Titanium Foil

The raw material for industrially producing titanium is mainly rutile ore or high titanium slag (containing 92% or more of Ti02). Titanium sponge production process is based on high titanium slag and petroleum coke as raw material for the production of titanium tetrachloride. Titanium sponge can be obtained by reducing refined titanium tetrachloride with magnesium or sodium in a rare gas stream.
Magnesium reduction distillation method: the proportion of high titanium slag and petroleum coke is 100 (30~33), and the mixture is broken to less than 160 mesh, and sent to the fluidized bed chlorination furnace, and the chlorine gas is passed through the bottom of the furnace, uniformly enter the reaction section of the furnace body, and react with the mixed material of high titanium slag and petroleum coke. The reaction temperature was about 850 °c. The generated titanium tetrachloride gas is discharged from the top of the furnace and enters two separator dust collectors connected in series, so that high boiling points such as iron trichloride, iron dichloride, manganese dichloride and aluminum trichloride mixed in the titanium tetrachloride gas are deposited at the bottom of the separator dust collector. The gas was reintroduced into the two sets of condensers connected in series, and the titanium tetrachloride gas was cooled to below 136 ° C. To obtain a crude titanium tetrachloride solution. The low-boiling matters, such as silicon tetrachloride, therein are distilled off by means of a float valve column distillation. After heating to 140 ° C. In a copper chip Tower, the gasified titanium tetrachloride is passed into a copper chip Tower, and the contained impurity vanadyl trichloride is reduced by copper to a low-valent chloride of vanadium. The purified titanium tetrachloride gas discharged from the top of the column was subjected to a reduction reaction with magnesium in a rare gas stream at about 900 ° C. To obtain titanium sponge. Since the resulting sponge-like titanium also contains magnesium chloride as a by-product and unreacted magnesium, the sponge-like titanium must be placed under a vacuum of 0.1 to 10-3 Pa, the impurities were separated from the titanium by heating to about 1000 °c.

titanium alloy has high strength, a large number of structural materials used in the manufacture of military supersonic aircraft, compression Components of jet engines, components of aircraft frames, housings, fire barriers, rivets, structural components of air transport equipment, there is a “space metal”; Military facilities and military ships armored plate and propeller blades. In the civilian industry, titanium and its alloys can be used in the manufacture of various pumps, valves, filtration, evaporation equipment wire mesh and various machine parts. Powdered titanium can be used as an oxygen scavenger in the electron tube manufacturing process.
