The core of titanium bar forging is to obtain high-precision, high-performance titanium alloy bars through high-temperature plastic deformation, which mainly consists of four key steps: melting, forging, rolling, and machining. The specific process selection depends on the product requirements, and common methods include open forging, closed forging, and isothermal forging.
I. Main Manufacturing Processes
**Open Forging:** Similar to traditional blacksmithing, the titanium alloy billet is heated and hammered into shape. It is low-cost but has lower precision, suitable for simple parts.
**Closed Forging:** Uses a die for extrusion forming. It saves material and has high precision, but the die is expensive, and the deformation speed must be strictly controlled.
**Isothermal Forging:** The die and billet deform slowly at the same temperature. It has low internal stress and high precision, used in demanding fields such as aerospace.
II. Key Process Parameters
- Temperature Control: Typically 900–950℃, requiring inert gas protection to prevent oxidation.
- Deformation Rate: For isothermal forging, the rate must be below 10⁻³ s⁻¹ to avoid grain coarsening.
- Lubrication: Use glass lubricant to reduce the coefficient of friction and minimize the risk of mold sticking.
III. Application Areas
- Aerospace: Manufacturing engine blades, fuselage structures, etc., requiring high specific strength and lightweight.
- Medical: Producing artificial bones and joints, requiring biocompatibility.
- Chemical: Manufacturing reaction vessels and heat exchangers, requiring corrosion resistance and high temperature resistance.
IV. Process Optimization Directions
- Automation: Adopting advanced equipment to improve efficiency and quality.
- Energy Saving and Environmental Protection: Optimizing heat treatment and forging processes to reduce energy consumption.
- Material Utilization: Rationally utilizing raw materials and reducing waste.
