Abstract
The utility model provides a hot-wall tempering furnace and belongs to the technical field of heat treatment, aiming at solving a problem of an existing tempering furnace that heating is uneven because a heating electrode is easily consumed. The hot-wall tempering furnace comprises a furnace body and a heating well, wherein a furnace cover is arranged at the top end of the furnace body; the furnace body is arranged in a well pit of the heating well; both the inner wall and bottom of the well pit are provided with heating bodies; and spacer devices are arranged between the heating bodies and the furnace body to form clearances the heating bodies and the furnace body. With the structures above, the hot-wall tempering furnace has the advantages that the furnace wall is heated uniformly, a constant-temperature state of the tempering furnace can be ensured; and the multi-point heating away used in the hot-wall tempering furnace can reduce energy consumption in comparison with a conventional electrode heating manner.
Description
Technical field
The utility model belongs to heat treatment technics field, particularly a kind of wall heating type tempering stove.
Background technology
The general snappiness metallic substance that forges need to carry out the processing such as heat, quench cooled, tempering.Tempering can change metal austenite grain size, eliminates stress, and makes grain refining, is the technological process of metal tools device necessity.
Traditional tempering stove operating method is: in a vertical well shape stove, add liquid medicine, pass into again positive and negative electrode, the high calorie that electrode produces is used for heating liquid medicine, finally workpiece is invaded to tempering in liquid medicine, but electrode easily consumes in high temperature, make electrode shorter and shorter, therefore the direct contacts electrode of the liquid medicine of tempering stove bottom, now, the temperature of liquid medicine is passed to lower end by upper end, the polarization of formation temperature very easily, it is different that mould product is incubated the hardness obtaining at different temperature, and the toughness of two sections, metal is also not quite similar.Electrode adopts the pattern of localized heat release simultaneously, and it is also very high therefore will being heated to its energy expenditure of certain high temperature, and therefore a kind of tempering stove of energy-saving ordinary-temp formula is badly in need of our exploitation.
Summary of the invention
The purpose of this utility model is problem high for existing tempering stove energy consumption, the constant temperature that is hard to keep, and has proposed a kind of wall heating type heating, simultaneously the average tempering stove of heated perimeter.
The purpose of this utility model can realize by following technical proposal: a kind of wall heating type tempering stove, it is characterized in that, it comprises body of heater and heated well, the top of body of heater is provided with bell, described body of heater is placed in the well of heated well, inwall and the bottom of well are equipped with heating member, be provided with and make the above-mentioned escapement that forms gap between the two between heating member and body of heater.
Described escapement comprises and is arranged on the interior caulking groove that well inwall is presented the multilayer insulating panel of lower leaf setting and is opened in well bottom, described dividing plate along well inwall circumferentially annular arrange, heating member is set on dividing plate, the width of heating member is less than spacer width.When body of heater inserts heated well, body of heater does not directly contact with heating member.
Described end to end with the heating member on layer dividing plate.
On described dividing plate, offer socket, in socket, be inserted with steady brace.
Described heated well adopts insulating fire brick to be built into.
Described heating member is nichrome wire.
The inwall of described heated well is provided with temperature tube, is provided with thermocouple in temperature tube.
Compared with prior art, this structure is heated evenly furnace wall, can guarantee the temperature constant state of tempering stove simultaneously; And the mode of employing multipoint heating, than traditional electrode heating, more can reduce energy consumption and produce.
Accompanying drawing explanation
Fig. 1 is this wall heating type tempering stove decomposing schematic representation;
Fig. 2 is the heated well structural representation of this wall heating type tempering stove.
In figure, 1, heated well; 2, steady brace; 3, inwall; 4, heating member; 5, interior caulking groove; 6, dividing plate; 6a, socket; 7, body of heater; 8, bell; 9, temperature tube.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, this wall heating type tempering stove comprises body of heater 7 and heated well 1, and the top of body of heater 7 is provided with bell 8, body of heater 7 is placed in the well of heated well 1, inwall 3 and the bottom of well are equipped with heating member 4, and the inwall 3 of well is provided with temperature tube 9, in temperature tube 9, is provided with thermocouple.As shown in Figure 2, between heating member 4 and body of heater 7, be provided with escapement, escapement comprises and is arranged on the interior caulking groove 5 that well inwall 3 is presented the multilayer insulating panel 6 of lower leaf setting and is opened in well bottom, dividing plate 6 is along circumferentially annular setting of well inwall 3, heating member 4 is set on dividing plate 6, the width of heating member 4 is less than dividing plate 6 width, and connects with heating member 4 head and the tail on layer dividing plate 6.On dividing plate 6, also offer socket 6a, assign the steady brace 2 that is useful on spacing heating member 4 in socket 6a, described heated well 1 adopts insulating fire brick to be built into, and heating member 4 is nichrome wire.
Body of heater 7 is lifted up in heated well 1, then at the interior injection liquid medicine of body of heater 7, given heating member 4 energising heating, make liquid medicine reach certain temperature, finally open bell 8 and workpiece is put into liquid medicine be incubated, this wall heating type structure is heated evenly body of heater 7, and tempered martensite's state of workpiece tends towards stability.Aforementioned barriers 6 can adjacent two heating member 4 of barrier and is made it can not touch mutually, and the width that dividing plate 6 width are greater than heating member 4 simultaneously can make again body of heater 7 directly contact with heating member 4, and assurance body of heater 7 is without localized hyperthermia.
Should be appreciated that, in claims of the present utility model, specification sheets, all " comprising ... " is all interpreted as open implication, and namely its implication is equal to " at least containing ... ", and should not be construed as enclosed implication, its implication should not be construed " only comprising ... ".
