Besides, the electric heat preservation furnace greatly increases heat preservation effect.
Description
Technical field
The utility model relates to a kind of electric holding furnace for aluminum alloy die-casting.
Background technology
Current, what electric holding furnace for aluminum alloy die-casting adopted is to go up the radiant type electric holding furnace, its mode of heating is that moist closet top bell heating resistance wire conducts heat to aluminium liquid to come aluminium liquid in the stove is realized insulation by the mode of radiation, because the characteristic of itself is limit, there are following several open defects:
1) adopt on the former resistance wire radiant type holding furnace because of accomplishing to be incubated the sealing fully of bell, air enters in the stove in heating process, therefore the aluminium liquid of chamber surface oxidization burning loss very easily in 900-1000 ℃ environment heats up, produce a large amount of aluminium slags (must clear up aluminium liquid surface scum weekly), otherwise equipment can't move normally and very easily damage;
2) because last radioactive mode of heating is that the heat that resistance wire sends conducts to aluminium liquid by radiation mode, and the holding furnace thermal efficiency is low, as untimely cleaning aluminium liquid oxide on surface, its heat conduction is obstructed even more serious.If therefore plant maintenance work is done badly, energy consumption more can significantly rise;
3) the aluminium liquid upper and lower temperature difference in the holding furnace is big.Because of last radiant type holding furnace temperature of aluminum liquid is to rely on the intensification chamber resistive heater evolution of heat of bell to conduct to aluminium liquid to be maintained, certainly will cause the upper and lower temperature difference very big (can reach 20-30 ℃ after tested) of aluminium liquid in the holding furnace like this, have a negative impact to temperature of aluminum liquid in the die casting production process is stable, thereby can't satisfy the technological requirement that die casting is produced.
Problems such as in sum, existing electric holding furnace for aluminum alloy die-casting also exists heat insulation effect poor, and energy waste is serious.
The utility model content
The purpose of this utility model provides a kind of electricity insulation that is used for aluminium alloy compression casting of high insulating effect, uses this electric holding furnace can greatly reduce the oxidation of aluminium liquid.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of electric holding furnace for aluminum alloy die-casting comprises body of heater, first electric heater, and the top of described body of heater is provided with bell, and described first electric heater is arranged on the side wall of furnace.
In the technique scheme, described bell is provided with second electric heater.
The utility model compared with prior art has following beneficial effect:
The utility model is owing to be arranged on electric heater on the side wall of furnace, and electric heater can directly stretch in the aluminium liquid like this, has avoided the waste of heat energy in the heat transfer process in the prior art.Improved heat insulation effect greatly.Because electric heater is arranged on the side wall of furnace, can realize the fully sealing of bell in addition, greatly reduce the oxidation in body of heater of aluminium liquid, avoid the waste of material effectively body of heater.
Description of drawings

Fig. 2 is the vertical view of electric holding furnace for aluminum alloy die-casting shown in Figure 1.
Fig. 3 be among Fig. 1 A-A to cutaway view.
Fig. 4 is an I place enlarged drawing among Fig. 3.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1～Fig. 4, electric holding furnace for aluminum alloy die-casting, comprise that the furnace wall that body of heater 1, described body of heater 1 are made by 4 layers of different materials makes, the top of described body of heater 1 is provided with bell 2, the sidewall of described body of heater 1 is provided with first electric heater 3, described first electric heater 3 is the impregnated electric heater, and the heater of this first electric heater 3 is one and becomes columniform cylinder 30.Stretch in this cylinder 30 in the aluminium liquid in the electric holding furnace.
Described bell 2 is provided with second electric heater 5, the utility model is provided with second electric heater 5 on bell 2 purpose is, when first electric heater 3 that is arranged on body of heater 1 sidewall (also being the impregnated electric heater) damages, can enable second electric heater 5 that is arranged on the bell 2 at once, prevent damage because of first electric heater 3, cause the temperature of aluminum liquid of whole body of heater 1 to reduce, make it can not enter follow-up production.
Because first electric heater 3 is directly stretched in the aluminium liquid, so just avoided the waste of heat energy in the heat transfer process in the prior art, improved heat insulation effect greatly.Because electric heater is arranged on the side wall of furnace, can realize the sealing fully of 2 pairs of bodies of heater 1 of bell in addition, greatly reduce the oxidation in body of heater 1 of aluminium liquid, avoid the waste of material effectively.Its experimental data sees Table 1:
Table 1
For the utility model, realize first electric heater 3 sealing be vital, good sealing can guarantee that aluminium liquid does not ooze out from first electric heater 3.The utility model also is provided with sealing device at the outer surface of first electric heater 3 for this reason, described sealing device comprises the first tapered stifled cover 9 that is coated on first electric heater, 3 outer surfaces, the outer surface of the described first stifled cover 9 is arranged with tapered plug 11, and the outer surface of described plug 11 is coated with the second tapered stifled cover 13.Described first, second stifled cover 9,13 all adopts alumina silicate to make, and plug 11 then adopts graphite to make.
Be understood that, the sealing device of the outer surface of first electric heater 3 can be the sealing device of other form, but comparatively speaking, then superior many of sealing device of the present utility model, because of its first stifled cover 9, plug 11, the second stifled cover 13 is taper, when the first stifled cover 9, plug 11, the gap appears arbitrarily between the two in the second stifled cover 13, and the outer surface of the second stifled cover 13 and body of heater 1 are when the gap occurring, can make the first stifled cover 9, plug 11, the second stifled cover 13 is towards body of heater 1 inner moving, make the gap be eliminated, thereby make first electric heater 3 of the present utility model be able to good sealing always, avoid aluminium liquid to flow out, prolonged service life of the present utility model greatly from first electric heater, 3 outer surfaces.
The tapered end of described plug 11 is provided with fixed mount 7, described fixed mount 7 comprises the briquetting 70 that is fixed in plug 11 ends, the sidewall of described briquetting 70 is provided with elastic support 72, described elastic support 72 is perpendicular to briquetting 70, the end of described elastic support 72 also is provided with compressing tablet 74, the other end of compressing tablet 74 is connected with pillar 76 by bolt, and pillar 76 is installed on the lateral wall of body of heater 1.
Convention, electric holding furnace in use for some time, work such as need overhaul, during maintenance, electric holding furnace need cut off the power supply and carry out at normal temperatures, and inevitably, sealing device can expand with heat and contract with cold, and the expand with heat and contract with cold consequence that causes of sealing device is that the gap appears in the outer surface and the body of heater 1 of sealing device, and aluminium liquid goes out to flow out from this gap.The end of plug 11 is provided with fixed mount 7, and this problem is avoided.It is as follows to trace it to its cause: when the gap appears in the outer surface of sealing device and body of heater 1, under the elastic reaction of compressing tablet, support is drawn close to plug 11 directions, thereby make briquetting promote plug 11 towards body of heater 1 inner moving, because plug 11 is tapered, thereby make the outer surface of sealing device and the gap that body of heater 1 occurs be eliminated once more, thereby realize sealing reliably.
