GEORGE EREDERIOK ANSELL,
or BERNARD STREET, RUSSELL SQUARE, ENGLAND.
Letters Patent No. 104,686, dated June 28, 1870.
IMPROVEMENT IN THE MANUFACTURE or IRON AND STEEL- The Schedule referred to in these Letters Patent and making part of the same.
To all whom it ma y concera: v 4
Be it known that I, GEORGE EREDERIGK AssELL,
of Bernard street, Russell Square, in thecounty of Middlesex, England, have inveutednew and useful Im- PIOYBIIIEDCS in the manufacture of Iron and Steel; and
I do hereby-declare that-the followingis a full, clear, and exact description thereof; which willenable others skilled in theart to make and use the same.-
This invention relates some conversion of iron into steel, or into wrought iron, for armor-plates, railways,
. and for other 'purposes,:bythe use of bisulphate of .potash, or the bisnlphate of soda, or a mixture of the two, the same being applied in sucha manner as to act throughout the mass of melted metal.
For this purpose t-he bisulphate may be placed at thebottom of a com'ertingI-chamber or receiver, consisting of a vessel lined with. fire-clay, and furnished with a bedfofsand or loam. j L
Iutothis chamber the melted metal is then to be poured,0r the converting-chamber may have ridges or lodges ranged round its interior, upon which the bis'ulphate may be disposed, to facilitate its mingling withthe molten metal. v V
Thebisulphate may also be first heated ormelted before being used, and it may be pouredinto the chamber or receiver,in a heated state, sin1ultaneously w th the meltezl metal, so thatitheir admixture may commence in the'act of being poured into the receiver. a
By'means of the oxygen contained in and liberated y from the sulphuric acid of the bisulphate any phosphorus, sulphur, carbon, vanadium, and silicon contained in the melted metal willbe eliminated by the chemical action which will take placeand will take the form of slag, which, when 'set, may be readily separated from the metal.
The receivenmay have a tap-hole at the bottom, to .run ofiE'th'e purified or converted metal,
The quantity of bisulphate to be employed must depend on the amount and proportion of phosphorus, sulphur, carbon, silicon, and other impurities contained in and intended to be eliminated from the iron or steel,
' which must be ascertained by analysis, and the quantity of bisulphate must be so proportioned as that there fied or wrought iron, a sufiicient quantity of spiegelbe added, to recarbomze eisen, or its equivalent, may the iron.
\Vhere there is a smelting-furnace, the melted metal may be run directly from it into the converter, or a succession of converters, direct, so that the conversion may be without any intermediate heating or remelting, or the metal may be run through tubes, channels,
or colander-s containing the 'bisulphate, and whichwill serve as converters, and may thence be discharged into molds or other receiving-vessels, where the metal will; set in the form of ingots, pigs, solid cylinders, spheres,
or otherwise.
The slag that may adhere to these castings maybe readily separated therefrom by a hammer.
Where it is desired to eliminate phosphorus, carbon, silicon, sulphur, vanadium, or other impurities from manufactured iron or steel, the metal must be melted and treated with bisulphate, as already described.
Having now described the nature of my invention, I wish it to be understood that I claim the useot' bisulphate ot' potash or soda, or ot'a combination of these substances, for the oxida tion and removal of the impurities ofand from iron and stecl','as herein described.
In witness whereof, I, the said GEORGE FREDERICK AXsELL, have hereunto set my hand and seal the 10th day of February, 1870.
