金属钛具有比重小、强度大、耐高温、耐腐蚀等优点,因此,钛被广泛应用于飞机、火箭、导弹、宇宙飞船、深水潜艇、化工、石油等工业部门。目前国内外生产钛工艺仍然是传统的克罗尔法(镁还原法)和享特法(销还原法)。以镁还原工艺为例,即在还原炉中用金属镁还原四氯化钛生产金属钛,而镁则转换成氯化镁,氯化镁再经过熔盐电解生产金属镁返回还原炉循环使用。熔盐电解法生产金属钛新工艺是以四氯化钛为原料熔盐电解生产金属钛。新工艺即省掉了还原工序,又不需要金属还原剂,是较理想的炼钛工艺之一。
Titanium is widely used in aircraft, rockets, missiles, spacecraft, deep-water submarines, chemical industry, oil and other industrial sectors due to its small specific gravity, high strength, high temperature resistance and corrosion resistance. The current domestic and international production of titanium is still the traditional method of Kroll (magnesium reduction method) and enjoy the special law (sales reduction method). To magnesium reduction process, for example, in the reduction furnace with magnesium metal reduction of titanium tetrachloride production of titanium metal, magnesium is converted to magnesium chloride, magnesium chloride and then through molten salt electrolysis production of magnesium return to the reduction furnace recycling. Molten salt electrolysis production of titanium metal is the new process of titanium tetrachloride electrolysis of molten salt electrolysis metal titanium. The new process that eliminates the reduction process, but also does not require metal reductant, titanium is one of the more ideal technology.
