TH17964EX - "The arc arc furnace uses direct current and how to use it" - Google Patents

Abstract

There is a description of the electric arc furnace that uses direct current. In a form with an electrode The negative electrode is in the middle of the melting container. And the positive electrode was placed with the container in the area of the bottom of the container that was conductive. From the wall of the container into the molten matter Power supply And the discharge occurs on one side through the wires to the power supply of the rectifier. Stream established in By the side of the stove, the bottom container is connected into several crescent circles with short wires and in the area of each circle There are connecting plates on the stove wall. When it is closer, beneath the arc of electric sparks Power supply is directed in the horizontal plane. Towards the furnace wall Current intensity for a circle of The bottom container next to the rectifier power supply. Is lower than the intensity of the power supply. To the rest of the circle The connection plate slots for the crescent area may not be equal
