Abstract
The utility model relates to a non-ferrous metal melting furnace, comprising a furnace body base, an upper furnace body, a lower furnace body, an inner layer furnace body and heating elements. The inner layer furnace body uses refractory concrete with compact texture and is integrally formed into pool shape, the external shape of the inner layer furnace body is conform to the inner shape of the lower furnace body and is embedded in the lower furnace body, a plurality of heating elements are directly installed on the upper part of the upper furnace body, and the lower furnace body is installed on the furnace body base. The utility model can ensure the quality of metal melting liquid and has the advantages of high speed of warming, high efficiency of heat transfer, good effect of energy saving, convenient simultaneous operation and long service life of furnace bodies, and the utility model is an ideal non-ferrous metal intensively melting furnace.
Description
The utility model relates to a kind of non-ferrous metal melting stove, particularly a kind of pond formula melting furnace that does not have the cast iron crucible.
In the non-ferrous metals casting process, must earlier non-ferrous metal melting be become molten metal.Existing non-ferrous metal melting device is that the crucible that is used to hold molten metal is housed in the refractory oven of body of heater, and between furnace wall and crucible heating element heater is set.There is following shortcoming in this heating furnace: 1. the normal phase of crucible is in the hot environment, easily because of the oxidative attack of being heated damages, needs regular replacing crucible in the use, and cost is higher; 2, the irony in the cast iron crucible can penetrate in the non-ferrous metal liquid, seriously reduces the quality of molten metal; 3. indirectly to the non-ferrous metal heating, it is slow to conduct heat outside crucible for heating element heater, and the thermal efficiency is low; 4. be subjected to the restriction of crucible capacity, influence large-scale metal molten.
Problems such as the purpose of this utility model provides a kind of non-ferrous metal pond formula melting furnace, and crucible is not set in its body of heater, and the thermal efficiency that can solve existing non-ferrous metal melting stove existence is low, service life is short.
The purpose of this utility model is achieved through the following technical solutions: non-ferrous metal pond formula melting furnace comprises base of furnace body, upper furnace body, lower furnace body, internal layer body of heater and heating element heater, the internal layer body of heater builds up a pond shape by the refractory concrete integral body of quality densification, its profile is consistent with the interior shape of lower furnace body, and is embedded in the lower furnace body; Rear upper end at the internal layer body of heater is provided with at least one charging door, and lower front is provided with the fluid cast gate; There are several heating element heaters directly to be installed on the top of upper furnace body; Lower furnace body is installed on the base of furnace body.
Owing in the body of heater of the present utility model crucible is not set, directly constitute its internal layer with refractory material, do not exist crucible to damage problem, can not reduce the quality of molten metal, and help prolonging the service life of stove.Heating element heater directly is installed in the upper furnace body, makes metal molten by direct radiation of heating element heater and intermetallic heat conduction.
The utility model has the advantages that: programming rate is fast, the heat transfer efficiency height, and good energy-conserving effect can guarantee the quality of molten metal, and is simultaneously easy to operate, the body of heater high life is that a kind of desirable non-ferrous metal is concentrated melting furnace.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure, 1. base of furnace body 2. damping springs 3. internal layer bodies of heater 4. lower furnace bodies 5. upper furnace bodies 6. protective covers 7. charging 8. motors 9. reductors 10. fluid cast gates 11. power transmission shafts 12. heating element heaters 13. sleeve pipes 14. steel wires
The non-ferrous metal pond formula melting furnace of present embodiment is made of base of furnace body (1), upper furnace body (5), lower furnace body (4), internal layer body of heater (3) and heating element heater (12), internal layer body of heater (3) builds up a pond shape by the refractory concrete integral body of quality densification, its profile is consistent with the interior shape of lower furnace body (4), and is embedded in the lower furnace body (4); Rear upper end at the internal layer body of heater is provided with a charging door (7), and the corresponding site that it passes lower furnace body leads to outside this melting furnace, is used for reinforced and scarfing cinder; The below of internal layer body of heater front portion is provided with fluid cast gate (10); There are several heating element heaters (12) directly to be installed on the top of upper furnace body (5); Lower furnace body (4) is installed on the base of furnace body (1).
The heating element heater of present embodiment (12) is several Elemas; the two ends of Elema be with that protective casing (13) is arranged in a row the heating element heater Elema in horizontal direction or mutually vertical-horizontal arrange two rows and be installed in upper furnace body top, can strengthen the thermal cycle in the stove like this.
Described upper furnace body (5) is made by no asbestos calcium silicate board with microporous.
Described inner furnace body (3) is made by steel fibre refractory concrete integral body.
Furnace binding of the present utility model can be the non-movable piston formula, and lower furnace body and base of furnace body also can be mechanical tilting type structure for fixedlying connected.Embodiment shown in the drawings is the tilting type furnace binding.Motor (8) is housed on base of furnace body (1), this motor is connected with reductor (9), reductor (9) is connected with power transmission shaft (11), steel wire rope (14) is housed on the power transmission shaft (11), the other end of this steel wire rope is connected in the rear end, bottom of lower furnace body (4), also is equiped with damping spring (2) between the bottom of lower furnace body and the base of furnace body (1).When toppling over molten metal, starter motor (8), reductor (9) drive power transmission shaft (11) work, by steel wire rope (14) are sling in the rear portion of lower furnace body (4) and vert promptly pourable molten metal.
For ease of outside stove, toppling over molten metal, and reduce pond prodelta clay liquid as far as possible, can at the bottom of the pond of internal layer body of heater, design certain gradient, make operation more convenient.
In addition, outside upper furnace body,, use safely with the protection heating element heater with the corresponding position installing of heating element heater protective cover (6).
