Description
Technical field
The present invention relates to technical field of production of sponge titanium, and in particular to reactor covers greatly chlorination in a kind of titanium sponge production
Magnesium tube passage processing method.
Background technique
During magnesium processes produce titanium sponge, after the reduction reaction of magnesium metal and titanium tetrachloride, steamed in reduction
It evaporates and also remains partial oxidation magnesium and metal magnesium addition in the titanium sponge in reactor.In order to this partial impurities from titanium sponge
Titanium sponge is separated and purified, the reduction distillation reactor for filling titanium sponge is docked with condensation reactor, is being evaporated in vacuo
Under state, the impurity such as magnesium chloride and magnesium metal are sent into condensation reactor by the big lid of carrying pipe in condensation reactor and are carried out
On the one hand condensation-crystallization obtains pure titanium sponge, the magnesium chloride and magnesium metal of condensation-crystallization on the other hand can be recycled.To prevent
Gaseous state magnesium chloride and magnesium metal block skirt after condensation-crystallization in big lid skirt, thus influence gaseous state magnesium chloride and magnesium metal with
The separation of titanium sponge, the prior art is to add the refractory insulating layer of electric heater and support electric heater in skirt periphery, with structure
At the big lid of heating.But the existing big lid of heating can only heat the catheter wall in big lid, it can not be by thermal energy Net long wave radiation
To conduit lower end, be easy gaseous state magnesium chloride and magnesium metal in big lid conduit lower end condensation-crystallization, once and crystal growth, it will
From bottom to top obstruction conduit and influence vacuum distillation separation, to reduce Sponge Titanium quality, extend manufacture cycle, increase life
Produce cost.Also, in magnesium method titanium sponge production process, after when turning distillation, reactor covers greatly magnesium chloride pipe extraction, connection
It is closed with blind plate at place.The channel reactor great Gai is all to be blocked dead in distillation process, has plenty of magnesium and blocks, have plenty of magnesium and
Magnesium chloride blocks.Dismantling processing mode is the closed blind plate in reactor big lid magnesium chloride pipe junction of dismantling, and is got through greatly with pneumatic pick
Cover magnesium chloride pipe channel；If magnesium blocks, disassembly work, which is at least handled 4 hours, can just clean out magnesium chloride pipe channel, sometimes
The same day can not clean out at all, need just clean up within second day by the processing such as immersion, delayed the big lid of reactor
Normal turnover, affects production.
Summary of the invention
The purpose of the present invention is to provide reactors in a kind of titanium sponge production to cover magnesium chloride pipe channel processing method greatly,
To solve the problems, such as that magnesium chloride pipe channel cleanup is time-consuming, laborious in the prior art, this method is easy to operate, alleviates disassembly work
Labor intensity, it is time saving, laborsaving.
To achieve the above object, the present invention adopts the following technical scheme:
Reactor covers greatly magnesium chloride pipe channel processing method, the method specifically: use silicon in a kind of titanium sponge production
Sour aluminium heat-preservation cotton makes a cylindrical body, is placed in reactor big lid magnesium chloride pipe channel, upper part of channel is sealed with blind plate
It closes.
Preferably, the diameter of the cylindrical body is slightly larger than or covers magnesium chloride pipe channel diameter greatly equal to reactor, due to
Alumina silicate heat-preservation cotton has certain flexibility, can deformation slightly, put it into reactor big lid magnesium chloride pipe channel, can
To increase the contact surface of cylindrical body Yu magnesium chloride pipe channel, prevent cylindrical body from falling off, the length of cylindrical body is less than or equal to reaction
Device covers greatly magnesium chloride pipe passage length.
Wherein, in order to save material, the alumina silicate heat-preservation cotton can choose remaining silicic acid when masonry reduction-retort
Aluminium keeps the temperature cotton material, and remaining material is just fully utilized when building reduction-retort in this way, avoids waste.
Wherein, currently preferred reduction-retort be I type furnace, in practical application, this method can also be used in it is U-shaped
On furnace.
During distillation, it is only capable of adhering to alumina silicate heat-preservation cotton cylinder body surface during magnesium vapor and magnesium chloride evaporation of vapours
Face has blocked magnesium steam and magnesium chloride steam to echo aggregation in channel interior suction.Therefore, when clearing up magnesium chloride pipe channel, as long as
Dismantle and close blind plate, alumina silicate heat-preservation cotton cylindrical body of dismantling, facilitate it is easy to operate, when preventing from getting through channel with pneumatic pick caused by
Channel deformation.
In the magnesium and more magnesium chloride of aggregation, directly alumina silicate heat-preservation cotton cylindrical body is dismantled with pneumatic pick, it is general time-consuming
Time that is convenient and efficient for 2~5min, effectively saving greatly alleviates the labor intensity of disassembly work, ensure that safe life
It produces.
The method of the present invention has the advantages that
1, the method thoroughly solves the problems, such as that magnesium chloride pipe channel cleanup is time-consuming, laborious.It is only needed using method of the invention
It dismantles and closes blind plate, channel surrounding is slightly handled with pneumatic pick, the simple cylindrical body of alumina silicate heat-preservation cotton can fall off, the working time
It is short, it can be settled within 5 minutes.
2, the method greatly alleviates the labor intensity of disassembly work, ensure that safety in production.
3, prevented the big lid magnesium chloride pipe channel deformation of the reactor as caused by when pneumatic pick hammer drill is channel cleanup, it can
The effective service life for extending the big lid of reactor, save the cost.
