Description
Technical field
The present invention relates to a kind of non-ferrous metal metallurgy technology, particularly a kind of anti-blocking tube heating device that is used for titanium sponge production.
Background technology
Titanium sponge is the primary raw material in the titanium alloy melting, and the main method of present industrial production titanium sponge is the Kroll method, and the ultimate principle of this method is at first to utilize Mg and TiCl
4Reduction reaction generate Ti, remove excessive Mg, reaction product MgCl by high-temperature vacuum distillation then
2With a spot of titanium chloride, obtain spongiform titanium at last and stick together.
Inverted U associating stove is the main type of furnace that present titanium sponge is produced, its basic structure is contained titanium reactor and condenser for adopting the inverted U pipe connecting to connect, the inverted U pipe connecting installed channel heater additional, when having served as channel heater and being elevated to more than 800 ℃, vacuumize from condenser, make magnesium chloride etc. in the middle of inverted U is taken over, pass through, on condenser wall, cool off then.But in the production process, the vertical tube part that the inverted U pipe connecting is connected with condenser is stopped up easily, operator have to regularly open inspection and mediation, this continuity that not only influences still-process has also prolonged distillation time, has increased meaningless power consumption, if deal with improperly, also can increase the probability that the titanium sponge air inlet is polluted in the mediation process, thereby influence quality product.
Domestic titanium sponge manufacturer generally covers at cold junction reaction condenser and installs internal heater additional, and inverted U pipe connecting vertical tube partly stops up when preventing to distill.
For example: denomination of invention discloses a kind of internal heater of this type for " producing distillation pipeline and heating unit thereof on the reactor cap of titanium sponge ", publication number are the Chinese patent of CN2830416Y.Its making method is: in inverted U pipe connecting and condenser junction, build up flame retardant coating with refractory brick or aluminosilicate fiber cotton, install resistance wire then additional and heat on flame retardant coating.The weak point that exists in this device use is that internal heater is positioned at the big lid of condenser inside, and space of living in is narrow and small, during heat temperature raising, because the resistance wire self-temperature is very high, add that the resistance wire major part is embedded in the flame retardant coating, cause the thermal shocking of stove silk bigger, be easy to generate heat lodging phenomenon.Carbon steel iron scale around the well heater comes off easily in addition and easy to clean not, in case iron sheet is overlapped on the stove silk, makes the stove silk in use produce fusion and short circuit phenomenon, has to sever shrouding, changes internal heater, makes that use cost and maintenance cost are high.
The Chinese patent of publication number CN101245412A, introduced a kind of internally heating apparatus and preparation method thereof, this patent is by utilizing the bonded internal heater of suspension type resistive band and bottom electrical stopband, well heater with the CN2830416Y patent on the principle is identical, use can not well solve the plugging problem in the titanium sponge production distillation stage, and use is because the insufficient strength of refractory fiber cotton and bottom thermal radiation dish, in big lid upset scale removal process, resistive band and internal heater mold cavity are easy to generate displacement and bump, cause damage in various degree, cause this heating unit shorter work-ing life, sometimes use to be no more than once and just scrap, and be not easy to keep in repair and recycle.
