Abstract
The unitedly produced titanium sponge electric heater is well type electric heater with the heater is made of a housing, a brasque and an electric heating device. The brasque is composed of firebrick, heat reserving layer and heat insulating layer, with the electric heater a resistance wire loaded on the wire resting brick, featuring in the heat insulating layer made of rock wool board (5), heat reserving layer of bulking vermiculite, having at least 8 wind inlets (1) evenly set at the center of the hearth of the heater. At least four wind outlets (2) are envenly arranged on the top of the furnace wall, with exhausting openings (3) set on the furnace wall, drawing air from the exhausting opening (3) to keep low vacuum inside the hearth, keeping the reactor (9) not being flat. It has strong radiating ability, improved reacting speed, and fine heat reserving performance, obvious in energy saving with outer wall temperature more than 10DEG C less than existing electric heaters, with a ton of titanium saving energy more than 500Kwh.
Description
Technical field
The present invention relates to titanium sponge production, produce the process furnace of titanium sponge in particular to the magnesium method.
Background technology
The process of produce titanium sponge by combination method is that titanium tetrachloride is added reactor, makes titanium sponge with magnesium metal reduction and distillation.Electric pit-type heating furnace is the necessary equipment of reduction distillation operation.Reactor places and carries out the reduction distillation operation in the electric pit-type heating furnace, electric pit-type heating furnace is a kind of sophisticated equipment, but because the characteristics of titanium sponge technology itself are produced in integrated process magnesium reduction vacuum distilling, electric pit-type heating furnace is required have significantly different with general electric pit-type heating furnace: not only require to have certain heating function, and because titanium tetrachloride and magnesiothermic reduction reaction are strong exothermic reaction, a large amount of reaction heat needs to discharge, so reduction phase requires electric pit-type heating furnace to have good heat-sinking capability at the reduction reaction band; The distillation stage is because operation under the high vacuum in high temperature and reactor; furnace shell must seal and be furnished with evacuator device; it is indeformable with guard reactor to keep being low vacuum state in the burner hearth aborning; therefore require process furnace to have better seal performance and good heat-insulating property, reach the purpose that reduces power consumption and keep burner hearth vacuum tightness.
Titanium industrial expansion direction is the maximization of single furnace output, heat-sinking capability, sealing property and heat-insulating property to electric pit-type heating furnace have all proposed high request, and the electric pit-type heating furnace of prior art has not satisfied large-scale reduction distillation integrated process and produced the requirement of titanium sponge technology to electrical heater.
Summary of the invention
Order of the present invention provides a kind of electrical heater of reduction distillation produce titanium sponge by combination method, not only has certain heating function, and has good heat-sinking capability at reduction phase at the reduction reaction band; Have better seal performance and heat-insulating property in the distillation stage, to be used for produce titanium sponge by combination method.
In order to achieve the above object, the process furnace that technical program of the present invention lies in produce titanium sponge by combination method is an electric pit-type heating furnace, electric pit-type heating furnace has furnace bottom and furnace wall, the furnace wall is followed successively by furnace shell from outside to inside, furnace lining and electric heating element, furnace lining is by refractory brick, thermal insulation layer, thermal insulation layer is formed, electric heating element is that resistance wire is installed in and puts on the brick, technical scheme electrical heater of the present invention is characterised in that the thermal insulation layer of furnace lining is a rock cotton board, thermal insulation layer is an expanded vermiculite, and be provided with at least 8 blast inlets in that process furnace furnace wall middle part (reaction zone zone) is uniform, top, process furnace furnace wall is uniform to be provided with at least 4 exhaust outlets, a segment length vertically upward after coming out of the stove, exhaust outlet is arranged, to increase the draft of exhaust outlet to the hot gas exhausting, also be provided with the mouth of finding time on the process furnace furnace wall, be used for burner hearth is taken out rough vacuum.The electrical heater of technical scheme of the present invention is strong in the heat-sinking capability of reduction phase, and the heat-insulating property and the sealing property in distillation stage are strong; When produce using in the reduction phase burner hearth speed of air flowing can satisfy the heat radiation needs of reduction process; can improve the speed of response of reduction process; after reduction finishes; blast inlet, exhaust outlet are stopped up; start evacuator device and found time to guarantee vacuum tightness in the burner hearth in distillation stage; guard reactor is indeformable, and the vacuum in the burner hearth also helps the electrical heater insulation.
It is strong that the electrical heater of technical scheme of the present invention has heat-sinking capability, increased the speed of response of reduction process, has good heat-insulating property, and outside wall temperature is lower than the electrical heater of prior art, energy-conservation obvious, reduced the power consumption of still-process.

Embodiment
Embodiment
In certain titanium sponge factory, adopt magnesium reduction distillation produce titanium sponge by combination method.As accompanying drawing 1, shown in Figure 2, electric pit-type heating furnace has furnace bottom and furnace wall, electric pit-type heating furnace is uniform at process furnace furnace wall middle part to be provided with 12 blast inlets 1, top, process furnace furnace wall is uniform to be provided with 6 exhaust outlets 2, a segment length is vertically upward arranged after exhaust outlet 2 is come out of the stove, also be provided with the mouth 3 of finding time on the process furnace furnace wall; As shown in Figure 3, the electric pit-type heating furnace furnace wall is followed successively by furnace shell 4, furnace lining and electric heating element from outside to inside, and furnace lining is made up of refractory brick 7, thermal insulation layer, thermal insulation layer, and electric heating element is that resistance wire is installed in and puts on the brick 8, the thermal insulation layer of furnace lining is a rock cotton board 5, and thermal insulation layer is an expanded vermiculite 6.During reduction, the reduction reaction of magnesium and titanium tetrachloride is carried out in reactor 9, heat of reaction is delivered to reactor 9 walls by melt, open blast inlet 1 and exhaust outlet 2 this moment, freezing air enters in the burner hearth from blast inlet 1, is heated with reactor 9 wall generation heat exchanges, because density diminishes, air rises, the pyritous air is discharged burner hearth from exhaust outlet 2, thus the purpose that reaction heat is distributed in realization; Enter distillation during the stage; because the body of heater overwhelming majority has had heat-insulating property preferably; only need blast inlet 1 and air outlet 2 are incubated and seal; can satisfy the heat-insulating property and the sealing property in distillation stage; the furnace outer wall temperature is lower than the electrical heater of prior art more than 10 ℃; start evacuator device simultaneously and find time, finding time to make by the mouth 3 of finding time has rough vacuum in the burner hearth, and guard reactor 9 is constant flat.
Application shows that the present invention has satisfied the requirement of magnesium reduction distillation produce titanium sponge by combination method to the reduction distillation electrical heater preferably, and reduction can be carried out with bigger speed, more than the titanium saving energy 500kwh.
