The production process of titanium bars and rods typically includes the following steps:

1. Raw Material Preparation:

   • The raw material is usually high-purity titanium blocks or ingots, where purity and chemical composition are crucial for the final product's quality.

2. Melting and Casting:

   • Titanium blocks or ingots are heated to their melting point and then cast into molds.
   • Casting methods may vary and include processes like vacuum melting, arc melting, or casting under an argon atmosphere.

3. Heat Treatment:

   • Castings undergo heat treatment, including solution treatment and annealing, to relieve internal stresses, improve grain structure, and enhance mechanical properties.

4. Hot Rolling:

   • Heat-treated castings are fed into rolling mills where they are pressed at high temperatures to the desired diameter and length of bar or rod.
   • During hot rolling, titanium bars or rods may undergo multiple passes of rolling and annealing to achieve the desired mechanical properties and microstructure.

5. Cold Working (Optional):

   • Some specific specifications of titanium bars or rods may require further cold working such as drawing, stretching, or cold drawing to improve dimensional accuracy and surface quality.

6. Surface Treatment:

   • Titanium bars or rods may undergo surface treatments such as polishing, acid etching, or sandblasting to improve surface finish and cleanliness.

7. Inspection and Quality Control:

   • After production, titanium bars or rods undergo rigorous inspection and quality control to ensure they meet specifications and quality requirements.
   • Inspections may include chemical composition analysis, mechanical property testing, dimensional measurement, and surface inspection.

8. Packaging and Shipping:

   • Qualified titanium bars or rods are packaged and accompanied by necessary quality certificates before being shipped to customers or further processed for use.

The above is a general production process for titanium bars and rods. Specific production processes may vary depending on the manufacturer, product specifications, and quality requirements.

Titanium bars and rods are elongated materials made of titanium, commonly used across various industrial sectors. Here are the general specifications, grades, applications, and characteristics of titanium bars and rods:
