluminum melt from a stationary mixer. The product is made on a modular basis, similar to an induction detachable unit, has three magnetic cores with windings. The design of the MHD device, the location of the magnetic cores, and the features of connecting the windings to the network turn it into a universal unit. The location of the casting trough inside the closed cores allows the device to be used as an MHD pump for aluminum melt. Methods of connecting the windings make it possible to realize the function of dosing the melt using automated process control systems. Pumping the melt through the chute when placing the module between two sockets ensures stirring of the melt in the mixer. The use of a group of single-phase transformers in three-phase switching ensures the movement of aluminum in the channel by creating traction forces in the melt. The presence of windings, allowing for opposition, puts the electromagnetic module into transformer-inductor mode, improving energy efficiency in traction modes, providing melt heating beyond the furnace and maintaining aluminum temperature.
