Description
Technical field
The utility model belongs to the Metal smelting technical field, particularly the smelting of rare metal titanium.
Background technology
The reactive mode of MAGNESIUM METAL reducing metal titanium from titanium tetrachloride is adopted in the smelting of titanium sponge.The series connection stove is all adopted in the smelting of titanium sponge at present, and promptly retort is connected with cooling tank and is one.Because of series connection stove quality of production instability, consumes energy is big, and is big for environment pollution, and workman's manipulation strength is big, and workload is big, therefore, presses for the higher and energy-conservation Reaktionsofen of a kind of efficient in sponge titanium smelting.
Summary of the invention
The utility model purpose provides a kind of sponge titanium reaction furnace, has solved the drawback in the existing sponge titanium smelting process.
Specifically, sponge titanium reaction furnace comprises retort and cooling tank; Retort inwall external fixation has nichrome wire, and nichrome wire is connected with current conducting rod, and retort is wrapped up with thermal insulation layer and furnace wall, and retort top is communicated with evacuation tube; Cooling tank has a watercooling jacket, its top is communicated with the cooling tank evacuation tube, retort and cooling tank are arranged side by side and are communicated with pipe core between the two with the big lid on both sides is fixing respectively, are wrapped with the internal heating cover at pipe core, are communicated with delivery pipe on cooling tank top.
Control valve is installed in evacuation tube, and this control valve comprises valve body, threshold switch and valve linker, and threshold switch is contained in the valve body, and linker is connected with the valve body external fixation.Evacuation tube is connected with vacuum system, is used for taking out the unnecessary gas of retort (as air, MgCl2).
Have blast inlet and air outlet on the retort sidewall, blast inlet is positioned at the retort middle part, and air outlet is positioned at retort top.
A plurality of temperature tubes are housed on the retort sidewall, and this temperature tube is electrically connected with the retort Controlling System.Be used for measuring control stove silk temperature.
In the retort inner wall surface titanium layer of oozing is arranged.
Well heater is the metal strip that nichrome is made in the internal heating cover of pipe core external parcel.Because pipe core is used for ligation jar and cooling tank, MgCl2 gas enters cooling tank by this pipe, for preventing MgCl2 condensation of gas caking, at pipe core external parcel internal heating cover, the metal strip that the utility model adopts nichrome to make is more energy-conservation than nichrome wire, and efficient is higher.
Be connected with the chilled water control tube in the cooling tank side.
The utility model advantage is to have changed series connection stove quality of production instability, and consumes energy is big, and is big for environment pollution, and workman's manipulation strength is big, the problem that workload is big.The utility model Reaktionsofen changes into has the advantages that with the internal heating pipe coupling energy-conservation, safety, reaction times are lacked in the middle of parallel.Such as, originally 1 ton of series connection stove of Shi Yonging is wanted about about the 8000 yuan/stove of power consumption, and 3 tons and the combination oven of the present utility model that use utilize titanium tetrachloride and reactive magnesium heat release generate energy in reinforced process, reinforced control balance, make stable temperature control, power consumption is approximately about 6000/stove, and waste gas also reduced 20%～30%, reduces the pollution to air.Previously used reactor all uses after overpickling, and present only simply polishing, scouring just can be oozed titanium and be used.Blast inlet to process furnace carries out appropriate design, thereby has played good heat insulation effect, and the inside and outside point for measuring temperature of process furnace is controlled accurately, makes the thermotonus sensitivity, can accurately judge the end distillation time.Bed thickness in the previously used big lid, plugging easily, big now lid attenuate side, the internal layer better heat preservation reduces by 90% not plugging, cross channel heater and be adapted as the nickel chromium triangle band, 220 electric currents being fallen shorten 2 and a half hours 80 heat-up times (increases a control valve with 4 hours pipelines of finding time originally, a large amount of gas magnesium dichlorides is accurately controlled in person who lives in exile's cooling tank, guarantee security of system, can ensure the unimpeded of passageway system again, reduce workman's labor capacity.
The titanium sponge that utilizes the utility model to smelt, through reaching more than 95% by detecting qualification rate, quality product all reaches I, more than the II level product, and the titanium plate that shuts out does not have snow.
