PROCESS OFf RECARBONIZING STEEL.
SPECIFICATION forming part of Letters Patent No. 430,199, dated J' une 17, 1890.
Application filed March 3, 1890. SerialNo. 342,373. (No model.) Patented in Luxemburg January 23, 1890, No. 1,244.
To all whom it may concern:
Be it known that we, AUGUST SPANNAGEL and FRITZ SPRTNGORUM, both subjects of the German Emperor, residingat Haar, near Ruhrort, Rhenish Prussia, Germany, have invented a certain new and useful Improved Process of Recarbonizing Steel, (for which Letters Patent have been granted to one John Henry Darby, in Luxemburg, dated January 23, 1890, No. 1,2445) and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same. A
In the specification of a United States patent granted to one John Henry Darby, under date of July 9, 1889, No. 406,480, there is described a process of carbonizing crude iron or steel by ltering 'or causing the molten metal to pass from the ladle through a mass of carbonaceous material contained in a vessel, Where it takes up the required amount of carbon, and from thence passes into a supplementary casting-ladle. NVhile we have found this to work well in practice, in many cases where the works do not possess the means for casting the steel from one ladle to another it is difficult to apply, While in some cases there is not room enough between the mouth of the converter when in its lowest position and the ladle to allow of the interposition of the carbon-vessel and supplementary ladle. Ve therefore propose as an alternative method to introduce the carbon into the steel by causing a regulated stream of carbon to meet and intermix with a regulated stream of the crude metal, thereby insuring an energetic and complete combination.
A convenient arrangement of apparatus for carrying the process into effect is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a part of a ladle-crane with our improvements applied thereto, and Fig. 2 is an end elevation of same.
The carbonizing material, which may be coke or other suitable form of carbon, is thoroughly ground, and after any moisture A, which is carried by the arm of the crane.
This hopper communicates with a spiral or n worm B, working in a tube which maybe operated by bevel-gearing a c. from a handle b. The movement of this spiral will cause a regulated quantity of the carbon to be discharged into and down an inclined chute or trough C into a small vessel D, lined with refractory material, which is placed between the ladle E and the ingot-mold F. lThe carbon discharged into the vesselD meets therein the stream of metal from the ladle E, and after becoming thoroughly incorporated with it the stream passes through an opening in the bottom into the ingot-mold F. The steel produced by this method will stand quiet in the molds, so that the addition of ferro-silicon is unnecessary, while the amount of carbon in same may be arrived at with great certainty. If desired, a certain quantity of spiegel or ferro manganese may be irst added to the metal. In place of the spiral or Worm a wheel having compartments may be employed, or, in fact, any other device by which a regulated quantity of the material may be delivered. Vhere absolute uniformity of carbonization is not necessary, the small vessel D may be omitted and the combined stream of metal and carbon may iiow directly into the mold.
Vhat we claim, and desireto secure by Letters Patent, is-
The herein-described process of converting crude metal into ingot iron or steel, which consists in causing a regulated stream of carbonaceous material to mix with the stream of molten metal from the ladle before its entrance into the ingot-mold, substantially as described. y
In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
