Abstract
The invention discloses a method of producing TA10 alloy wire rods through a high-speed wire mill. Square TA10 alloy billets produced by an electron beam cold hearth are placed into a heating furnace of the high-speed wire mill to be heated after undergoing surface milling, chamfering, surface coping, flaw detection, top cropping and anti-oxidation layer coating, and the heads of the square billets are cut off after the square billets undergo rough rolling of 6-7 times to obtain small square billets; the small square billets undergo precision rolling of 11-12 times, then a laying head is used for laying TA10 alloy rings, the TA10 alloy rings are air-cooled, conveyed to a coil collection cylinder for coil collection and then naturally air-cooled to normal temperature, and therefore the TA10 alloy wire rods are obtained. According to the method, piece weight of the TA10 alloy wire rods can reach 1000 kg, the production cost is low, the production cycle is short, the surface quality is high and the performance is excellent.
Description
Technical field
The present invention relates to titanium alloy dish circle production method technical field.
Background technology
TA10 (nominal component is Ti-0.3Mo-0.8Ni) is not because containing your element rare, good processability, and the corrosion resisting property in reductant and high-temperature chlorine compound is significantly improved than pure titanium, can partly replace Ti-Pd alloy.TA10 alloy has been considered to the most excellent new type corrosion resistant alloy since Ti-Pd alloy, may occur in the environment of crevice corrosion at some pure titaniums, and TA10 alloy will replace the acquisition of pure titanium and apply very widely.Need to be smelted into ingot blank through VAR stove in the production method of traditional TA10 alloy wire, silk, strip off the skin, cogging forging, decaptitate tail, flaw detection, secondary strips off the skin, secondary decaptitates the operations such as tail, it is high that this production method has energy consumption, labour intensity is large, the shortcomings such as production efficiency is low, and product size fluctuation is large, type quality difference.In recent years also occurred adopting hot rolling to produce the method for titanium or titanium alloy rod, line, the method of three-roller Y shaped tandem mill rolling titanium or titanium alloy Bar Wire Product disclosed in a kind of pure titanium rod, wire rolling method, CN200610069108.1 disclosed in Chinese patent CN200610044633.8, these two kinds of methods all only need once heat, and realize continous way production, product substance reaches 50 ~ 100kg, compares traditional product through forging or technique of swaging and is enhanced in energy consumption, production efficiency and dimensional accuracy.But still the titanium alloy wire market demand and user that day by day strengthen can not be met to monovolume weight demands.CN201210518979.2 discloses the production method of industrial pure titanium wire rod, requires and user's monovolume weight demands for product quality, produces the pure titanium wire rod that monovolume weight can reach 400kg, and the quality of titanium wire rod is greatly promoted.But its raw material adopted need forge through cogging, secondary strips off the skin, to decaptitate the operations such as tail, not only add production cost, also cause the huge waste of human and material resources, lumber recovery is declined greatly, also may because the reason be mingled with of raw material cause fracture of wire, the deficiency such as disconnected thin in follow-up drawing process.
Summary of the invention
The object of the invention is to solve the deficiencies in the prior art, provide a kind of production cost lower, have good rolling mill practice and production capacity, production operation is convenient, rolling reel circle quality is out good, effectively can solve traditional handicraft adopts forging blank specification little and the high-speed rod-rolling mill of the problems such as Repeat-heating, finished product structure property be uncontrollable in the operation of rolling need produce the method for TA10 alloy disc circle.
In order to achieve the above object, the technical solution used in the present invention is as follows:
High-speed rod-rolling mill produces a method for TA10 alloy disc circle, comprises the following steps:
(1) TA10 alloy square billet electron-beam cold bed furnace produced is put in high-speed rod-rolling mill heating furnace and is heated after milling face, chamfering, figuring of surface, flaw detection, crop, painting antioxidation coating, and the heat time is 220 ~ 300min;
(2) TA10 alloy square billet is carried out 6 ~ 7 passage roughing, rolling temperature is 870 ~ 930 DEG C, excises, obtain small billet to the head of square billet after roughing;
(3) small billet after roughing crop is carried out 11 ~ 12 passage finish rolling, 1st ~ 6 passage final rolling temperatures are 850 ~ 910 DEG C, and 6th ~ 12 passage essence temperature are 820 ~ 890 DEG C, and finishing speeds is 60 ~ 120m/s;
(4) the TA10 alloy Laying head through finish rolling is told into TA10 alloy ring, laying temperature is 850 ~ 870 DEG C;
(5) TA10 alloy ring is delivered to air-cooled line air-cooled, the temperature of air-cooled rear TA10 alloy ring controls at 530 ~ 550 DEG C, and after then delivering to Ji Juantongji volume, natural air cooling is to normal temperature, obtains TA10 alloy disc circle.
TA10 alloy square billet described in above-mentioned steps (1) through milling face, crop is processed as the square billet that cross section specification is 150 ~ 210mm × 150 ~ 210mm, length 8200 ~ 9500mm; High-speed rod-rolling mill heating furnace adopts Three-section type heating, and wherein one section is first rolling section, and heating-up temperature is 930 ~ 950 DEG C; Two sections of heating-up temperatures are 910 ~ 930 DEG C, and three sections is rear rolling section, and heating-up temperature is 880 ~ 900 DEG C; The angle of square billet chamfering is 45 ° ~ 48 °.
The present invention adopts electron-beam cold bed furnace to produce TA10 alloy preform, only need can enter rolling process after simple milling face, reconditioning operation, after avoiding the operation of series of complexes such as carrying out cogging forging, secondary reconditioning and strip off the skin of still needing after conventional method produces ingot casting, just can be rolled operation.In addition electron-beam cold bed furnace has the effect of refining, purification, can produce the high-quality TA10 alloy blank be mingled with without high/low density, and good all than forging base of blank indices, for the Continuous maching of silk, wire rod is below provided convenience.
The substance that the inventive method produces TA10 alloy disc circle can reach 1000kg, surface quality is high, can obtain desirable metallographic structure and physical property by the control of cooling blower, can produce monovolume weight and reach more than 1000kg dish circle, lumber recovery is high, can obtain obvious economic benefit.The inventive method technique is simple, easy to operate, result of use is good, when ensureing TA10 alloy surface quality and physical property, production procedure being shortened dramatically, greatly reduces production cost.
