Titanium blank production process
Raw Material Preparation: The first step in the production process is the selection and preparation of raw materials. Titanium ore, commonly known as titanium dioxide, is primarily used as the main source of titanium metal. The ore is purified and processed to remove impurities and obtain a high-purity titanium dioxide powder.
Chlorination: The purified titanium dioxide powder is then mixed with coke and chlorinated at high temperatures, typically around 900-1000°C. This process, known as the chloride process, converts the titanium dioxide into titanium tetrachloride (TiCl4).
Reduction: The titanium tetrachloride is then reacted with a reducing agent, such as magnesium, in a closed furnace at temperatures above 1000°C. This reaction results in the reduction of the titanium tetrachloride to metallic titanium.
Casting: The molten titanium is cast into ingots or other desired shapes using various casting techniques, such as vacuum arc remelting or electron beam melting. This step helps to solidify the titanium and form a base for further processing.
Hot Working: The solidified titanium ingots or shapes are then subjected to hot working processes, such as hot rolling, hot forging, or hot extrusion. These processes involve heating the titanium at high temperatures and shaping it into desired forms, such as sheets, plates, bars, or tubes, through mechanical deformation.
Cold Working: The hot worked titanium is further processed through cold working techniques, such as cold rolling, cold forging, or cold extrusion. These processes involve shaping the titanium at room temperature to achieve the desired dimensions and improve the mechanical properties, such as strength and toughness.
Heat Treatment: The cold worked titanium may undergo heat treatment processes, such as annealing or aging, to relieve internal stresses and enhance the material's properties. Annealing involves heating the titanium at specific temperatures and then slowly cooling it, while aging involves subjecting the titanium to specific temperatures for extended periods to promote precipitation hardening.
Finishing: The final step involves various finishing operations, such as machining, polishing, or surface treatment, to achieve the required surface finish, dimensional accuracy, and aesthetic appearance of the titanium blanks.
