This method is not suitable for extruding,copp b
of this type owing to,much.,higher extrusion

PERIODICAL: Tsvetnyye metally, 1961,,No. 4, pp. 51-58
TEXT: As a result,of improvements ln~the roll pass design and
.rolling techniques (Refs. 15 '22) theproductive capacity of cold,
reducing mills has increased to such an extent-that cold1reducing
can now compete with cold'drawing. However, analysis,of
operational,data indicates,tha.t~ the productive capacity of cold.
reducing mills could be further inereased.,by,20-30%. In the,present
an attempt is,made-analytically to establish the means by'
which this increase can beattained and to provide a.theoretical.
basis for determining the maximum productive capacity of,:a mill,
either from thelcharacteristics ofthe mill-, or. from the properties~
of the metal rolled. The-argument presentedby the authors'is
based on the relationship between;the, roll pass design and.various.

the same manner as the elongation 6, and the reduction of

ABSTRACT: The authors enumerate, some disadvantages of recentl

long rectangular tubes with a round bore. They~sta.te
that investigation has enableda system free-from these
effects to be devi.sed,which has been adopted at the

enabled the shape and.dimensions of the initial billet

uniformity of deformation and base their treatment of
a rectangular tube with a round bore on certain similar-_
to the rolling of rectangular-,bore,rectangulT
tubes (Figure 1). They split the cross-section of the
tube and billet into a series of areas to examine
geometrical contours. Deducing the conditions for.pro-,

bore rectangular billets, the authors show:(Figure

PERIODICAL: TsvetnyyeMetally, 1958, No.1, pp. 81 83 (USSR)
ABSTRACT: The authors discuss the effects of roll wear and of
incorrect setting on the size of the gap round the outside of
the pass (Fig.1) and on the metal pressure on the rolls. They
go on to consider tube-wall deformation, showing a graph of
changes in relative deformation and metal pressure with a
tapering gap for the alloy J168. They state that-with aluminium.
alloys such as LU 2 A16 or J10?0, such a gap can,lead to the
formation of tian'sverse Icracks in.the tubes. After considering
ways of minimising passwear,in working rolls, the authors
suggest that wall-thickness tolerances of the tube billets can
be increased to + 15%.

TEXT: As a result,of improvements ln~the roll pass design and
.rolling techniques (Refs. 15 '22) theproductive capacity of cold,
reducing mills has increased to such an extent-that cold1reducing
can now compete with cold'drawing. However, analysis,of
operational,data indicates,tha.t~ the productive capacity of cold.
reducing mills could be further inereased.,by,20-30%. In the,present
an attempt is,made-analytically to establish the means by'
which this increase can beattained and to provide a.theoretical.
basis for determining the maximum productive capacity of,:a mill,
either from thelcharacteristics ofthe mill-, or. from the properties~
of the metal rolled. The-argument presentedby the authors'is
based on the relationship between;the, roll pass design and.various.

the same manner as the elongation 6, and the reduction of

PERIODICAL: Tsvetnyye Metall,y, 1958.9 Nr 1.2, pp 70, - (-USSR)
ABSTRACT: The authors enumerate, some disadvantages of recentl
described (Ref 1) roll_paas~designs for producing 18-m
long rectangular tubes with a round bore. They~sta.te
that investigation has enableda system free-from these
effects to be devi.sed,which has been adopted at the
"Krasnyy Vybo rzhets'l.-Works, has led to a better billet and.,
enabled the shape and.dimensions of the initial billet
to.be determined. They consider thatinrolling shaped.
profiles,,the.aim.should be to reduce to a minimum non-
uniformity of deformation and base their treatment of
a rectangular tube with a round bore on certain similar-_
to the rolling of rectangular-,bore,rectangulT
tubes (Figure 1). They split the cross-section of the
tube and billet into a series of areas to examine
geometrical contours. Deducing the conditions for.pro-,
ducing rectangular tubes wi-th minimal ovality from round-,;
bore rectangular billets, the authors show:(Figure

the influence on this of wall thickness. They go.on-to
dis 'the- selectio g e h
cuss ir n of~billet~form (Fi ur 4) and t e
pass design (Figur e 5). The~doption of this pass design
increased mill,productivity by more.than 1,5 times, the
load on the mill being simultaneously reduced and better
tube dimensions, pass durability and billet. pressing were
the result. Figure 6 shows the metal pressure in'the
roll along the length of the groovewhen rolling coppers
rectangular 36 x 16 x 16 mm tubes, Figure 7 showing the
.Corresponding deformations, The authors give the pass
design (Figure,8) for rolling 16-18 m long square tubes
from a round billet~anddetails of the calculatlons. They
go on to.consider the applicability of drawing to producing
round-bore square tubes',giving several schedules
(Tables 1,2) and the pass design for 10 x 10 mm tube with
a 6 mm bore. The---~:are.9 figures, 2 tables.and-

PERIODICAL: TsvetnyyeMetally, 1958, No.1, pp. 81 83 (USSR)
ABSTRACT: The authors discuss the effects of roll wear and of
incorrect setting on the size of the gap round the outside of
the pass (Fig.1) and on the metal pressure on the rolls. They
go on to consider tube-wall deformation, showing a graph of
changes in relative deformation and metal pressure with a
tapering gap for the alloy J168. They state that-with aluminium.
alloys such as LU 2 A16 or J10?0, such a gap can,lead to the
formation of tian'sverse Icracks in.the tubes. After considering
ways of minimising passwear,in working rolls, the authors
suggest that wall-thickness tolerances of the tube billets can
be increased to + 15%.
There are 6 figuFes.
