The heated sponge titanium oxide is reduced to pure metal by reacting with it. The reducing medium undergoes an oxidation-reduction reaction with the metal oxide at high temperature, releasing oxygen, which is discharged by opening the valve of the air outlet pipe. The reduction reaction then converts the metal oxide into metal vapor. At the same time, the motor is controlled by the single-chip microcomputer to rotate the baffle on the outer surface of the connecting rod to a vertical position. The metal vapor flows in the furnace body together with the reducing medium until the metal vapor enters the cooling area at the top of the furnace body.
