Description
Technical field
The invention belongs to titanium alloy rolling technical field, is related to a kind of production method of copper composite ti pipe.
Background technology
In recent years, because titanium alloy has high intensity ratio, higher corrosion resistance, it is widely used in industry-by-industry,
Especially aerospace field.Titanium tube production generally uses cold-rolling process at present, and its plastic history and bar exist obvious
Difference；In some HTHP occasions of chemical industry, it is necessary to which the intensity of pure titanium tube reaches higher level, in order to ensure that tubing is enough
Voltage endurance capability, it is necessary to increase tube wall thickness；But when strengthening wall thickness, production is more difficult, and finished product rate is relatively low.
The content of the invention
It is an object of the invention to provide a kind of production method of copper composite ti pipe, solves current titanium tube production difficulty, into
The problem of product rate is relatively low.
The technical solution adopted in the present invention is a kind of production method of copper composite ti pipe, to specifically comprise the following steps：
Step 1, bar stock is processed into the forging of titanium ingot, bar stock is then squeezed into titanium tube base；
Step 2, using cold-rolling process by billet production into titanium tube；
Step 3, titanium tube is coaxially socketed with copper pipe, and one end of titanium tube and copper pipe is bolted, form copper titanium
Composite pipe blank；
Step 4, composite pipe blank is rolled, straightening processing.
The features of the present invention also resides in,
The welding material wherein used in step 3 is aluminium Si solder.
Wherein step 4 preheats before rolling to composite pipe blank in heating furnace.
Wherein preheating temperature is 250~350 DEG C.
Wherein in step 4 rolling include the passage of roughing 3~6, in roll 4~8 passages, the passage of finish rolling 4~8.
The invention has the advantages that titanium tube is socketed in copper pipe in the present invention, the wall thickness of pipe is added, while by copper
Pipe is fixedly connected with titanium tube one end, is avoided copper pipe and is relatively moved with titanium tube in the operation of rolling, is entered before the rolling
Row preheating, is advantageous to improve the ductility of tubing in the operation of rolling, and it is difficult that the present invention solves the production of current titanium tube, yield rate compared with
The problem of low.
