SPECIFCATION forming part of Letters latent N0.`7l0,882, dated October 7, 1902.
Application filed December 6,1901. Serial No. 84,920. (No modem To (rj/IZ 11171/0711/ if ntf/,y concern:
Beit known that I, SHELDON NoRroN,a citi- Zen of the United States of America, residing at Oatasauqua, in the county of Lehigh, in the State of Pennsylvania, have invented new and useful Improvements in the Art of Molding Slag, of which the following is a specification.
My invention has relation to improvements in the art of molding articles directly from molten furnace-slag; and the object is to produce directly from molten furnace-slag articles of forms, such as bricks, tiles, and ornamental faces and blocks.
l accomplish the object by taking the molten slag from the furnace Where it emanates, then conveying it to a second furnace, Where it is deposited in a Crucible or other suitable receptacle Within the combustion-chamber of the second furnace, then introducing and incorporating earthy material in the slag, and then restoring the mixture to a fused condition and so maintainingit. The molten mixture is then poured from the crucible into molds traveling in the combustion-chamber of the furnace and passing through an elon gated annealing and solidifying .flue of gradually-decreasing temperature and discharged at a point for removal.
l have illustrated in the accompanying drawing a form of furnace and apparatus by which the invention may be practiced. The furnace for maintaining the slag in molten condition and for annealing and in which the forms become solidified in their passage through the extended portion or lengthened flue of the combustion-chamber is slioivnin longitudinal vertical section and the appliances and mechanisms in side eleva-tion, and, reference being had thereto, A designatesa furnace, B the fuel-chamber, and C the combustion-chamber extended into a iine of such length that the molded articles may pass through a channel or area of gradually-decreasing temperature from point of deposition to the point of discharge and in the passage become gradually annealed and sufficiently solidied to be discharged at the outer end of the carrier. The stack rises from the outer end of the lengthened flue of the combustion-chamber opening from an enlarged poured.
tub-ring 9 are journaled.
room E, formed under the stock by the upwardly-inclined furnace-roof and the extension of the rear Wall of the furnace, as shown. In the roof of the furnace, at the rear and adjacent to the bridge l of the furnace, is an opening 2, through which the molten slag is This opening may be closed by any suitable closure, When desired.
F designates the slag-delivering tub. This is mounted on trucks 3 4, mounted on a track The trucks have substantial standards 6 rising therefrom, formed with bearings through them, in which the gudgeons 7 S of a In the tub-ring is arranged the slag-tub F, as shown. Directly under the opening 2 in the combustion-chamber of the furnace A is the crucible G, mounted to turn and tip on bearings lO, and may be turned thereon by means exterior of the furnace and connected thereto. Longitudinally arranged in the combustion-chamber of the furnace below the general line of draft is mounted a mold-carrier H. This comprises a drum ll, suitably mounted at a point below and adjacent to the crucible G, and at the rear end of the flue, on a higher plane than the drum ll, is arranged another drum l2. On these drums is arranged a traveling endless carrier le, extending on a line substantially parallel with the roof of the flue and consisting of a series of links 15, arranged in endless succession on the drums and formed with molds designed to be filled with the material deposited from the crucible. At the end of the carrier is arranged an inclined plate or Way 1G, on which the solidified forms are discharged from the carrier onto a car or truck 17 to be conveyed to a desired place.
While the described process may, as described, produce a brick or other form of slag article, the process embraces the introduction and incorporation in the fused slag contained in the crucible in the furnace of earthy material` as clay or its equivalent, and then again subjecting the mixture to fusion preliminary to pouring it off into the molds.
The apparatus being substantially of the construction and arrangement described, the steps in the process are carried out as follows: The molten slag is deposited in a ladle or tub at the smelting-furnace (or is run directly IOO therefrom) and poured into the crucible Gin the combustion-chamber of the fuel-chamber B. After the required quantity of slag has been supplied to the crucible the earthy material is added for the purpose of imparting toughness to the mixture. The mixture thus made is then again subjected to heat while in the Crucible to restore the fusion, which being accomplished it is poured from the crucible into the molds, which are carried on the endless carrier through the extended ue and in their course subjected to a gradually-decreasing temperature, so that by the time they reach the limit of the carrier they become annealed and sufiiciently solidified to be discharged.
The introduction and incorporation of the earthy matter are for the purpose of imparting toughness and to cause the slag to assume a vitreous quality. Coloring material may be introduced in the molten slag While in the process of its transportation from the smelting-furnace either in the tu'b or runner, or it may be incorporated in the material while'in the crucible, as may be deemed the better.
Having described my invention, what I claim is The improvement in the art of molding` slag consisting in pouring molten slag into a Crucible heated to a fusing temperature to sustain the fusion, then mixing earthy material with the fused slag, then restoring the mixture to fusion, then pouring the fused mixture-into traveling molds, then continuing the movement ofthe filled molds through an elongated flue of gradually-decreasing temperature to anneal and solidify them, and then discharging themolded articles from the carrier.
In testimony whereof I affix my signature in presence of two witnesses.
