lil

A still further object of the present inveir tion is a casting plate or stool for horizontal.

ingot molds comprising a body portion and a edge adjacent one edge of said body portion and adapted to engage the ends of a suitable ingot mold.-

Other and further objects of the present invention will in part be obvious and will in part be pointed out hereinafter by real.- erence to the accompanying drawin wherein like parts are 'representedb .rr characters throughout the several gures Realizing that the present invention may be embodied in constructions other than those specifically shown, it is desired that thereof.

- Elli 50 form on the material going through. It

I the present disclosure-shall be considered as illustrative and. not in the limiting sense.

Figure 1 is a longitudinal sectional view through a mold, an infiot therein, and the stool on which said mol is adapted to rest;

Figure 2 is a plan view of the device shown in Figure 1;

necessary to of line 33 so that in the operation of the device on a casting floor it becomes necessary to dispose of a number of pieces of. the mold when strippin the ingot from the -mold. In view of t e fact that the parts are heavy and must be handled by cranes, such constructions involve a number of crane movements to strip a single ingot. Furthermore it is ispose of the various parts about the floor as these parts are removed. In steel plants which are established in their construction and organization, the

, handling of multi-parts delays the operation of the plant and increases the cost of the product. The disposal of extra mold parts often required abnormal travel of the crane and requires more space than is usually alloted for the casting floor and increases the element of danger and accident as well as the trouble of extra fitting and setting up. In factories producing steel ingots there are usually a series or chain of operations which begin with the pouring of the ingots and which may terminate in the finished product such as the rolling of structural iron, rails, or other commercial forms; or the product ma be an intermediate one such as steel hi] ets. The resultin roduction is controlled by that one o t e series of operations which requires the longest time to pertherefore follows that any manipulations or step which slows up the progress of thework eatly interfers with the final rate of re uction.

he present invention overcomes the difliculties of the known art by providing a horizontal ingot mold, method and apparatus wherein the space utilized on the casting floor for 'castin ingots in vertical molds mapl be adapte and used for casting ingots in orizontal molds without disturbing the final rate of production.

The present invention may be embd in constructions other than those spiflaeeapr cally shown and described herewith so therefore the present embodiment is more or less diagrammatic and for illustration may comprise an inverted ingot mold trough adapt ed to be set on suitable lates or stools so that the movable part of t e mold comprises one piece which, after being filled with. molten steel, and cooled, the ingot is automaticall strip ed fromthe mold by merely lifting t e mol which may be carried by a crane to a new stool or plate on which the mold may be set and made ready for another casting operation. This greatly facilitates simplicity of handlin and permits the equi ment to be released for re-use as quic (1y as the steel sets. Therefore this method requires no extra floor space for storage of sembling o a mold set-up.

Referring now to the drawings, which are more or less diagrammatic, the constructions parts during dissembling and as- I may comprise a floor plate or stool 1 which is ipreferably a heavy cast iron plate of a su cient width to support a plurality of ingot molds which may rest on the smooth top surface 2 of thestool. Preferably the stool or floor late is inclined and to this end may be rovi ed with supportinglegs 4 and 5 of di erent heights. To facilitate the setof the stool 1. One end of the mold body is provided with a suitable opening through which a fire clay or the like, runner 9 may extend. This runner preferably is provided with two inlet openings 10 and 11 through I which molten steel may enter into the matrix space when steel is poured into the fountain 12. Preferably the opening in the mold through which the runner extends is projected downwardly and forms a groove in the end of the matrix, which groove is lar r than the runner itself, thereby providing gas outlets 114 and 15 around the runner. These outlets extend through the top wall of the mold and communicate with passageways 16 provided beneath the fountain 12 so that theworkmenmay watch the flames of the escaping gas. When the flames stop the mold is filled. The openings 14 and 15 while sufliciently large to Ipermit free gas escape are not large enoug to cause undesirable fins to form on the end of the ingot. The end of the matrix portion of the mold opposito'to the runner is preferably curved or inclined as at 17. The curve or inclination of this end is slightly greater than a curved end "as a fulcrum or pivot.

0r arc ed surface. which would be formed by lifting the mold by the end-having the inclined surface and utilizin the runner 1 portion of the mold are also inclined as at 18 and 19 to provide clearance during the stripping operation. The ends of the mold carry suitable staples for permitting engagement of the crane hooks and preferably two staples are arranged at one end of the mold and one staple at the other end. Asa matter of convenience the two staples 20 may be arranged at the lower end of the mold and one staple 21 at the upper end thereof. These staples permit the crane to enga e the mold at three points, thereby forming a three point suspension by means of which the mold may be definitely, accurately, and positively handled.

In carr ing out the present invention the mold pre erably is set on the stool or floor plate as indicated in Figure 1 with one end of the mold against the foot rail 6. The molds may be set parallel side by side with the fountains thereof in a row at one end of the floor plate. As the ladle is carried from one mold to the other the molds are molds may be removed. Ihis is accomplished by inserting crane hooks in the staples 20 and lifting the lower end of the mold with the upper end thereof as a pivot in such manner that the mold acts as a pry to break off the runner column so that the ingot may be entirely freed when the mold is lifted away from the ingot. The double staple end may then be lowered slowly and the crane may then uniformly lift the mold entirely free of the ingot and re-set the mold in a new position on either the same or an other floor plate, at which time the new fire clay runner is inserted and the mold is ready for another operation. It will be noted that the inlet for the steel and the outlet for the gases is at the same end of the mold so that the gases continue to escape through the hot, fresh metal up to the in stant when the mold is completely filled with molten steel and until the gas outlet is chilled.
