Sponge titanium is a raw material for processing materials of pure titanium and titanium alloys. There are many possible ways to prepare titanium metal from titanium-rich ore containing TiO2. Metallurgists believe that the best way to prepare pure titanium is to convert TiO2 into TiCI4, and then use TiCI4 as raw material, or reduce TiCI4 with sodium (called sodium thermal reduction method or Kent method "ie SL" method); or use magnesium The titanium block produced by thermal reduction of TiCI4 (called magnesium thermal reduction method or Krauer method) is named sponge titanium because of its porous appearance.
The titanium rod production process is to melt and cast sponge titanium into ingots, and then produce titanium rods through billeting, forging and grinding. Sponge titanium is the most primitive material for producing titanium, and smelting it will get the initial material for titanium processing - titanium ingot.
- Press the electrode, press the sponge titanium through the press to form a dense sponge titanium pressing block electrode;
- Vacuum casting, under the conditions of 1700~1800℃ and -103Pa, vacuum casting the above-mentioned sponge titanium compact electrode for three times;
- Billeting, under the condition of 1000°C, the billet is opened by a hydraulic press, and finally pressed into a square billet; it is introduced that the forging temperature and the degree of deformation are the basic factors that determine the structure and properties of the alloy. The heat treatment of titanium rod is different from that of steel, and die forging is usually used to make a shape and size close to scrap. It does not play a decisive role in the structure of the alloy. Therefore, the process specification of the final step of the titanium rod plays a particularly important role. It is necessary to make the overall deformation of the blank not less than 30% and the deformation temperature does not exceed the phase transition temperature. In order to obtain high strength and plasticity of the titanium rod at the same time, and the temperature and deformation degree should be distributed as uniformly as possible in the entire deformed blank.
- For the first titanium rod rolling, under the condition of 970~980℃, it is preliminarily rolled into a cylindrical shape blank with a rolling mill;
- The second titanium rod rolling, under the condition of 950 ° C, is rolled into a blank with a rolling mill.
- Annealing, titanium rod annealing includes stress relief annealing, complete annealing, and double annealing, isothermal annealing, vacuum annealing and other process methods.
- Peeling and polishing, peeling and polishing is a precision process that changes the surface morphology of titanium rods
