A054/A127 and partly on theXIIT -75 (KhPT-75) and XIIT-32 (KhPT-32) stands, with tubes 21 x x 1.5 mm in size [93 x (6 - 8) mm ~ 53 x 3.5 mm ) 21 x 1.5 mm]. it was found that reducing the number of passes improved the tube quality and rendered the finishing of the inner tube surface more easy. The power consumption for deformation and the tool consumption dropped (the latter by 20 - 25%). When rolling 70 x 6 0 38 x 2 mm tubes, cracks appeared in the finished tubes, due to tension stresses. These could be eliminated by turning over the tube twice on the KhPT-5c' stand, which made it possible to increase the feed from 9 - 10 mm to 10 - 12 mm. When rolling 21 x 1.5 mm tubes according to this new method, buckles were cbserved on the tube surface, mainly caused by the great conicity of the mandrel and the groove width. To prevent these defects, the conicity of the mandrel was reduced to 0-03 and a considerable draft was applied at the be- ginning. Thus, buckles no longer formed and the output of the KhPT-55 mill was raised by 20% (ti-eyield of grade-I product was 84% instead of 57% obtained when the first modification of the process was used). The consumption of grjove pairs during 6 months was 169 instead of 206 (with the old method), while, moreover, the number of mandrels required decreased from 1,747 to 1,505 during the same period. However, the new rolling process requires material of high ductility.

The maximum compressive forces acting,on the tube do not exceed 10% of the total roll pressure in rolling standard-sized tubes; this value can be doublel or t"reblgdwhen thin-walled tubes are rolled. This means that in some cases the axial loads during rolling of thin- walled tubes could exceed the yield point of the m'etal with resultant damage to the end portion of the tube. Both the roll pressure and the axial loads can often be sufficiently reduced bythe application of efficient lubricants such as MoS 2* When further reductions in roll pressure and axial loads are necessary, they can be attained by the following means: a - rotating the tube twice, i.e. before both the forward and reverse movements of the carriage; b - changing the radius (~JL,_, of the pitch circle of the driving gear; the optimum ratio (whare COO is the radius of the roll) has been found to be approximately 1,1. 3) High quality of the final products can be attained by: a - using a mandrel with a Card 2/3 SHEVAKIN, Yu.

Three different kinds of roll passes obtained from three different empirical formulae proposed by different investigators were made. The roll pass geometry is defined in an illustration and accompanying table and the three formu .I.ae*are recited. The rolling was carried out on mandrels with a 0.01 taper using BTI-1 (VTI-1), ()T4 (OT4) and 6T5-1 (VT5-1) titanium alloys. The pressure on the rolls, the total displacement, the rate of feed and the actual change in the wall thickness along the length of the roll pass were measured. The test results and their discussion have shown that a formula proposed by Yu.F.Shevakin et al.(Stall, !10.5, 1957) ensures a variation of the relative reduction along the Card 1/2 SHEMIN, YU.

Protsessy prokatki. 405-412 TEXT: The importance of a large reduc'tion in the beginning of the swaging portion of 4 die groove in tube rolling to achieve high productivity and good quality final tubes is discussed. The maximum possible reduction is desirable which can be determined from the knowledge of the mechanism of plastic.deformation. Three kinds of tests were carried out: (1) compression tests to destruction between flat strikers of the press on sockets made of OT4 alloy having a diameter of 46 mm, a wall thickness of 4 mm and a length of 50 mm; (2) compression of sockets between strikers with a round groove having a diameter of 40 mm; (3) different reductions of diameter in the beginning of the die groove during cold rolling of tubes. Starting with blanks measuring 46 x 4 and 50 x 1k mm of BT1-1 (VT1-1), OT4 and E~T5-1 (VT5-1) alloys to Card 1/2 S/848/62/000/040/005/005 On the plastic deformation ... E193/E48i be rolled into 30 x 2 Rill, tubes, the diameter reductions ranged between 1.11 an(I 8.1 mitt. Conclusions: The roll passes for cold rolling of tubes of metals and alloys with a hexagonal crystal lattice (magnesium, titanium, zirconium and tantalum) as well as of h*eat resistant alloys and alloys with low ductility which constitute solid solutions, must be so arranged that the initial reduction is about 3 to 6c,01. It is believed that as a result of self-diffusion in the direction of the stress gradient, which may lead to the formation of a new phase near the slip planes, the deformation may otherwise become difficult. For a given total deformation, a certain ratio between the relative diameter and wall thickness changes must be preserved, e.g. for a wall thickness reduction of 50% the diameter reduction ratio must not exceed 1.35.

TITLE: Forces on the ram during tube extrusion,- SOURCE: Tsvetny*ye metally*, no. 2, 1,-J14, 70-75 TOPIC TAGS: Extrusion, extrusion force, tube extrusion, ram, design, upsetting, ram stress, ram compression, ram stretching force ABSTRACT: Measurements were made of forces applied to 15, 26, 45 and 55 min. dia-aeter rams used in extruding tubes having 2,3,4, and 6 mm. walls from 150 x 200 mm. copper billets on a 1500 ton horizontal press. On upsetting the billet the forces on the ram Increase to a maximum and then decrease as it approaches the die. The upsetting proceeds in two stages characterized by reverse flow of the metal which is progressively retarded by frictional forces until the defor- mation of the ingot is caused by shearing of the non-upset portion of the billet at the bottom. The nature of the change in stresses on Card 1/3 ACCESSION 1R.: AP4015112 the ram along the length of the Ingot and the position of the maximum E5 stress depends on the ratio of the ram and the container diameter. As the diameter of the ram decreases, the position of the maximum stress shifts In the direction of the die. The total of the stresses on the raTa, a, , is the sum of the stresses due to the cutting forces, e', and the frictional forces, 6": 6-= Z( 6,,+ e"), Z being the temp- erature coefficient accounting for the cooling of the metal (1i its uf 1.0-1.6). The force on the ram may be expressed by 2 = DTd /4) The compression stresses on the ram decrease as its diameter increa- ses, e.g. increasing the diameter from 15 to 55 mm. reduces stresses from 45 to 25 kg/mm2. Resistance to deformation increases on transi- tion from upsetting to extrusion, and the friction increases until it is the only force on the ram as the metal flows through the die. The forces on the ram are less with a larger diameter ram and a tube with thicker walls. Stretching forces are developed on the ram on remov- ing it at the end of the extrusion. As a result of these investiga- tions a new ram has been constructed (Shevakin, Yu. F., Ry*tikov, A.M. and Xoshurin, A.V., inventor certificate No. 143009) comprising the combination of a larger removable ram and a smaller operating ram Card 2/3 ACCESSION NR: AP4015112 which Is lon-er than -oresent rams.

To determine the plastic properties of pipe billets from AMG6 alloy, samples were subjected to tensile tests at temperatures between 20 and 325C on a MiPT-75 mill provided with a special heating system. It was found that ATIAG6 alloy can be succiUsfully rolled in the annealed state at 120420C; in the nonannealed state, it is necedsary to raise the Iciver limit of the temperature interval to 150C.

Samples of both types (after quenching from 1100C) were tested in a Chevenard tensile strength machine. It was found that after, rolling the properties of the metal itself and of the welded seam. are identical. Metallo- graphic analyses ~,~zhowed that the basic metal and that of the seam have the same structure. Samples were rolled at different deformation rates. It was found that Immediately after welding and quenchft from 1100C, the tensile strength and the relative elongation of the welded seam is lower than that of the basic metal. Quenching improves the plastic properties of the seam but lowers its tensile strength.

Tsvetnaya tallurgiya, no. 1, 1965, 136-141 -TOPIC TAGS: metal tubei metal rolling, plastic deformation .ABSTRACT: The fundamental characteristics of the tube rolling process are experi- metally studied using stock with dimensions of 146 x5.5-8 mm. The rolling was done, .by a driven mandrel with non-driven rolls. The working rolls were located on op- posite sides of the workpiece and had a complex shape consisting of a cylindrical 1 .Supporting section, a collar, a cylindrical grooving band and a tapered tail see- .tion. The axial feed of the workpiece, the angle of the r*ll flange and the abso_ :lute reduction in wall thickness were varied within wide limits during the rolling ,process. An oscillographic record of the force parameters was kept by using strain:--- !gauges and amplifying equipment. Deformation was studied by determining the dimen-! sions of the tube before reaching the deformation point and the tube dimensions at .the point itself. The hardness of the metal was measured with respect to thickness:- i Card ;L 1364-66 ::ACCESSION XR: AP5013074 !and length of the specimen. Analysis of the experimental data indicates that when ;reductions in wall thickness are small and roll collar angles are large, axial ;stresses arise in the metal ahead of the collar which exceed the shearing strength i ~of the metal. Thus the surface metal is sheared off and there is a buildup ahead .of the roll flange. This metal buildup (increase in wall thickness) reduces the axial stresses, and equilibrium is reached at the deformation point when the stress- es reach a certain minimum value. The metal buildup increases the dimensions of .the deformation source causing nonuniformity in deformation of the metal with re- spect to thickness. Outside the contact zone, the length of the workpiece is re .duced and the cross section is increased, while at the deformation point there i; an increase in the length of the specimen and a reduction in tubular cross section.! 'This type of deformation increases energy consumption since the contact surface may! ,be doubled. Orig.' art. has: 5 figures, 1 table.

TITLE: Stresses accompanying the rollin /of preheated aluminum-alloy tube SOURCE: Tsvetnyye metally, no. 10, 1965, 72-75 TOPIC TAGS: metal rolling, aluminum alloy, metal tube, induction furnace u r ABSTRACT: Since Alferova and Ost-in (Byull IsIINCh~',* no 7 (387)) showed that' in the rolling of staiiil-ess-steW tube, preheating assures a reduction in the pressure exerted by metal on the rolls', the authors experimented with the rol- ling of preheated AMg6 (aluminum-alloy) skelp (preheated at tempgatures of 25,'* 100, 150, and 200*C) in a specially adapted KhPT-75 rolling milll'bequipped with an induction heating installation. The total pressure exerted by the metal on the rolls and the axial stress sustained by the skelp were measured by methods des- cribed elsewhere (see, e.g. Shevakin, Yu. F. Kalibrovka i usiliya pri kholodnoy prokatke trub, Metallurgizdat, 1963). Contrary to the expectations, it was found i that the pressure exerted by the metal on the rolls increases rather than de- 1/2 Card L 3497-66 ACCESSION NR: AP5024861 creases with increasing preheating temperature. This is chiefly attributable to the insignificant differences in the strength properties of AMg6 allmy over the temperature range investigated and the increase in frictioxi- & ent with in- creasing preheating temperature of the akelp, owing to the partial burnout of the lubricant. This is accompanied by a decrease in the total axial stress as well as in torque and hence also in the expenditure of energy on deformation of the metal.
