Titanium rod manufacturing requirements which

Titanium rod manufacturing requirements which, the current domestic production of titanium rod business a few, there are many such enterprises, many enterprises in Shanghai, but in the production of technical requirements, compliance is not a lot really, today Shanghai Tianyu Titanium titanium rod gave you talk about the technical requirements of production which:
A titanium rod manufacturing process
Titanium rod manufacturing generally need to go through three processes: forging → hot rolling → car light (polished)
1. Forging (hot forging): metal recrystallization temperature or higher, the forging process.
2. The hot-rolled (hot rolling): at a temperature above the recrystallization temperature of the rolling process.
3. car light (burnishing): polished is the use of a special rotating stick with abrasive grinding wheel (or belt) to cut metal parts of the surface of the process. Polished surface of the part can be removed burrs, rust, scratches, welding tumor, weld, trachoma, oxide and other macroscopic defects, to improve the flatness and plating quality parts.
Second, the implementation of international standards on the titanium bar stock
GB / 2965-2007, GB / T13810, Q / BS5331-91
Third, the production technology requirements
1. Chemical composition of titanium square tubing and titanium alloy bars shall comply with GB / T 3620.1, regulations, demand side reinspection, the chemical composition of the tolerances shall comply with the provisions of GB / T 3620.2 of.
Diameter or side length and tolerance rod 2. The thermal processing should be consistent with the provisions of one table.
3. thermal processing by car (mill) light bar and cold-rolled, cold-drawn bar diameter tolerances shall comply with the provisions of Schedule II.
4. thermal processing by car (grinding) roundness light bars should not half its size tolerances.
5. The process state does not cut length bar is 300-6000mm, annealed state bar not length length 300-2000mm, length or double length should be within the range of no definite length. Length Length tolerance of + 20mm ; double length rods should be included in the amount of incision, each cut the amount of 5mm. Length or double length should be specified in the contract.
