Abstract
The utility model relates to a multi-zone reheating furnace relating to the field of reheating furnaces. The multi-zone reheating furnace comprises a furnace body, wherein the furnace body comprises a furnace housing which is of a rectangular box type structure and a fireproof insulating layer, wherein a hearth of the furnace body is provided with at least six furnace zones along the axial line of the hearth, electric heaters are arranged in the furnace zones, and the temperature in the furnace zone close to a furnace inlet of the hearth is lower than that of the adjacent furnace zone in every two adjacent furnace zones. The multi-zone reheating furnace is simple in structure and convenient to operate, and is capable of effectively reducing the energy consumption and increasing the heat treatment qualified rate during application.
Description
[technical field]
The utility model relates to the process furnace field, especially relates to a kind of heat treatment heating furnace with multi-stage type body of heater.
[background technology]
Known, heat treatment heating furnace is a kind of for the stove and accessory that metal parts is heat-treated, many employing electrically heated are now carried out heat temperature raising to the burner hearth of process furnace, make the temperature in the burner hearth meet the requirements of thermal treatment temp, thereby metal parts is heat-treated operation, with the mechanical property of corresponding raising metal parts; Yet, in long-term practical application, find, because what conventional electric heating formula process furnace adopted when thermal treatment is after with the uniform heat temperature raising of whole burner hearth entirely, just will need heat treated metal parts to be conveyed into and carry out normal heat treatment operation in the burner hearth, namely not only the energy consumption of whole burner hearth is higher in this process, and metal parts is gone back the phenomenon that easily deforms or ftracture because temperature variation is too fast when just entering burner hearth, therefore, it is higher that present thermal treatment electrical heater has production cost, the defective that the thermal treatment qualification rate is lower.
[summary of the invention]
Not only simple in structure, easy to operate for the not enough described process furnace that overcomes in the background technology, but also can in application, effectively reduce energy consumption and improve the thermal treatment qualification rate, the utility model discloses a kind of multi-zone reheating furnace.
For achieving the above object, the utility model adopts following technical scheme:
A kind of multi-zone reheating furnace, described process furnace comprises the body of heater body; Described body of heater body comprises furnace shell and the refractory insulating layer of rectangle case structure, the burner hearth of body of heater body divides at least along the burner hearth axis and sets out six sections stove districts, be equipped with electric heater in these stove districts, and in every two neighboring sections stove district, the stove district temperature that corresponding close burner hearth advances fire door is lower than the temperature in adjacent stove district.
Described multi-zone reheating furnace, described furnace shell two ends are welded with furnace panel; Described furnace panel is equipped with the firedoor frame of gradient.
Described multi-zone reheating furnace, described refractory insulating layer is made by resistant to elevated temperatures high purity ceramic fiber rock wool.
Described multi-zone reheating furnace, described burner hearth are arranged with six sections stove districts, and the both sides in every section stove district and bottom are equipped with well heater.
Described multi-zone reheating furnace is equipped with temperature-control heat couple and overtemperature caution thermopair in the described stove district.
Described multi-zone reheating furnace, described burner hearth bottom is provided with groove, is placed with the brick of putting for the support well heater in the groove.
Described multi-zone reheating furnace, described groove notch is provided with the carbonated lime brick stove cover plate.
Described multi-zone reheating furnace, the mouse cage type structure of described well heater for being made by OCr25A15 alloy silk.
Owing to adopt aforesaid technical scheme, the utlity model has following beneficial effect:
Multi-zone reheating furnace described in the utility model is simple in structure, easy to operate, described process furnace utilizes the multi-stage oven district to realize that the progressive of temperature heats, thereby not only when using, effectively reduced the energy consumption of whole burner hearth, but also effectively avoided the phenomenon of metal parts contingent distortion or cracking when just entering burner hearth, and then production efficiency and heat treated qualification rate have been improved accordingly.
[description of drawings]
Fig. 1 is synoptic diagram of the present utility model.
Among the figure: 1, furnace shell; 2, refractory insulating layer; 3, burner hearth; 4, advance fire door.
[embodiment]
Can explain the present invention in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope, and the utility model is not limited to the following examples;
1 described multi-zone reheating furnace by reference to the accompanying drawings, described process furnace comprises the body of heater body; Described body of heater body comprises furnace shell 1 and refractory insulating layer 2; Described furnace shell 1 is made as the rectangle case structure of being convenient to mark off six sections stove districts, for ensureing resistance to air loss and the reliability of furnace shell 1 two ends fire door, is welded with furnace panel at the furnace shell two ends, and the foundry furnace doorframe of constant slope is installed on the furnace panel simultaneously; For effectively improving the performance of fire resistant heat preserving, described refractory insulating layer 2 is made by resistant to elevated temperatures high purity ceramic fiber rock wool; The burner hearth 3 of described body of heater body is divided into six sections stove districts that closely link to each other uniformly along burner hearth 3 axis, and the both sides in every section stove district and bottom are equipped with well heater, temperature-control heat couple and overtemperature caution thermopair, thereby when utilizing well heater that metal parts is evenly heated, also guaranteed effectively that by temperature-control heat couple and overtemperature caution thermopair the temperature in every section stove district is normal; For reducing the energy consumption of whole burner hearth 3 in heat treatment operation, the stove district temperature that corresponding close burner hearth advances fire door 4 in every two neighboring sections stove district in the described process furnace is made as the temperature that is lower than its adjacent stove district, thereby make need heat treated metal parts in the heating stroke can by transporting mechanism at the uniform velocity by low temperature to high temperature transition gradually, and then effectively avoided the phenomenon of metal parts contingent distortion or cracking when just entering burner hearth 3;
For ease of in burner hearth 3, placing well heater, can be provided for card in the bottom of burner hearth 3 and put the groove of putting brick, the brick of putting that card is put in the groove is used for the support well heater, namely utilizes the brick of putting that firmly is placed in the groove to ensure that effectively the temperature of well heater can not be distributed to the outside by burner hearth 3 bottoms; In addition, can also lay the carbonated lime brick stove cover plate at the groove notch, namely utilize the carbonated lime brick stove cover plate to block the well heater upper side, thereby effectively avoided burner hearth 3 internal cause high temperature and the oxidation cast that the produces back of dropping contacts with well heater, cause the phenomenon generation of well heater short circuit; For ease of quick dismounting and change well heater, described process furnace has adopted the well heater of the mouse cage type structure of being made by OCr25A15 alloy silk, is the purpose of the well heater of replaceable single damage thereby reached in actual applications without blowing out.
The utility model does not describe part in detail for prior art, so the utility model is not described in detail.
