Background technology
Magnesium reduction is a unique method of producing titanium sponge at present in enormous quantities.The main points of this method are: MAGNESIUM METAL is added in the airtight metal vessel, be warmed up to more than the fusing point of magnesium, add titanium tetrachloride then continuously, make it to react with MAGNESIUM METAL, strictly control the adding speed of titanium tetrachloride in the reduction process and conversion zone is carried out ventilation and heat, the temperature maintenance that makes conversion zone guarantees carrying out smoothly of reduction reaction in certain scope.Also to regularly emit by-product magnesium chloride in the reduction process.After reduction finishes, reduzate is sent to vacuum distilling or after cooling, take out and be crushed to certain particle from container and carry out wet processing, obtain purified titanium sponge to remove magnesium chloride residual in the titanium sponge and superfluous MAGNESIUM METAL.Reduction distillation technology has conclusive effect to the quality of titanium sponge product, is the critical process that magnesium reduction one vacuum distillation method is produced titanium sponge, and the titanium sponge production technology of country or enterprise is mainly reflected on the reduction distillation technology.
The structure of existing Reaktionsofen comprises body of heater and inner process furnace resistance wire, and body of heater is the refractory brick body of heater, and it is bigger recept the caloric, has heating starting and the blowing out required problem that time is long, adiabatic heat insulating effect is relatively poor of lowering the temperature; In addition, existing process furnace resistance wire is a canoe, is placed on corundum and puts on the brick, and the oxide skin because titanium sponge reactor oxidation meeting comes off drops on the resistance wire, can cause resistance wire damage frequency height, work-ing life to lack.Simultaneously, because refractory brick self heat absorption is bigger, so heating power is also big, the more high many outstanding problems of energy consumption.
Summary of the invention
Purpose of the present invention will be eliminated above-mentioned the deficiencies in the prior art and shortcoming exactly, provide that a kind of body of heater quality is lighter, thermal power consume little, convenient use a kind of be used for magnesium reduction--vacuum distillation method produces the process furnace of titanium sponge.
For achieving the above object, the invention provides a kind of process furnace that magnesium reduction-vacuum distillation method is produced titanium sponge that is used for, comprise body of heater and heating unit, body of heater comprises metal furnace shell, thermal insulating layer and folding module, the thermal insulating layer is arranged at metal furnace shell inwall, and folding module is arranged at thermal insulating layer inwall; Heating unit comprises fixing part and heater block, and fixing part is fixedly set in folding module inwall, and heater block is arranged on the fixing part, and described heating unit is provided with two at least, and heating unit can be operated separately.
Preferably, the fixing part of described heating unit is the double-deck screw ring texture that is crisscross arranged, and the heater block of heating unit is resistive band or resistance wire, is wavy winding and is arranged on the double-deck screw ring texture.
Preferably, the fixing part of described heating unit is an insulating material.
Preferably, be provided with packing ring between the heater block of described heating unit and the folding module.
Preferably, described thermal insulating layer is made up of the high aluminum fiber blanket, and described folding module is the folding module of high alumina temperature fiber.
Preferably, described process furnace also comprises block, is arranged at each heating unit top, and block is made of the heat-resistant light insulating material of hollow.
Preferably, described process furnace also comprises the reactor guidepost, is fixedly set in body of heater metal shell inwall fire door place, and reactor guidepost length is greater than the thickness of thermal insulating layer thickness and heating unit, and guidepost is made up of heat-resistance stainless steel.
Beneficial effect of the present invention:
1, heating unit top is provided with that block can effectively solve and damages the problem of heating unit because the oxidized metal cortex drops on heating unit.
2, heating unit can be adjusted quantity according to the selection of the size of body of heater and power, and cooling is faster when heating up faster, blowing out during work.
Advantages such as it is lighter that the refractory brick body of heater that 3, the structure of body of heater of the present invention is traditional relatively has body of heater weight, and whole service life is longer, and sealing property is better, and the unit output energy consumption is lower.
