Description
Technical field
The utility model relates to a kind of sponge titanium smelting technology, particularly a kind of heating furnace that is used for titanium sponge production.
Background technology
Industrialized now titanium sponge production is mainly the method for magnesium-reduced titanium tetrachloride under the high temperature, and the heating furnace that the method is produced the titanium sponge use is generally well formula resistance furnace.Such stove outermost layer is the steel construction furnace shell, lay heat-insulating property alumina silicate fibre preferably in the furnace shell, be right after the alumina silicate fibre layer and build light heat-insulating fire resistant brick by laying bricks or stones, place high temperature resistant on the light heat-insulating fire resistant brick and the intensity support brick of corundum matter preferably, on the support brick, place resistance wire.The production process of titanium sponge is divided reduction and is distilled two stages, the reduction phase reaction is exothermic reaction, need to consider the heat radiation of heating furnace internal reaction device, the distillation stage requires heating furnace that heat insulation effect preferably will be arranged, should to keep vacuum state in the stage heating furnace simultaneously, in order to satisfy technologic heat radiation and vacuum requirement, heating furnace is provided with inlet and outlet, vacuumizes interfaces such as adapter and thermometric adapter.For example: the Chinese patent of publication number CN1963361A, open day is on May 16th, 2007, a kind of heating furnace of produce titanium sponge by combination method is disclosed, this heating furnace belongs to pit furnace, this class A furnace A mainly has the following disadvantages in the titanium sponge production process: heating furnace furnace lining light heat-insulating fire resistant brick own wt is born by lower floor's furnace lining, generally the reinforcement bracing or strutting arrangement can't be set, add that standing long-term heavily burning shrinks, furnace lining sinks serious, directly causes the damage of temperature element and heating element heater; Put the support brick of putting resistance wire because its special construction stops the iron scale that comes off from reactor easily, thereby makes the heating well damage; Because the furnace lining quality is bigger, the stove amount of stored heat is big, and stove intensification and temperature fall time are longer, have not only increased the energy consumption of product, and have influenced the production capacity of heating furnace, can not give full play of the production advantage of this class A furnace A.
The utility model content
Technical problem to be solved in the utility model provides a kind of heating furnace that titanium sponge is produced that is used for, and solves heating furnace because of technical problems such as the long-term energy consumption of using maintenance cost height that back furnace lining sinking damages heating and temperature element, heating furnace, product are big.
For the purpose that realizes solving the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of heating furnace that titanium sponge is produced that is used for of the present utility model, comprise the steel construction furnace shell, furnace lining material, heating element heater, air inlet, air outlet, vacuumize and take over and the thermometric adapter, be characterised in that: weld anchor firmware on steel construction furnace shell inwall, steel construction furnace shell inwall is equipped with one deck heat-barrier material asbestos board as furnace lining material shop layer, anchoring piece on the furnace shell inwall is connected and fixed the ceramic fibre module of compression moulding in advance as furnace lining material, the ceramic fibre module contains built-in anchoring piece, built-in anchoring piece is connected and fixed with the anchoring piece that is welded on the furnace shell inwall, and furnace bottom adopts refractory brick to build by laying bricks or stones.
A kind of heating furnace that titanium sponge is produced that is used for of the present utility model, further optimized technical scheme can be: described air outlet is 5, and air outlet is on same horizontal plane; Air inlet lays respectively on two horizontal planes, 4 air inlets on each horizontal plane.
A kind of heating furnace that titanium sponge is produced that is used for of the present utility model, further optimized technical scheme can also be: described heating element heater is a corrugated resistance, corrugated resistance hangs with the pottery nail and is fixed on the ceramic fibre module.Technique scheme further optimized technical scheme is: the resistance wire of described corrugated resistance is provided with refractory material to be stopped.Can prevent the iron scale overlap joint like this, avoid causing two resistance wire short circuits.
Heating furnace of the present utility model, this type of furnace furnace lining material adopts thermal conductivity factor lower, ceramic fibre module that density is littler, thermal capacitance is less replaces light heat-insulating fire resistant brick, and ceramic fibre module major advantage is that thermal conductivity factor is 1/4 of a traditional light heat-insulating fire resistant brick; Density is about 1/5 of traditional light heat-insulating fire resistant brick that adopts; Thereby avoided furnace lining material to sink, and then damaged the problem of heating element heater and temperature element because of the gravity load that bears the top furnace lining and long-term heat shrink; Furnace bottom adopts refractory brick to build by laying bricks or stones, can strengthen the intensity of furnace bottom, prevents that iron scale that production process comes off from reactor etc. from damaging furnace bottom; The design of air inlet, air outlet makes the free convection that can lean on air between the inlet and outlet in titanium sponge production reduction process dispel the heat to the conversion zone of heating furnace internal reaction device; When entering still-process, inlet and outlet all seals, and by vacuumizing adapter the heating furnace burner hearth is vacuumized to satisfy technological requirement.
By adopting technique scheme, the utlity model has following beneficial effect:
Heating furnace of the present utility model, its furnace lining material and heating material usage reduce significantly; Empty stove heats up and temperature fall time shortens, and is about 1/3 of traditional heating stove, has shortened the time between overhauls(TBO) of stove greatly; Because adopted the furnace lining material of low thermal conductivity, the heating furnace heat-insulating property significantly improves, the furnace shell outside wall temperature obviously reduces, and energy-saving effect is obvious, and energy consumption of unit product descends about 20%.
Description of drawings
Fig. 1 is a kind of heating furnace overall structure figure that titanium sponge is produced that is used for of the present utility model.
Fig. 2 is a kind of heating-furnace lining structure detail drawing that titanium sponge is produced that is used for of the present utility model.
Among the figure, 1 is titanium sponge production reactor; 2 is air outlet; 3 is air inlet; 4 for vacuumizing adapter; 5 is furnace bottom; 6 is the steel construction furnace shell; 7 are stove layer material shop layer; 8 is anchoring piece; 9 is the ceramic fibre module; 10 is the heater element resistance band; 11 is the pottery nail.Wherein, anchoring piece divides two parts, a part and furnace shell welding, and another part is in advance in the ceramic fibre module.Totally 5 of air outlets are all on same horizontal plane; Totally 8 of air inlets, two-layer about dividing, 4 every layer.
