ALEXANDRE JULLIEN, OF PARIS, FRANCE.
IMPROVEMENT IN CONVERTING OLD IRON INTO STEEL.
Specification forming part of Letters Patent N 0. l63,00, dated May 11, 1875; application filed July 18, 1874.
To all whom it may concern:
Be it known that I, ALEXANDRE JULLIEN, of Paris, France, manager of the Foundries and Forges Company, of Terre Noire, La Voulte, and Besseges, in the French Republic, have invented a new and Improved Process for Converting Old Iron into Steel, of which the following is a specification This invention relates to certain improvements in the manufacture of steel from castiron and wrought-iron, combined with a percentage of ferro-manganese, the object being to utilize the old and comparatively worthless wrought-iron in the market for the manu facture of steel.
The invention consists of a compound formed by melting in a SiemensMa-rtin or other suitable furnace, one thousand parts of cast-iron, selecting that which contains less than one-thousandth part of phosphorus, and adding from time to time suitable quantities of wroughtiron in the shape of old nails, axles, and the like, the whole quantity varying from two thousand five hundred to three thousand of carbon present in. the cast-iron. After the mass has all been reduced to a molten state, sixty-five parts, or thereabout, of ferro-manganese, containing about sixty per cent. of manganese, are added in fragments from time I to time to the mass, and melted therewith. The materials must be quickly mixed during this process until the whole are thoroughly melted and combined, after which the compound may be run off into molds and formed into ingots.
In carrying out the invention, the following proportions have been found to answer well, although they may be considerably varied, according to the percentage of carbon in the cast-iron: White cast-iron, one thousand kilograms; old wrought-iron, such as old English rails, for instance, two thousand six Witnesses:
