Background technology
The pack alloy goods in process of production must be through operations such as preheating, fusing and die casting.Wherein, melting process is most important, directly influences the quality of Al-alloy products.At present, the melting of aluminium alloy is normally carried out in melting furnace, existing melting furnace; comprise in the middle of body of heater with heat-insulation layer, the body of heater being one to be the burner hearth of cavity-like; be provided with a crucible in the burner hearth, the crucible outside is provided with heater strip, also is provided with temperature measuring equipment and protective gas input unit etc. simultaneously.What wherein temperature measuring equipment was taked is the mode of indirect thermometric, is about to the linear pattern thermocouple and passes body of heater and be inserted in the burner hearth, infers the temperature of aluminium liquid in the crucible by measuring fire box temperature, and then carries out the temperature control of fusion process.Its measurement be fire box temperature rather than measure temperature of aluminum liquid in the crucible that the temperature of the temperature of burner hearth and aluminium liquid is inconsistent.In order to guarantee the abundant of pack alloy fusing, the temperature of burner hearth need be set in 950 ± 20 ℃ usually, is heated to 620 ℃ of left and right sides Shi Rongqing at aluminium liquid, and is incubated 2 hours in molten clear back, and is identical with this aluminium liquid refining quality that guarantees each position in the crucible.But fusing time is long like this, and not only power consumption consumption is excessive, and measurement result neither be very accurate, and error is excessive.And the temperature of aluminium liquid directly influences the die casting product quality, can't accurately control the temperature of aluminium liquid, and quality of die casting is uncontrollable equally, causes percent defective higher.
The utility model content
The purpose of this utility model just provides that a kind of energy consumption is low, temperature is controlled accurate aluminium alloy melting furnace.
The purpose of this utility model can realize by following technical proposal: a kind of aluminium alloy melting furnace, comprise body of heater and the loam cake that is arranged on the described body of heater, described body of heater inner chamber is divided into charge door, the heat tracing chamber that communicates and ladles out aluminium mouth three parts, and it also comprises being arranged to cover on described and is used for the indoor aluminium alloy of described heat tracing is carried out the burner of radiation heating and the temperature control equipment that is electrically connected with described burner.
The utility model also can further be realized by the following technical programs: described electrical control gear is made up of atmosphere temperature controller and temperature of aluminum liquid controller.
Further, cover to be provided with on described and be positioned at the indoor atmosphere temperature sensor of described heat tracing, described atmosphere temperature sensor is connected with described atmosphere temperature controller.
Further, described ladling out is provided with the temperature of aluminum liquid sensor in the aluminium mouth, and described temperature of aluminum liquid sensor is connected with described temperature of aluminum liquid controller.
Further, described burner is made up of the combustion gas flat-flame burner and the heat exchanger that are connected.
Further, described charge door, heat tracing chamber and the bottom surface of ladling out the aluminium mouth tilt from high to low.
The effect of this patent is: aluminum alloy melting holding furnace of the present utility model, added electrical control gear, by temperature of aluminum liquid sensor and atmosphere temperature sensor senses to aluminium liquid or furnace atmosphere temperature be sent to temperature control equipment, by the temperature that temperature of aluminum liquid controller in the temperature control equipment and atmosphere temperature controller come according to feedback the calory burning of the combustion gas flat-flame burner in the burner is regulated, and then the heating-up temperature of adjustment heat exchanger, effectively utilized energy consumption.Melting and heat preservation stove of the present utility model has kept conventional radial pattern holding furnace characteristic of low energy consumption, and reasonably optimizing radiation heating area improves melting and heat preservation efficient, adapts to the little tonnage alloy product of small lot production demand, reduce production costs, and energy savings.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the schematic diagram of the utility model side.
The specific embodiment
Embodiment: small gas aluminum alloy melting holding furnace of the present utility model is described in conjunction with Fig. 1 and Fig. 2, body of heater 1 inner chamber is divided into heat tracing chamber 3 and lays respectively at the charge door 4 of 3 both sides, heat tracing chamber and ladle out aluminium mouth 2 three parts, and heat tracing chamber 3 is respectively with charge door 4 with ladle out aluminium mouth 2 and communicate.Charge door 4, heat tracing chamber 3 and the bottom surface of ladling out aluminium mouth 2 tilt from high to low, are convenient to the slowly trickling in ladling out aluminium mouth 2 naturally of aluminium liquid.Three chambers are equipped with top cover, and wherein, the loam cake 11 of heat tracing chamber 3 is provided with and is used for aluminium alloy is carried out the burner of heat tracing and the electrical control gear that is electrically connected with burner.Be integrated with atmosphere temperature controller 12 and temperature of aluminum liquid controller 13 in the electrical control gear.
Burner is made up of combustion gas flat-flame burner 10 that is connected and heat exchanger 12, indirectly the molten aluminium alloy in the heat tracing chamber 3 is carried out heat tracing by combustion gas flat-flame burner 10 by heat exchanger 12, heat tracing chamber 3 heating surface areas are big, and heating-up temperature is even, and surperficial scaling loss is low.
Can control heating-up temperature automatically in order to make combustion gas flat-flame burner 10, prevent the molten aluminium alloy scaling loss, the atmosphere temperature sensor 11 that is positioned at heat tracing chamber 3 superjacent air spaces is installed on loam cake 11, this atmosphere temperature sensor 11 connects atmosphere temperature controller 12, and atmosphere temperature controller 12 connects combustion gas flat-flame burner 10.Be provided with temperature of aluminum liquid sensor 8 in ladling out aluminium mouth 2, this temperature of aluminum liquid sensor 8 is electrically connected temperature of aluminum liquid controller 13, and temperature of aluminum liquid controller 13 is connected with combustion gas flat-flame burner 10 again.Therefore, temperature of aluminum liquid sensor 8 and atmosphere temperature sensor 11 can detect the temperature of furnace atmosphere or aluminium liquid constantly, when furnace atmosphere or temperature of aluminum liquid are higher, by atmosphere temperature controller 12 and temperature of aluminum liquid controller 13 control combustion gas flat-flame burners 10 turn down power output than or stop heating.When furnace atmosphere or temperature of aluminum liquid are low, equally also by atmosphere temperature controller 12 and temperature of aluminum liquid controller 13 control combustion gas flat-flame burners 10 raise output than or begin heating.Small gas aluminum alloy melting holding furnace thermal efficiency height of the present utility model, flexible and convenient operation satisfies the user's request of abortion amount.
