Patented Sept. to, 11912.
Application filed February 2 1'. 1911. Serial No. 610,526.
To all whom it may concern lie it known that l, ilnonon Human BEN- Jaizm, a citizen of the United States, rosiding in the city, county, and State oi New York, ha e invented certain new and useful .l mprtwouicnts in the Method of Treating .ldetal ingots, oi "which the following l s ucilication.
his is Well known, metal ingots during; the act of cooling, are subjected to the action of two forces, 2. e., (l) contraction. with the resultant formation of depre: ions or pipe in the body of the ingot'and (2) scg 'rcgr-ition, due to the ditl'erermc in specific gravity oi the materials t'omnin the ingot, with the result of unequal distritmtion of materials throughout. the ingot.
The object of my invention to over come the above stated objections.
To carry my invention into effect, I may use appornlus such as disclosed in the accompanying drawings. I wish it understood, however, that these drawii' on are in a sense diagranunatic and. merely intended to illustrate such apparatus as may he used, Without in any wise intending to confine my ii to the specific apparatus disclosed.
In the dra'o'in gs, Figures 1 and 2 are respectively horizontal and vertical sections o mold provided with heating means. F 3 is a horizontal plan yicw of a mold pr d with cooling means. Flg'. 4 is o vertical section of an apparatus in which ingot may be subjected to lateral pressure along a. portion of its length and r0- and Fig. is a partial plan View and u aontul section of Fig. 4-.. lln all of the figures an ingot is illustrated in position.
lie :1 preliminary step in the production of the ingot, I pour the molten metal into a mold B, so constructed that at least; one side of the mold. shall have a higher tem- 1981111211113 than the other sides of the mold. lhis ditlerence in temperature may be obtained by heating one side of the mold, or
one half of the mold, by heating apparatus C, C (Figs. 1 and 2), or by chilling three sides of the mold by a cooling apparatus 1), (Fig, 3), the particular design of heating or cooling a 'iparatus being immaterial, so long that used will fiCCQilI'lllSl'l the purpose desired. By costing the ingot in a mold having}; one side 0i": higher temperature than the other sides, one side of the ingot be prevented.
will retain a higher tempe'ature than. the ot-l'icr sides and as shrinkage takes place in the cooling of the ingot, the soft, metal upon, the heated side of the ingot will no commodate for such shrinkage and the usual cupping or the formation of pipe will After the ingot is cool enough to handle, it is lifted from the mold,
placed upon a carriage E, and inserted between pressure plates F-( El-, mounted upon shafts H, carried in. suitable hearings l. The plate G is made ad ustable to and from the ingot through the instrumentality of a.
hydraulic piston J. The plate F isdivided into two portions, one portion of which is fixed and the other portion K, made adjustable to and from the ingot A, by means of the hydraulic piston L. The purpose in using adjustable portion K of the plate F, is to provide means for compressing a portion of the soft side of the ingot, during the time shrinkage is taking place and the ingot cooling. Simultaneously with the exertion of pressurehy the portion K of the plate F,
the ingotis slowly rotated. The effect of the rotation is to overcome the tendency to segregation of the materials forming the ingot under the action of gravity, and this is aided by the lateral pressure along a. portion of its length exerted through the portion K of the plate F.
i am aware that it has heretofore been proposed to rotate theingot during the time that the ingot is cooling, and also to exert lateral pressure along the Whole side of the ingot, and such I do not claim as my invention.
What I claim as my invention is:
1. A step in the method of treating ingots which consists in casting the n'ietal into a. mold and maintaining the temperature of one side of the mold relatively higher than that of the other sides and bottom of the mold during the Whole time that the ingot is cooling.
2. A step in the method of treating ingots which consists in rotating the ingot after casting, and simultaneously subjecting the ingot. to lateral pressure along a portion of its length exerted against the Warm side of the ingot. i
3. The method of treatingingots which consists in first casting it in such manner that one side of the-ingot shall be Warmer than the other sides, and subsequently subllttl pressure along a. portion of its length eX- erted against the warm side of the ingot.
4. The method of treating ingots which eonsists in casting it into a mold provided with mean whereby one side of the mold shall be 'wazgner than the other sides, then withdrawing the ingot, rotating the ingot and subjecting the warmer side of the ingot to the action of lateral pressure along a portion of its length.
The method of treating ingots which consists in casting the metal into a mold, and then regulating the temperature of the sides and bottom of the mold to have that of one side relatively higher than that of the other sides and bottom, whereby all the shrinkage of the ingot will take place from without inward and at one side.
6. lhe method of treating ingots which consists in casting the metal into a mold, regulating the temperature of the sides and mold to a definite maintained temperature along three sides and the bottom of the mold, and to a dilierent maintained degree of temperature along one side.
In testimony whereof, I affix my s1gnature, in the presence of two witnesses. 4
