Original application filed 1925, Serial No. 20,317.
The present application is a division of my: co-pending application, Serial No. 759,- 086 filed December 31, 1924:, andthe invention embodied herein relates to molds for forming ingots. The object of the present invention is to produce a mold adapted to carry out the method of forming ingots embodied in said application, Serial No. 759,036 and to produce an ingot in which waste or diminution of the workable volume of the ingot occasioned by the formation of a fissure, commonly called a pipe, at the center interiorly of the ingot is eliminated or reduced to a minimum. I accomplish this object by means of the apparatus hereinafter more specifically described, reference being had to the accompanying drawings forming part hereof, in which:
Fig. 1 is a vertical central section of one form of mold.
Fig. 2 is a vertical section of the same on line AA of Fig. l. v Fig. 3 is a top plan view of the mold. Fig. 4 is a perspective view of a partition plate used in the mold shown in Fig. 1.
Fig. 5 is a vertical section of a modified form of mold. Fig. 6 is a plan view of the same. Fig. 7 is a vertical central section of an-' other form of mold.
Fig. 8 is a top plan view of the same, the cap. being removed.
Fig. 9 is a vertical section of a mold through line B-B of Fig. 11.
Fig. 10 is a transverse vertical section on line 0-0 of Fig. 11.
Fig. 11 is a top plan view. Fig. 12 is altransverse horizontal section on line D-D of Fig. 9. y
Referringto said drawings and'particit larly to Figs. 1 to 4 and 9 to 12 inclusive: 1 is a mold adapted to produce a plurality of ingots, the said mold having at or near the center thereof and extending from the top to the bottom thereof and suitably se cured therein a partition plate or plates 2. In the present embodiment of my invention the walls of the mold have a groove or grooves a extending from-the top to the bottom thereof in which said partition is secured, the said partition being formed of any suitable substance, or any substance or material which possesses the capacity of absorbing relatively less heat from the molten steel than the remaining portions of the December 31, 1924, Serial No. 759,036. Divided and this application filed April 6,
Renewed October 17, 1927.
mold. The said partition when formed of metal as for instance, wrought iron or other metal, is much thinner than the remaining portions of the mold in order to reduce its heat absorbing capacity with relation to the remaining portions of the mold.
The said partition plate may be formed of a single plate 2 of any suitable substance, such as asbestos or fire clay, as shown in Figs. 1 and 3, or of asbestos plates 3-3 which are suitably secured to opposite sides of a metal plate 4: and asbestos fibre X arranged between said asbestos plates 3-3 and above said plate 4,'as shown in Figs. 10 to 12 inclusive. The said mold shown in said figures is adapted to be supported in the usual manner upon a base plate 5 and is divided into two compartments A and B by the partition member, as shown in Fi s. 1 to inclusive, and Figs. 9 and 12 inc usive.
The lower edge of said partition member near the center thereof may be provided with a recess 6 adapted to establish communication between the compartments A and B, asshown in Figs. 1 and 2; altho this is not essential as the two com artments may be filled independently. T e upper end of the said partition member, as shown in Figs. 1 to 3 inclusive, may also be provided with downwardly projecting slits C which are adapted to establish communication between the compartments A and B- at or near the top of the mold which, with the recesses in the lower edge of said partition member, forms thin connecting mem bers between the two ingot units on each side of the partition member or plate for the purpose of holding said ingot intact if and when the mold is removed before the solidification of the ingot is complete.
The said connecting members are attenuated so as to be readily broken in order to separate the individual units constitutingthe ingot into two separate ingots. The up per endof the partition member or plate, as shown in Figs. 1 and2 supports or carries a block 6 formed of asbestos or other substance adapted to aid in retaining heat in the molten metal and retard the cooling thereof atthis point. The said block as shown by dotted lines is.carried by the partition member or plate and extends below the top of the upper end of the mold and, bein lighter than the molten steel, will rise wit the metal as the same is poured into the mold and ultimately covers a portion of the top of the mold at or near the center thereof and serves to retard the radiation of heat therefrom.
The mold as shown in all the figures may be formed in sections when deirable, on opposite sides of which is formed laterally projecting lugs 7 through which bolt holes are formed for the pur ose of enabling the said sections to be bolte tightly together by means of the bolts d and to enable the same to be loosened readily to permit the easy removal of the ingots. It is obvious that the mold may be formed in one piece orthat the sections, when the same is formed in sections, may be secured together in any suitable manner other than the one described.
In Figs. 5 and 6 is shown a mold for the roduction of a single ingot, the said mold liaving three of its sides constructed of the usual material havin relatively the'same heat conducting and heat absorbing caacity and the remaining side of said mold ormed of a substance or material having relatively low heat conducting capacity and low absorbing ea acity as compared with the remaining wa ls of the mold. Specifically the form of mold shown in Figs. 5 and 6 consists of a mold having three of its walls constructed of the usual material and of the usual thickness, and the remaining wall being formed of sections G and H and a plate 8. The said plate is arranged on the inner side of said sections and inter osed between the ingot and said sections and The said section G and the plate 8 are formed of a substance or material of low heat absorbing capacity as com ared with the remaining walls of the mo (1 and section H.
In Figs. 7, 8, I show another modified form of mold which comprises a mold having three of its walls of the usual thickness and formed .of the usual-material, the remaining wall consistin of the sections 9, 10 and a plate 11 forme of asbestos or other suitable material havin low capacity for absorbing heat, arrang at the inner side of said sections and interposed between the said sections and the in ot and between the upper end thereof and t e upper end of section 9 forming an air chamber 12, the said air chamber being adapted to be closed by the cap late 13. 7
It is o vious that a number of ways may be suggested for securing the partition in the mold; the one herein shown being in the opinion of the inventor one of the simplest ways of securing said partition therein.
In Figs. 9 to 12 inclusive, I show a partition member formed of two plates 3-3 of asbestos supported in the mold in a manner similar to that shown in Figs. 1 and 3. The said plates being spaced apart and between the lower ends thereof a metallic plate 4 being interposed. Above the metallic plate and between said asbestos plates the space is filled with asbestos fibre X, or other suitable substance of low heat absorbing capacity. A plate or cap 16 is adapted to closethe space between said asbestos plates, as shown in Figs. 9 and 10.
Having described.my invention, what I claim and desire to secure by Letters Patent is:
1. A mold for forming a plurality of ingots having their final shrinkage fracture along the external upper edge, said mold having a permanent-partition disposed centrally thereof, dividing the mold into two in dependent compartments, the said partition havin substantially less capacity to absorb heat t 1an the remaining portion of the mold.
2., A mold for formlng an ingot having its final shrinkage fracture along the external upper edge, said mold having three of its sides constructed of material having relatively the same heat conducting and absorbing capacity, and the remaining side formed of material having a relatively low heat conducting capacity.
3. A metal mold for'forming a plurality of ingots having their final shrinkage fracture along the external upper edge, said mold having a relatively thin refractory partition disposed centrally thereof, dividing same into two independent com artments, the partition having substantial y less capacity to the mold.
In testimony whereof, I have hereunto
