Description
Technical field
The invention belongs to titanium sponge production field, particularly a kind of titanium sponge reduction distillation reaction unit and production technique.
Background technology
Through the development of 60 years, titanium sponge production technique was tending towards unified gradually: Kroll process (magnesium processes) and reduction---and distillation combination producing, equipment, production capacity are towards large scale development.
Titanium sponge reduction distillation operation, being the important step of being produced titanium sponge by titanium tetrachloride, is the quality of titanium sponge, the key of cost control.In reaction unit, disposablely add magnesium, then in reduction process, continuously add titanium tetrachloride, titanium tetrachloride after liquid magnesium and gasification react at liquid magnesium surface, the titanium of produce liquid magnesium chloride (to sink to bottom reaction unit and to be interrupted discharge) and solid-state spongy (being rich in kapillary).After reduction terminates, under vacuum and the condition of high temperature, by magnesium remaining in reaction unit and magnesium chloride, be distilled in condenser, realize the purification to titanium sponge.Titanium sponge will realize application, the fragmentation that titanium must be sticked together, is pressed into electrode, vacuum arc furnace melting ingot casting, makes section bar.
Titanium sponge reduction reaction is thermopositive reaction, and reaction heat by the mode of convection current, mass transfer, must transmit from inside to outside, and distance reaction unit wall is far away, and dispel the heat more difficult, temperature is higher.
Current titanium sponge reduction is produced and is all adopted point type to feed in raw material, and is namely fed in raw material in one or several some position by filling tube.Titanium tetrachloride concentration, reduction reaction severe degree, reaction heat, all in normal distribution, namely more close to feed point position vertical line position, its value is larger.
Traditional sponge titanium is the reaction unit that uses of original production also, and be all drum type brake, feed point position is in cylinder center position, therefore reaction unit central position reaction heat is the most concentrated, and temperature is the highest, titanium sponge may be caused to sinter and fine and close.
Some mechanisms carried out the exploration of feeding raw materials from more than one places, but limit by drum type brake reaction unit, feed point position can only be symmetrical around cylinder center's line, although the reaction heat of position of center line can be reduced like this, but can't resolve the heat radiation of position of center line, therefore feeding raw materials from more than one places DeGrain, increases equipment making and manual operation difficulty on the contrary.
The at present technology all relatively opening of the operation such as chlorination, refining, electrolysis of titanium sponge production in the world, reduction distillation technology all takes the policy of bottling up only, and domestic also do not have technology introduction precedent.
The aspect such as titanium sponge quality, comprehensive cost of China, does not all locate inferior position in the world, but reduction distillation unit product power consumption, titanium sponge workability (compactness extent is evenly then easy to processing) are obvious with advanced international standard gap.Domestic simple equipment, the production capacity all selected maximizes at present, and namely augmenting response assembly dia and height, reduce unit product power consumption; And this equipment enlarging will make, and product radiating condition is deteriorated, titanium sticks together highly increases, single stove product accounts for stove overlong time, titanium is caused to stick together central part and bottom densification, workability deteriorates.
