THEODORE R. TIMBY, OF WASHINGTON, DISTRICT OF COLUMBIA.
PROCESS OF PURIFYING IRON AND STEEL.l
SPECIFICATION forming part of Letters Patent No. 462,602, dated November 3, 1891.
Application tiled October 27, 1890' Serial No. 369,510. (No model.)
`T0 @ZZ whom, t may concern.'
Be it known that I, THEODORE R. TIMBY, a citizen of the United States, residing in the city of IIIashington, District of Columbia,
have invented a new and useful Process ofA Purifying Iron and Steel, of which the following is a specification.
My invention relates to a process of ridding molten iron'from sulphur, silicon, and other impurities, as Well as from excess of carbon, to which end I employ a jet of hot air mixed With decomposed or super-heated steam and with the addition of vaporized animaloil, preferably {ish-oil or whale-oil, as hereinafter described.
In carrying out my invention I prefer to take from tive to ten or even fifteen per cent. of fish or Whale oil, together with Water, in a sui-table boiler, highly heating the oil and vaporizing the Water, and introduce this combined heated oil and Water-vaporin jets into the cupoia through suitable pipes or nozzles Within the tuyeres through which the airblast is introduced. The superheated steam and oil mixed with the hot-air blast effect the rapid combustion and discharge of carbon, sulphur, silicon, and otherimpurities, the oxygelnwith the air-blast, decarbonizing the metal and the hydrogen of the decomposed steam with the oil-vapor having a greater aflinity for the sulphur, dre., combining with and carrying oif the same, resulting in the refining of the iron and decarburizing to any extent desired, governed by the length of time and ascertained by observation ot' the combustion of the resultant gasesas in the Bessemer and other processes of converting iron.
My process is employed in the production of steel of various grades and of refined iron ready for blooming.
It. will be understood that my improved process is applicable to the manufacture and conversion of iron and steel in cupolas, blastfurnaces, and converters of various kinds.
The accompanying drawing is a sectional elevation of a cupola with suitable boiler or vaporizer and blast attachments by which my invention may be carried into effect.
R represents the vaporizing boiler or retort, O the cupola, and T T the compound tuyeres, each provided with an internal steam-nozzle and communicating by pipes S with the vaporizing boiler or retort R, so as to discharge the united steam and oil into the cupola O or otherblast-furnace or converter in connection with the air-blast, which is forced by a suitable blower B through pipes Band delivered through the tuyeres T T. The air-blast may be heated by any suitable means.
AHaving thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:
l. The process of converting or decarburizing and purifying iron, which consists in4 introducing mingled jets of animal-oil and decomposed or superh'eated steam into the molten metal, substantially as set forth.
2. rIhe process of convertingior decarburizing and purifying iron, which consists in introducing mingled jets of hot air, decomposed or superheated steam,and animal-oil into the molten metal, substantially as set forth.
TI-IEODORE R. TIMBY.
