Split type continuous type heat-treatment furnace

Technical field

It the utility model is related to a kind of continuous type heat-treatment furnace, more particularly to a kind of split type continuous type heat-treatment furnace.

Background technology

Traditional continuous type heat-treatment furnace mainly includes a body of heater, the bottom laying insulating brick-layer in body of heater, is protecting Twice high-temperature flame-proof brick wall is provided with along body of heater length direction in warm brick layer, burner hearth, stove are formed between twice high-temperature flame-proof brick wall The vault of thorax is one layer of highiy refractory brick, thermal insulation fire-resistant brick wall is further respectively had on the outside of twice high-temperature flame-proof brick wall, in stove Full refractory fiber cotton is filled between wall and hearth outer wall in vivo.Fire brick layer is also equipped with the insulating brick-layer of burner hearth bottom, Fire brick layer is provided with boiler tube, and the both ends of boiler tube extend to the outside at body of heater both ends.In the overhung tubulose heating wire of burner hearth, The both ends of tubulose heating wire are extended to outside body of heater；Thermocouple is provided with the side wall of body of heater, thermocouple is inserted in burner hearth.This biography The continuous type heat-treatment furnace of system can just be repaiied after the insulation material on upper strata all must be removed when needing repairing to maintaining hearth Lay insulation material after good again again, whole maintenance process will time-consuming, greatly affected Workshop Production process；Tearing open simultaneously Except when, some insulation materials, the fragment of refractory brick, which can drop to, makes it impaired in burner hearth and on tubulose heating wire；Fire resisting in burner hearth Be easy to after brick long-time use cracking, fragment drop, had a strong impact on the production environment in burner hearth.Such a traditional continuous type Heat-treatment furnace maintenance is difficult, and heat insulation effect is poor, and service life is short.

The content of the invention

For disadvantages mentioned above, the purpose of this utility model is to provide one kind and is easy to repair, high insulating effect and service life Long split type continuous type heat-treatment furnace.

To achieve the above object, technology contents of the present utility model are a kind of split type continuous type heat-treatment furnace, including stove Body, body of heater include upper furnace body and lower furnace body；Compressed between upper furnace body and lower furnace body using quick-release type hold-down bolt；In the whole of body of heater Individual inwall is provided with one layer of heat preservation blanket；On the insulation blanket of the bottom of lower furnace body twice high-temperature flame-proof is provided with along body of heater length direction Brick wall, twice high-temperature flame-proof brick wall are that Parallel Symmetric is provided separately, between the madial wall and high-temperature flame-proof brick wall of lower furnace body Provided with heat-insulation layer；It is sequentially provided with lower furnace body insulating brick-layer, lower furnace body refractory brick from the bottom up between twice high-temperature flame-proof brick wall Layer, the refractory brick supporting station perpendicular to body of heater length direction is uniformly arranged on lower furnace body fire brick layer along body of heater length direction, Lower furnace body heating module is provided between refractory brick supporting station, refractory brick supporting station is higher than lower furnace body heating module, in refractory brick Boiler tube is laid on supporting station, the both ends of boiler tube extend to the outside at body of heater both ends；Insulation is respectively equipped with two inner sides of upper furnace body Module, the interval between heat preservation module is corresponding with the interval between lower furnace body high temperature refractory brickwork, between heat preservation module Upper furnace body insulating brick-layer, upper furnace body fire brick layer, upper furnace body heating module are sequentially provided with from top to bottom, in lower furnace body heated mould Heating wire is embedded with block and the upper furnace body heating module, heating wire end extends to the outside of body of heater and Intelligent temp controlled instrument adds Controllable silicon connects；High-temperature flame-proof brick wall forms burner hearth with lower furnace body heating module and upper furnace body heating module, at the top of body of heater It is extend into provided with thermocouple in the burner hearth.

Insulation of the present utility model and refractory material use crystal fibre.This material heat insulation effect is splendid, is not likely to produce Dust environmental protection, the advantage that the insulation material changed is recyclable and valuable low-quality is light.

Upper furnace body need to only be removed and burner hearth can be repaired by the utility model when needing repairing, and to upper furnace body Globality does not damage, and there will not be insulation material fragment and drops；Heating wire is directly embedded in heating module, protected well Protect that heating wire is injury-free and heat energy is not suffered a loss；And electric-heating-wire-heating is used simultaneously up and down, burner hearth is formed one and be heated Balanced overall heating region, adds SCR control in electric part using Intelligent temp controlled instrument, adds feedforward and feedback work( Can, the change to furnace temperature has certain foresight, improves the degree of accuracy of Control for Kiln Temperature so that austenite phase is occurring for steel wire Tissue evenly, is advantageous to the raising of final product quality during change；And the smooth control to current of electric heating wire is realized, reduce to fire proofed wood Thermal shock caused by material, extend the service life of stove.

Compared with prior art, the utility model is advantageously easy to maintenance, high insulating effect, improves hot place Manage final product quality and increase the service life.
