CONVEYING ArraRA'rus 1 Application filed anew,
madejof some high melting pointalloy,such" as an alloy of nickel and chromium. So far 1, as we are aware, it has been the practice up to l thepresent time to cast the roll in one piece. Since the rolls arelarge, a good deal of V difiicultyis encountered in the casting proc ess. The difliculties of casting these rolls are great, not only because of the size of the rolls,
but also because the high melting point al-' loys have a tendency not to .knittogether properly when two streams of the alloy are run together.- It isdesirable to make these rollsas light as possible and stillhave 'suiin cient strengthto support, the conveyingdlscs and the material which is conveyed through the heat treating. furnace. Accordingly, it 15.
Q very diflicult tocast a largerollifrom a high meltingpoint alloy, particularly if it isde sired to produce a roll having a thin. wall. According to the present invention we decrease the difiiculties incident to the casting operation by splitting the rollgtransversely into a plurality of parts. This eliminates or decreases the difliculties of properly positioning and venting the cores and also results in V a roll having more uniform roll thickness. The molten metal has a shorter distance to run so that it is notcooled below the point at which molten streams of metal will properly knit together. The smaller sections of the roll made in accordance with our invention enables one to cast them in a vertical position. In the accompanying drawings, which illustrate two preferred embodiments of our invention, p Figurel is a plan viewof aroll split into two sections, parts being broken away and other parts being shown in section.
Figure 2 is a similar view illustrating a roll split into more than two parts; V
Figure 3 is a transverse'section on the line III-III "of Figure 1, and
1930. seriaiivaeeisea;
I. isa transverse section on the line IV1V of' Figure 2;
, Referring-more particularly to Figure 1,
the roll; indicated generally by the numeral 2Iis divided into twoparts 3 and4,; the split 5 being'niade at the center line'of the roll. The part/l is provided with'aiprojection 5 which fits into a recess 6 in the roll part 3 inorder to provide ,afgood seat and .properly'alinefthe i L parts. Each of the rollpart-s 3 and 4 is provided atadjacent endsiwith anoutw'ardly radiallyfeiztending-fiange which terminates in a horizontally 7 extending flange 8. The flanges are secured together by bolts .9, thereby uniting the two roll parts 3and 4.
Each of the roll parts 3 and 4 is provided with a plurality of material conveying discs I 10 spaced longitudinally of the roll. These discs maybe of any usual or desired construc tion and maybe secured to the roll in any desired manneri However, itis preferred to use dises of the type describedin our copend: ing application, Serial No. 429,042, filed F eb ruary 17, 1930;" The discs described in our 7 copending application can be made much lighterjthanthose ordinarily employed. Ac
cordingly, when such .discs are used, the roll itself; maybe made lighter by reducing the wall thickness. The decrease, in wall.tl1ick-.
ness would ordinarily result 'in casting difii culties, but".thesejdifiiculties may be overcome by dividing the roll into a plurality ofv parts, ,as described' in the present application.
The flanges 7 extend outwardly from the roll for a distance substantially-equal to the distance between the supportingsurfaces of thediscs 10, and the roll. This provides an arrangementin'which the flanges not only" provide means for securing thefrollparts together, but in which the peripheries of the flanges act as material supporting and conveying means. i
. The embodimentshown in Figure 2 is generally similarto thatrhereinabove described, but the: roll is divided into more than two parts, Theport-ionot the roll which is shown is divided. intov three parts 21, 22 and;23, and since Figure 2 illustrates substantiallyone half of the entirefrolh the; roll, according to found necessary or desirable. The roll parts I 21, 22 and 23 are provided with outwardly radially extending flanges similar to flanges 7 in Figure 1. The flanges'7atermir nate inhorizontal flanges 8a, the flanges a being united by bolts 9a. Projection and recess engagement constituting the projections 5a and the recesses 611 also is provided for fittin the roll parts together.
ntermediate the flanges 7a on the roll parts 22 and 23 are secured material conveying discs 25. These discs are made in two parts 26 and 27 secured together by bolts 28. Each art has a hub 29 which bears against the m l,a web 30, and a rim 31 which supports the material being conveyed through the furnace, The web 30 is provided with openings 32 to reduce the weightof the disc. In each of the embodiments, the adjacent ends of the roll parts are provided with outwardly extending flanges which not only pro vide means for securing the rollparts together, but also themselves act as material supporting and conveying means. The invention is particularly applicable to the production of rolls cast from an alloy having a high melting point, but it may be used irrespective of the material of which the rolls are made. I
\Ve have illustrated and described two preferred embodiments of our invention. It is to be understood, however, that the invention may be otherwise embodied within the scope oft-he following claims.
Weclaim: v 1'. Apparatus for conveying material through a furnace comprising a cast metal foil split transversely into a plurality of parts, material supporting discs spaced longitudinally of the roll, the roll having outwardly radially extending flanges thereon at the split, and means for connecting the flanges of adjacent roll parts. v
2. Apparatus for conveying material through a furnace comprising a cast metal roll split, transversely into a plurality of parts, material supporting discs spaced longitudinally of the roll, the roll having outwardly radially extending flanges thereon at the split, and means for connecting the flanges of adjacent roll parts, the flanges and acting as material supporting and conveying means. a,
s 3-. Apparatus for conveying material through ,a furnace comprising a cast metal roll spilt transversely into a plurality of parts and having outwardly radially extends ing flanges adjacent the split, and means for connecting the flanges of adjacent roll parts, the flanges being adapted to act as supporting and conveying means for the material.
4. Apparatus for conveying material through a furnace comprising a cast metal roll split transversely into a' plurality of parts and-having outwardly radially extending flanges adjacent the split, means for connecting the flanges of adjacent roll parts, ad-
roll parts'having projection and recess en gagement, material supporting discs of high melting point alloy spaced longitudinally of the roll, the outer surfaces of the discs and flanges extending substantially e ual distances from the roll so that the discs and flanges are adapted to support the material. 6. Apparatus for conveying material through a furnace comprising a roll split transverselyinto a plurality of parts, material supporting discs spaced longitudinally of the roll, the roll having outwardly radially extending flanges thereon at, the split, the outer surface of thediscs and flanges extending substantially equal distances from the roll so that the discs and flangesv are adapted to support the material, and meansfor connecting the flanges of adjacent roll parts. In testimony whereof we have hereunto set our hands.
