Abstract

The electrode arrangement uses vertically oriented electrodes with side wall contacts for an electrothermic smelting furnace for aluminum production. The side wall contacts are radially moveable into the furnace to compensate for wear on the contacts. The side wall contacts can be hollow to allow a slag forming charge to be fed to the furnace.

Lance for fuel and oxygen injection into smelting or refining furnace

Patent Schlichting, Mark R [Chesterton, IN]

A furnace 10 for smelting iron ore and/or refining molten iron 20 is equipped with an overhead pneumatic lance 40, through which a center stream of particulate coal 53 is ejected at high velocity into a slag layer 30. An annular stream of nitrogen or argon 51 enshrouds the coal stream. Oxygen 52 is simultaneously ejected in an annular stream encircling the inert gas stream 51. The interposition of the inert gas stream between the coal and oxygen streams prevents the volatile matter in the coal from combusting before it reaches the slag layer. Heat of combustion is thus moremore » « less

Ferrosilicon smelting in a direct current furnace

Patent Dosaj, Vishu D [Midland, MI]; May, James B [Midland, MI]

The present invention is a process for smelting ferrosilicon alloy. The process comprises adding a carbon source and tailings comprising oxides of silicon and iron to a substantially closed furnace. Heat is supplied to the furnace by striking a direct current arc between a cathode electrode and an anode functional hearth. In a preferred embodiment of the present invention, the cathode electrode is hollow and feed to the substantially closed furnace is through the hollow electrode.

Control of carbon balance in a silicon smelting furnace

Patent Dosaj, Vishu D [Midland, MI]; Haines, Cathryn M [Midland, MI]; May, James B [Midland, MI]; ...

The present invention is a process for the carbothermic reduction of silicon dioxide to form elemental silicon. Carbon balance of the process is assessed by measuring the amount of carbon monoxide evolved in offgas exiting the furnace. A ratio of the amount of carbon monoxide evolved and the amount of silicon dioxide added to the furnace is determined. Based on this ratio, the carbon balance of the furnace can be determined and carbon feed can be adjusted to maintain the furnace in carbon balance.

RF driven sulfur lamp having driving electrodes arranged to cool the lamp

Patent Gabor, George [820 Skywood Rd., Lafayette, CA 94549]; Orr, Thomas Robert [2285 Vestal, Castro Valley, CA 94546]; Greene, Charles Maurice [6450 Regent St., Oakland, CA 94618]; ...

A high intensity discharge lamp without mercury is disclosed radiating a selected spectrum of which can be almost entirely in the visible range from an envelope that contains a sulfur containing substance. The lamp utilizes a signal source that generates an excitation signal that is externally coupled to the exterior surface of the envelope to excite the enclosed sulfur containing substance. Various embodiments of the lamp use electrodes adjacent the envelope to couple the excitation signal thereto with the face of the electrodes shaped to complement the shape of the exterior surface of the envelope. Two shapes discussed are sphericalmore » « less

Electrode immersion depth determination and control in electroslag remelting furnace

Patent Melgaard, David K [Albuquerque, NM]; Beaman, Joseph J [Austin, TX]; Shelmidine, Gregory J [Tijeras, NM]

An apparatus and method for controlling an electroslag remelting furnace comprising adjusting electrode drive speed by an amount proportional to a difference between a metric of electrode immersion and a set point, monitoring impedance or voltage, and calculating the metric of electrode immersion depth based upon a predetermined characterization of electrode immersion depth as a function of impedance or voltage.
