Esselbakh V. Technology of iron-silicon-manganese ligatures receipt with the use of electromagnetic forces

The dissertation is developed and researched technology for producing iron-silicon-magnesium (ISM) ligatures from ingots of magnesium and liquid ferrosilicon using crossed magnetic and electric fields. Developed methods for calculating the structural parameters of the equipment used and the technological parameters of processing, the properties of ferrosilicon and magnesium, the effect on the current strength bath and magnetic fields, heat and mass exchange and hydrodynamic phenomena that occur when receiving ISM ligatures. For the industrial implementation of the technology proposed dual-zone ladle reactor. In the "active zone" serves ingots of magnesium and it is located between the poles of an electromagnet. As a "mixer zone" can be used in the shop used buckets for an arbitrary metal melt capacity. All the metal is pumped through the active zone and saturated with magnesium from ingots. Electromagnetic force holds the solid and molten magnesium melt in the depths of ferrosilicon, so there is no pyro-effect absorption of magnesium in the ligature increased by 20% compared with the most common way to enter the batch magnesium rod. In addition, improved working conditions, the homogeneity of alloy and decreases the volume of aspirating secretions. The economic effect by increasing the utilization of magnesium was 140.7 UAH per 1 ton of alloy produced in this way.
