Description
Technical field
The invention belongs to metallurgical technology field, in particular to a kind of thin-walled TC4 titanium alloy seamless tube and production method thereof.
Background technology
Along with the fast development of Chinese national economy and science and technology, titanium alloy material technology of preparing and quality product are greatly improved, and have driven the rapid expansion of titanium alloy Application Areas, the demand of high-strength titanium alloy pipes are got more and more in recent years. Because TC4 titanium alloy is expensive, and intensity is higher, it is generally desirable to using thin-wall seamless pipe, wall thickness is below 3 millimeters.
Existing titanium alloy seamless tube generally adopts hot rolling or cold rolling production.
Patent 103128102A discloses the production method of a kind of titanium alloy oil well pipe, this production method comprises: vacuum oven twice melting, repeatedly skin one-tenth circle base is taken off in forging, it is heated to 970-1030 DEG C through ring furnace, hot piercing obtains hollow billet, and hollow billet enters five frame three-roller continuous rolling mills after high-pressure water descaling, and even rolling coefficient of extension is 2.5-3, reducing rate is 15%-25%, obtained waste pipe; Again famine pipe being entered sizing mill group, determining footpath coefficient of extension is 2-2.2, and reducing rate is 45%-52%, obtains the hot seamless tube of external diameter 88.9mm. Again hot seamless tube is heat-treated, it is heated to 950-980 DEG C of insulation and obtains finished product in 1-1.5 hour. The method adopts the mode of hot continuous rolling to carry out the manufacture of titanium alloy seamless tube, its titanium thickness of pipe is thicker, lumber recovery is low, and cause that interior outer surface quality is poor, defect is many because of the existence of interior outside surface gas-permeable layer, especially defect in inner surface, it is difficult to remove, in addition, after rolling, also needs thermal treatment process just can obtain finished product.
Patent 103722043A discloses production method and the detection method of a kind of titanium alloy seamless tube, and its production method comprises the following steps: raw-material preparation; Heating; Forging; Cold rolling; Cold-drawn; Aligning; Vacuum annealing; Shaping. The method can produce qualified product, but its complex procedures, cost height, it is necessary to vacuum annealing just can reach the performance of product requirement.
Visible, only can not obtain thin-wall seamless pipe by hot rolling, generally need that perforation+multi-pass is cold rolling or cold-drawn, all need first to anneal before every time cold rolling or cold-drawn, cold rolling must subtract footpath while just can subtract wall, therefore the external diameter of hot-rolled tube must be enough big; Cold-drawn requires that unit elongation is greater than 20%, and the unit elongation of TC4 titanium alloy generally can reach. And, existing hot rolling titanium pipe lumber recovery is low, and causes that interior outer surface quality is poor, defect is many, especially defect in inner surface, it is difficult to remove because of the existence of interior outside surface gas-permeable layer. Cold rolling or cold-drawn titanium pipe complex procedures, cost height, output is low, and needs vacuum annealing just can meet the requirements of performance.
