Abstract
The utility model discloses a heating furnace for producing sponge titanium, which comprises a furnace body (1), wherein a resistance belt or a resistance wire (2) is fixed on the inner wall of the furnace body (1), and the resistance belt or the resistance wire 2 is wound on two rows of screw nail rods 4 in a zigzag way. The furnace body (1) comprises a metal shell (2) and an internal temperature presentation layer (3) formed by a high-temperature fiber module. Compared with a conventional heating furnace, the heating furnace is wholly bricked by the high-temperature fiber module, an electric heating body is fixed by a corrugated alloy belt and a ceramic screw nail, and the heating power can be counted according to a specific condition, so that the heating furnace has the advantages that the heating power is lower, the weight of the furnace body is lighter, the whole service life is longer, the temperature rise is faster when the heating furnace is used, the cooling is faster when the heating furnace is not used, the sealing property is better, the energy consumption of the unit yield is lower, and the like.
Description
Technical field
The utility model relates to a kind of process furnace, relates in particular to a kind of process furnace that magnesium reduction process is produced titanium sponge that is used for.
Background technology
The process that magnesium reduction process is produced titanium sponge is that magnesium and titanium tetrachloride are joined in the reactor, carries out reduction reaction, at high temperature carries out vacuum distilling then, finally obtains the product titanium sponge and sticks together.In the middle of the reduction distillation process, reactor is placed in the process furnace, in the middle of the reduction distillation process, open process furnace according to processing requirement in good time reactor is heated.Though process furnace has been a comparatively sophisticated equipment now, but produce from magnesium reduction process on the process characteristic of titanium sponge, to the requirement of process furnace and general process furnace by significantly different: not only require process furnace to have good heating properties, and require process furnace to have good radiating and cooling performance; Has certain sealing property.
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.
The utility model content
In view of this, the purpose of this utility model provides a kind of process furnace that magnesium reduction process is produced titanium sponge that is used for.
Above-mentioned purpose realizes by following proposal:
A kind of process furnace that is used to produce titanium sponge, it comprises body of heater, it is characterized in that, is fixed with resistive band or resistance wire on described inboard wall of furnace body.
According to above-mentioned process furnace, it is characterized in that described body of heater comprises metal shell and inner thermal insulating layer.
According to above-mentioned process furnace, it is characterized in that described inner thermal insulating layer is made up of the high temperature fiber module.
According to above-mentioned process furnace, it is characterized in that around the fixing many screw rod of described inner thermal insulating layer, an end of described screw rod inserts described inner thermal insulating layer on described inner thermal insulating layer, the other end stretches out described inner thermal insulating layer, and described resistive band or resistance wire solderless wrapped connection are on the extension of many screw rod.
According to above-mentioned process furnace, it is characterized in that described many screw rod are two rows, and arrange around described inner thermal insulating layer that described resistive band or resistance wire are arranged on the screw rod described two with the mode solderless wrapped connection of " it " font in staggered mode.
According to above-mentioned process furnace, it is characterized in that, between described resistive band or resistance wire and described inner thermal insulating layer, be provided with packing ring.
Process furnace of the present utility model is compared with the traditional heating stove, adopted the high temperature fiber module whole to build by laying bricks or stones, electric heating element adopts corrugated alloy band to add the porcelain screw retention, heating power can calculate as the case may be, and it is lower to have a heating power, and body of heater weight is lighter, whole service life is longer, advantages such as cooling is faster when heating up faster, blowing out during work, and sealing property is better, and the unit output energy consumption is lower.
