ELECTRIC FURNACE MEMBER AND PROCESS OF MAKING IT.
Specification of Letters Patent.
Patented Jan. 7 1913.
Application filed October 12,1911. Serial 110,654,414.
To all whom it may concern:
Be it known that I, FREDERICK M. BECKET, a subject of the King of Great Britain, residing at Niagara Falls, in the county of Niagara and State of New York, have invented certain new and useful Im rovements in Electric Furnace Members an Processes of Making Them, of which the following is a specification.
This invention relates to a compound article for use as a lining, wall, electrode or resistor of an electric furnace, comprising a body of carbon and an adherent facing of tungsten or a tungsten alloy, preferably a ferro-alloy high in tungsten, e. 9., one containing 80 per cent. or upward. For the production of such article, a block or plate of carbon, such as graphite, may be caused to superficially react on atungsten com-' pound reducible by carbon. For example, a tungsten ore containing iron is heated to the point of fusion, a flux being added if desired, and a portion or all of the block to be coated is then submerged in the molten bath, whereupon the surficial portion of the block effects reduction of the ore and is replaced by an adherent coating of ferrotungsten.
A bar or block of graphite, for example one of the electrodes of a furnace, may be lowered into a molten bath containing a tungsten compound and a reducing agent, whereupon a layer of reduced tungsten or ferrotungsten is deposited on it, the initial coating being reinforced by metal reduced from the bath, and attaining a final thickness dependent on the temperature of the bar and bath. By cooling the bar or electrode, as by using a water-cooled terminal head, and by using a suitable current density, a thick layer of tungsten or ferrotungsten may be provided. Or the tungsten or its alloy may be electrodeposited upon a carbon electrode by constituting it the oathode of a molten electrolyte containing a tungsten compound.
I claim:
1. An electric furnace member, comprising a body of carbon and an adherent coating consisting essentially of tungsten.
2. An electric furnace member, comprising a body of carbon and an adherent coating of ferrotungsten.
3. The process of making a composite furnace member comprising a body of carbon and a coating consisting essentially of tungsten, which consists in causing the body to superficially react on a tungsten compound reducible by carbon.
4. The process of making a composite furnace member comprising a body of carbon and an adherent coating of ferrotungsten,
which consists in bringing the body in contact with a fused mixture of compounds of tungsten and iron reducible by carbon.
5. The process of coating a body with a layer of tungsten or a tungsten alloy, which consists in depositing the metal or alloy on said body from a molten bath, and simultaneously cooling the body.
6. The process of coating a body with a layer of a metal or alloy, which consists in depositing the metal or alloy on said body from a molten bath, and simultaneously cooling the body.
In testimony whereof, I aflix my signature in presence of two witnesses.
FREDERICK M. BEOKET.
