The invention discloses a smelting method and equipment for directly smelting metal titanium from titanium dioxide,and belongs to the field of metal smelting. The smelting method comprises the steps that the titanium dioxide is prepared; microwave irradiation is carried out on the prepared titanium dioxide; oxygen atoms of the titanium dioxide are replaced by nitrogen plasma to separate out the metal titanium. The smelting equipment comprises a reaction furnace and a feeding pipe,an exhaust pipe,a microwave generator and a nitrogen plasma torch generator which are arranged on the reaction furnace. According to the smelting method and equipment for directly smelting the metal titanium from the titanium dioxide,extremely-short-wavelength microwave makes titanium atoms and oxygen atoms in thetitanium dioxide vibrate strongly,so that titanium-oxygen bonds are weakened,then nitrogen plasma torch emission is utilized,nitrogen ions have a strong oxidizing property,oxygen is taken from the titanium dioxide to form nitrogen dioxide,and the titanium is separated out. The smelting method and equipment for directly smelting the metal titanium from the titanium dioxide can directly smelt the metal titanium from the titanium dioxide,the titanium smelting processes are greatly simplified,the cost is reduced,and the titanium yield and quality can be commercially improved.
