IMPROVEMENT IN CONVERTING CAST IRON INTO STEEL.
The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern Be it known that we, WILLIAM HARRIS and ADAM WOOLEVER', both of the city of Allentown, in thecounty of Lehigh and State of Pennsylvania, have invented a new and useful Improvement in the Process for Converting Cast-Iron into Steel; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the altto make. and use the same.
Our process consists in commingling with melted cast-iron certain chemical substances, which, being decomposed by the intense heat of the iron, produce the requisite chemical change and quality in the latter,- which is known as steel.
The chemical substances which are thus cummingied, and'the usual proportions of the same, are as folows:
Common salt, one quart; salt-peter,one pound; glass, one pound; antimony, one pound; blackoxide of manganese, four pounds; fullels earth, two pounds; sulphurio acid, two pounds; litharge, two pounds; pulverized charcoal, three quarts.
The abovequantities are sudicient for a charge of about four hundred and twenty-five-pounds of castiron, more or less... V
The iron is melted until quite thin in a puddling or other suitable furnace, and the above-mentioned substances are intimately mingled together, (on otherwise,) and then stirred into the iron by the usual puddling manipulations until the same is withdrawn from the furnace.
By conducting steam into the stack of the puddii'ngfurnace at the proper time, it creates a strong draught, and rapidly removes the impurities and gases which are expelled from the metal by the chemicals used.
1V6 also form a bottom in the puddling-furnace from the cinder and slag of wrought-iron scrap. 'lhisbottom is less-impregnated with impurities, and makes better and clearer steel.
metal until it shows a fine grain.
The pig-iron used should be broken into equal sizes, so that the pieces will melt at the same time, and when the iron is thoroughly melted the damper is then to be closed and the blast taken ofi'. Thenput in the chemicals.- Then work the heated mass thoroughly for a few minutes. the blast, and apply the steam to the furnace-stack to create a strong or rapid flame and heat, and thereby rapidly expel the gases and other impurities from the Then the steam and blast are taken'olf and the damper closed. Then the pulverized charcoal is thoroughly stirred into the mass by the usual puddling manipulations. Then the damper is raised and the blast put on, and the furnace to be kept full of flame up to the stopper-hole until the melted mass begins to drop. 7 Then the damperis closed within one link, and the blast reduced, so as only to keep the furnace full. of flame and exclude the air. p, Then, when it drops, keep it down in its cinder or slag by the tool, and close the mass together so as to prevent'a lap, and thereby keep in all the carbon Witnesses:
