Titanium raw materials mainly used to produce titanium dioxide, titanium metal (titanium sponge), titanium steel, and the electrode coating. The proportion of them is slightly different between China and abroad. Titanium white, China accounted for 88%, foreign accounted for 92.4%; metal titanium (sponge titanium), China accounted for 10%, foreign accounted for 5.3%; titanium-containing steel and electrode coatings, China accounted for 2.0%, foreign accounted for 2.3%.
Titanium dioxide is not only a white pigment with excellent performance, but also an important chemical raw material. It is widely used in the coatings, inks, plastics, rubber, paper and chemical fiber industries. Titanium white paint, bright colors, pure color; titanium white is the advanced filler of paper, making the paper thin and opaque, high whiteness, good gloss, strong strength and smooth and easy to use. Titanium dioxide is used in the plastics industry as an opaque colorant; it is used in the rubber industry to give white and light-colored rubbers high strength, high elongation, ageing resistance and fading resistance. It is also the best matting material for chemical fibers, giving transparent chemical fibers a permanent matting effect and improving toughness. In addition, it is also used in enamel, electrical appliances, electronic materials and so on.
After the titanium concentrate is smelted into sponge titanium, the ingot is ingot and made into industrial pure titanium and titanium alloy titanium. Titanium and titanium alloy titanium are mainly used in the aerospace and aerospace sectors. Compared to alloy steels, titanium alloys can reduce aircraft weight by 40%. Others such as satellite casings, spacecraft skins, rocket engine casings, missiles, etc., can be used in titanium alloys. The use of industrial pure titanium and titanium alloys in non-aerospace sectors is mainly in power station condensers, seawater contact installations, chemical installations and some mechanical engineering. In particular, titanium for seawater desalination heaters is an epoch-making event in the development of titanium industry. The military division mainly uses titanium for ship and weapon production.
In addition to titanium metal used in the production of industrial pure titanium and titanium alloys, the further use in the production of titanium and titanium-containing iron alloy steel steel industry. Titanium is used as an additive element in steel to change the properties of steel. The steel is tempered to a higher temperature at the same tempering temperature with higher strength and hardness, or the same hardness requirement. At present, China's titanium-containing steels have high-strength low-alloy steels, structural steels, stainless steels, heat-resistant alloys, ultra-high-strength steels and magnetic steels. They are widely used in automobiles, ships and oil drilling, and have developed into only manganese based steel is inferior to the second largest steel.
The main titanium-containing mineral rutile is also an indispensable raw material for high-quality electrode coating.
The following table lists the technical and economic indicators required for ilmenite and rutile for the above different uses.
According to the characteristics of molding, injection mold and thermoplastic plastic mold are divided into two types. According to the molding process, it can be divided into transfer mold, blow mold, casting mold, hot molding mold, hot pressing mold (compression mold), injection mold, etc. Among them, the hot pressing mold can be divided into three types, i.e., overflow, semi-overflow and non-overflow, and the injection mold can be divided into two types, i.e., cold runner mold and hot runner mold. It can be divided into two types: mobile type and fixed type.
