Embodiment
In Fig. 1,2; The titanium alloy heat treatment furnace of the resistive heating of the utility model is used for conventional Forge Heating, the high temperature forging heating of titanium alloy, and annealing, solid solution and the timeliness thermal treatment of different trade mark titanium alloys; Comprise body of heater 1 and heating controller; By top, following, the left side, the right side, front, six bodies of heater 1 that side panel constitutes in back, the intermediary cavity forms burner hearth 2, and at least one side panel is provided with packaged type fire door 3 therein; Fire door 3 rotates or moves up and down under PWR PLT drive, with body of heater 1 on the fire door door opening offered on this side panel cooperate and seal.
Inboard at six side panels of body of heater 1 all is provided with electric heater 4, and the heating of energising back is with heating furnace 2, and the energising or the outage of heating controller control electric heater 4 adopt existing Power Regulation temperature controlling system to satisfy rate of heating and uniformity requirement.
The outside of six side panels is furnace shells 11, and furnace shell adopts the shaped steel and the sheet material of the specification that meets the requirements to be welded.On ME, after the furnace shell employing intensified process as outside plate, embed the production method of welding, weld seam can't see in the furnace shell outside.Furnace shell 11 not only has enough heat resistances and stiffness.Be heat-resisting furnace lining 12 in the furnace shell 11, adopted the furnace lining structure of flat-top, composite shape matl.The heat-resisting furnace lining 12 of top side plate (furnace roof), the left side, the right side, front, back side plate (four side walls) is used the aluminum silicate fibre product material.Following side plate (furnace bottom) is used insulating brick, i.e. high-strength light brick and high-alumina refractory brick.Movably the stove gate frame of fire door 3 damages because being subject to collision, adopts the low cement high-strength degree mould material of steel fiber, the step pouring moulding.
Furnace roof is selected the prefabricated profiled cellucotton brick of 1400 ℃ of classification temperature for use, and backing is with the moist needle punched blanket of 1260 ℃ of classification temperature, and the anchoring piece 13 that cotton brick is reinstated heat-resisting steels matter together with lining blanket one is fixing, reinforces on the steel construction piece on furnace shell top.
The heat-resisting furnace lining (being thermal insulation layer) of four side panels of burner hearth (four side walls) and fire door is used the magnesiumcarbonate insulation quilt, moist needling fiber blanket fissure of displacement lay-up.Flame retardant coating is used pressure forming, (the polycrystalline ceramic fiber plate of 350 ㎏/m3) of the high-density after special the processing.Seam is with the special-purpose high temperature sticker of import between the plate, the splicing of brushing back, heating cure and being integral.
Rationally and on the appropriate position with the anchoring piece 13 of many high temperature steel materials, all connect heat-resisting furnace lining and be positioned on the furnace shell 11 of steelwork.The front end of all anchoring pieces 13 all hiddenly can not produce high temperature oxidation in heat-resisting furnace lining 12, adapt to 1100 ℃ high temperature, can effectively prolong its work-ing life.Anchoring piece 13 is in hot down free expansion, do not limit or compresses furnace lining, and furnace lining is not damaged.
At the top of burner hearth 2, on the promptly top side plate (furnace roof), be provided with several recirculation blowers 5, blowing is played stirring action to increase temperature uniformity to stir the air in the burner hearth 2 in burner hearth 2 under slave mode; Recirculation blower 5 starts the back forces furnace atmosphere circulation, strengthens the convection current conduction of low-temperature heat section, improves the heat conducting uniformity coefficient of high temperature section.M R for ease, on structure design, recirculation blower 5 is set to an one-piece construction together with parts such as impellers, can pack into and takes out from integral body on the furnace roof.Through repeatedly testing proof: the box resistance heading furnace of high-temperature titanium alloy, increasing the blower fan pump circulation is to guarantee one of body of heater thermal property good technical measure.
The heating original paper of electric heater 4 has wire spiral and two kinds of shaping prods of resistive band, comprehensively weighs from component life, power distribution and the mode that installs and fixes, and it is better that the utility model employing resistive band turns to ripple struction.
Although wire spiral and resistive band are under the condition of high temperature, with same wavelength, pitch compares, and the wire spiral distortion is less, and elongation and distortion can be ignored.And the resistive band distortion is bigger, but resistive band has significant advantage on raising element work-ing life and raising radiation efficiency.
On the resistive band fixed form, adopt following three kinds of traditional ways in custom on the fibre furnace lining: (1) is pre-buried porcelain tube hook in layer of fibers; (2) spiral pottery nail hook (3) increases a high temperature steel erecting frame on the furnace lining upper layer, hook cover porcelain insulator on the frame.
But through facts have proved: aforesaid way is for the titanium alloy of large span temperature use range, and is not suitable.Because it is coarse and crude that furnace lining technology is made, the Ceramic fitting quality is too poor, is easy to brokenly crisp under the rapid heat cycle state.It is hot that serious the contraction takes place in layer of fibers down, the through metal oxidization burning loss, and distortion, the well heater distortion all possibly cause the short circuit of local or large area region, goes wrong frequently, and equipment possibly normally move hardly.The utility model is to select for use the heat-resistant alloy wire of high nickel content (how much nickel content content please replenish greater than) to make the hook of resistive band on the titanium alloy resistance furnace.In the high-density polycrystalline ceramic fiber plate of pressure forming, be embedded into hook, adopted the hook technique for fixing of anti-rotation.Controlled the trend of resistive band torsional deformation effectively hot time.The titanium alloy resistance heading furnace of the utility model, adapt to titanium alloy from low temperature to temperature again to pyritous heats forged or thermal treatment needs, stove just can satisfy simultaneously from 350～1150 ℃ of each different temperature sections heat, heat treated needs.
According to actual needs, the process furnace of the utility model can be set to movable furnace bottom, promptly joins furnace bottom from walking haulage gear (like Fig. 1, shown in 2).According to the different user arts demand, can be equipped with supplementary unit like quenching tank and blower fan cooling water recirculation system etc.; And, can pick and place titanium alloy workpiece by the proportioning mechanical manipulator, pallet of proportioning in burner hearth 2, titanium alloy workpiece is placed on the pallet, lifts pallet with mechanical manipulator, and pallet is shifted out burner hearth 2 (like Fig. 3, shown in 4) together with titanium alloy workpiece integral body.
