Description
Technical field
The present invention relates to a kind of method of pure titanium seamless tubes roll piercing, belong to metallurgical technology field.
Background technology
Pure titanium seamless tubes are produced typically using cold rolling or cold-drawing technology after circular pipe blank extruding.However, extruding exist cost it is high,
The low problem of lumber recovery.Extruding is substituted according to Mannesmann piercing mill perforation, production cost will be substantially reduced.Specifically, oblique milling is worn
Two rolls that hole machine is arranged by left and right, up and down vertically arranged two guide plates (godet) constitute totally enclosed pass, and oblique milling is worn
The concrete structure and working method of hole machine are prior art, and therefore not to repeat here.But because there is one layer of very thin oxidation on pure titanium surface
Film, this layer of oxide-film can be destroyed in plastic history, and the newborn pure titanium exposed is easy to be bonded above instrument and produced
Abrasive particle, influence forming process and product quality.When using Mannesmann piercing mill perforation pure titanium seamless tubes, two of Mannesmann piercing mill
Guide plate (godet) is easily adhered, and scabbing for being adhered on guide plate (godet) can scratch titanium tube surface, cause titanium tube to be scrapped.
The content of the invention
The technical problems to be solved by the invention are：A kind of method of pure titanium seamless tubes roll piercing is provided, can prevent from leading
Plate (godet) produces viscous titanium phenomenon.
It is to solve above-mentioned technical problem the technical solution adopted in the present invention：The method of pure titanium seamless tubes roll piercing,
Including step：
Step 1: first using sensing heating pipe, heating-up temperature is less than pure 5 DEG C~20 DEG C of titanium transformation temperature；Then use
Resistance wire furnace heats pipe, so that blank temperature is uniform, heating-up temperature is less than pure 5 DEG C~20 DEG C of titanium transformation temperature；
Step 2: opening the perforation that roll piercing unit carries out pure titanium seamless tubes；
Step 3: a diameter of 0.1mm~0.8mm ceramic rounded grain is incorporated into what roll was contacted with pipe by conduit
Position, roll bites after pipe ceramic rounded grain being pressed into pipe surface.Mill is contacted when pipe blank rotary and with guide plate (godet)
During wiping, ceramic rounded grain plays a part of isolation titanium tube base and guide plate (godet), so as to prevent guide plate (godet) from gluing titanium.
It is further：Sensing heating in step one is heated using line-frequency induction.
It is further：Ceramic rounded grain in step 3 is alumina particle.
It is further：Conduit in step 3 uses metal hose.
Sensing heating is first used in the present invention, its firing rate is fast, pipe oxidation is few, and pipe surface does not have oxide skin, because
This ceramic rounded grain is easier to be pressed into pipe surface；But induction heating temperature is uneven, thus using resistance wire furnace setting with
Sensing heating identical temperature, to heating of pipe blank, makes blank temperature uniform.Using the heating means of the present invention, heating can be improved
Efficiency, while so that blank temperature uniformly, does not influence product quality.
Mannesmann piercing mill is bitten pipe by roll when perforating, and drives pipe blank rotary to advance, and pipe is first bitten by roll,
It is rotationally advancing after a segment distance and is just contacted with guide plate (godet), titanium tube base and guide plate (godet) severe friction, causes to glue after contact
Ceramic rounded grain is pressed into pipe table by titanium, therefore, the present invention before pipe is not yet contacted with guide plate (godet) by roll
Face, prevents guide plate (godet) from gluing titanium using the buffer action of ceramic rounded grain.
Alumina high temperature does not react with pure titanium, is good isolation, lubricant, and cost is relatively low, therefore the present invention
Using aluminium oxide ceramics rounded grain.
The diameter of ceramic rounded grain is too small, does not have isolation, the effect of lubrication；Diameter is too big, it is difficult to be pressed into pipe table
Face, even if press-in, also easily comes off, therefore the diameter of the ceramic rounded grain in the present invention is preferably 0.1mm~0.8mm.
The beneficial effects of the invention are as follows：The phenomenon that guide plate (godet) is adhered when eliminating pure titanium seamless tubes roll piercing, is carried
High yield rate, so as to preferably enter eleven punch 11 using Mannesmann piercing mill hot rolling, can not only substantially reduce production cost,
And titanium tube defect is reduced, solve Mannesmann piercing mill guide plate (godet) in the technology of existing hot-puncturing process pure titanium seamless tubes and hold
The problem of easily adhering and cause waste product increase, provides a kind of new method, while using this hair for the production of pure titanium seamless tubes
After bright method, eleven punch 11 can be entered in the Hot Rolling Mill comprising Mannesmann piercing mill, tube reducing is determined, so that in a line of production technology
On directly produce high-precision pure titanium seamless tubes, solve in the prior art Mannesmann piercing mill guide plate (godet) easily adhesion and into
The problem of product rate is low.
