Abstract
An electro furnace for metallurgic operations has its top connected to a vertically extending cylinder, into which a charge pipe leads at an oblique angle. A ceramic plug glides in the cylinder in piston like fashion for selective opening and closing the opening from said charge pipe. Any burden and ore mixture will therefore fall freely from the charge pipe whenever the plug is shifted up to open the gate.
