The temperature-controllable of a bringing-up section.It is reducibility gas atmosphere in heating of pipe blank stove 1,1 heat stepwise pipe of heating of pipe blank stove is described
Heat stepwise includes preheating section, bringing-up section and soaking zone, and preheating section blank temperature is 500-650 DEG C, and preheating time is generally 30-
90min；Bringing-up section blank temperature is 650-1100 DEG C, heating time 60-90min；Soaking zone blank temperature is 1100-1150
DEG C, soaking time 60-150min, drop temperature is 950-1120 DEG C；Heating time and pipe outer diameter are related greatly.Drop temperature is
950-1120 DEG C, at this time titanium alloy be in β phase regions, resistance of deformation K is about 65-120MPa.
D, two roller small-angle guide-roller type punches, 2 drilling/rolling, hollow billet temperature is 900-1000 DEG C after perforation.
Feature 1：Roll uses small-angle tapered roller.Roller shape influences metal flow direction when barrel roll rolls, to metal stream
It is dynamic to form reaction force, it is unfavorable for metal flow, is also easy to produce infolding phenomenon.Appearance in pipe is easily formed during barrel roll rolling simultaneously
Surface helix line.Tapered roller is five sections of roller shapes, there is rolloff band, solves the problems, such as barrel roll helix, while tapered roller body of roll edge is rolled
The component velocity in line direction processed gradually increases, and adapts to the speed of pipe and increases, does not have reaction force to pipe.Bullet based on titanium alloy
Property modulus be about the 1/2 of steel, poor rigidity, mutability should not make thin-wall tube, therefore use small-angle tapered roller, 8-12 ° of feed angle
It is adjustable, 5 ° of fixations of rolling angle.To prevent titanium alloy from generating processing hardening phenomenon in the operation of rolling, rolled, rolled using the slow-speed of revolution
Roller rotating speed 40-80r/min is adjustable, roll rotational speed 40-60r/min when stinging pipe, and the seamless hollow billet of titanium alloy is made；
Feature 2：Since titanium chemical affinity is big, easily sticking phenomenon is generated with tool friction surface.Two roller conelets of titanium alloy tube
Angle guide-roller type punch substitutes the upper bottom guide that conventional through-hole machine uses using upper and lower guide wheel, efficiently solve titanium alloy due to
Friction between rolling tool and the metal sticking phenomenon generated, upper and lower guide wheel drive screw in copper spiral shell by motor via reducer
Rotation realizes pressure and rises to adapt to different pipes in mother；
Feature 3：Titanium chemism is larger, is easily chemically reacted with water and steam, generates cementation zone, easily causes simultaneously
Hollow billet surface fine crack.Roll cooling is cooled down using high-pressure water mist in the operation of rolling, and arrangement is as shown in Fig. 2, nozzle
Far from rolling entrance, ensure that roller roll surface in rolling is dried.
E, outer diameter and wall-thickness ratio are D/S after drilling/rolling, and as 10≤D/S ＜ 20, thick-wall titanium alloy is seamless, and hollow billet is straight
Shifting pipe device immigration subsequent processing was connected to be rolled；As 20≤D/S≤40, thin-wall titanium alloy is seamless hollow billet in transition again
950-1050 DEG C is reheated in heating furnace 3, then is rolled by moving pipe device immigration subsequent processing；
F, three-roll pipe mill 4 rolls：
Three-roll pipe mill by three belt roller shoulders the vertex being arranged in using roll line as the equilateral triangle of the centre of form, roll axis with
Roll line is into two angles of inclination.Roll axis tilts a feed angle in vertical direction and roll line, for realizing that spiral is rolled
System；Interlock a roll off angle with roll line in the horizontal direction.In the pass surrounded in three rolls and a plug, by perforating
The hollow billet sent is sleeved on long plug, is sent into pipe mill and rolled with supply bobbin device；Hollow billet is in deformed area through biting, subtracting wall（Together
When tube reducing）, it is smooth and return circle and as hollow forging.During oblique milling screw rolling metal in deformed area by the period of roll and plug
Continuous action and the variation for generating shape and size.Deformation of rolled wire be actually from justifying to justifying triangle again to round process.
It is than three-roll pipe mill advantage with two-roller mill：Product accuracy is high, because of the oblique milling of cored bar, in a time
Multiple spreading effect, greatly improves wall thickness accuracy；Flexibility is big in production, and pass ruler just can be changed by the clutch of roll
It is very little, it has an enormous advantage to tissue production；Deposit of tools quantity is few.
When rolling titanium alloy tube, roll is in low speed rotation before starting to bite, after hollow billet enters roll with plug
Start once to bite, titanium alloy tube hollow billet is only diametrically being compressed at this moment, as steel pipe advances, is opened in the shoulder of roll
Beginning hollow billet inner surface contact mandrel surface carries out subtracting wall, realizes secondary bite.It normally bites rear roll rotational speed and is increased to setting
Mill speed carries out high-speed rolling.Roll rotational speed drops back to low speed after the end of rolling.Usual biting speed is mill speed
70% 。
In the titanium alloy tube for producing D/S ＞ 16, to prevent hollow forging front end from generating flare, stung in hollow billet by roll
Before entering, topping roll is under the action of quick-opening device, and roll gap is more slightly larger than normal rolling roll gap, when the shoulder that hollow billet head passes through roll
Afterwards, topping roll quickly recovers to normal rolling position.It is about 0.3 second to depress actuation time.
Titanium alloy tube is 0-6 ° adjustable with 4 roll off angle of three-roll pipe mill, feed angle：0-12 ° adjustable, and feed angle increases, and rolls
Muzzle velocity processed is accelerated, and expanding value increases, but as the increase of feed angle, rolling stability reduce, wall unevenness is in increase
Trend easily generates internal thread.Therefore it is sent when producing thick-walled pipe using larger feed angle, thin-wall tube production using smaller
Into angle.But feed angle is also unsuitable too small when producing thin-wall tube, because feed angle is too small, mill speed is slow, especially thin-walled
Guan Shi, rolling time is long to be easy to cause the increasing of steel pipe head and tail temperature difference, the wall unevenness being formed on length of steel pipe direction.
Influence of the roll revolution to steel pipe is consistent with the influence of feed angle.In the case of in view of milling train force-power parameter,
When rolling titanium alloy tube, relatively low 8-10 ° of roll revolution 60-120r/min and smaller feed angle should be used, rolls titanium alloy
The seamless hollow forging of titanium alloy is made in pipe speed 0.22m/s~0.50m/s.
Three-high mill strictly controls roll cooling water, the roll type of cooling and piercer roll cooling side in the operation of rolling
Formula is identical.

When temperature to waste tube outer surface and the inner surface temperature difference is not more than ± 10 DEG C, hollow forging passes through Pierced billet reheating furnace 6 into follow-up rolling process；
When hollow forging does not need to carry out ageing treatment, hollow forging is directly through Pierced billet reheating furnace 6 into follow-up rolling process.
H, stretch reducing machine group 7 rolls：
The process that the process subtracted is a hollow body tandem rolling is opened, other than playing sizing, also requirement has larger reducing rate,
In addition to this, stretch reducing also requires to realize the purpose for subtracting wall by establishing tension between each rack.
Hollow forging is come out of the stove after reheating electric furnace and being heated to 950 DEG C, is exported in furnace delivery table and is carried out surface temperature measurement.Titanium alloy tube
Driven separately is used with stretch reducing machine group 7, because being determined the characteristics of collective's differential gearing cannot come by adjusting main Overlap electric machine
Each rack is made to reach an ideal speed, ensures that titanium alloy tube does not occur processing hardening phenomenon in the operation of rolling.So rolling
