Description
Technical field
The utility model relates to a kind of air injection machine, especially relates to a kind of holding furnace of air injection machine.
Background technology
The course of work of air injection machine passes into low-pressure gas in holding furnace, in the mould of material melting in the crucible of holding furnace completed by stalk input casting machine, then completes metal casting by pressing mold.
The holding furnace one of existing air injection machine is melting pool type, is directly heated material by Elema, and another kind is the internal sealed holding furnace using cast-iron pot to add a cover.In use all there is certain shortcoming in these two kinds of holding furnaces.Melting pool type holding furnace adopts heavy castable to build burner hearth, although the basic Maintenance free of burner hearth, but because the entirety of stove is excessive, in use, stove is heated to material melting temperature (melting temperature of such as aluminium liquid is 700 DEG C) from normal temperature, needs to spend considerable time, for most of producer, between being all, section is produced, and the so long heat time is obviously not too applicable, has a strong impact on operating efficiency; In addition, owing to using Elema directly to heat material, the surface of metalliferous material easily forms oxide layer, causes waste.
Sealing cast-iron pot formula holding furnace in another kind of, heating is fast, heater strip is around around crucible, directly do not contact with metalliferous material, oxidation is few, but due to the crucible adopted be cast iron quality, metalliferous material is placed wherein, can produce corrode to the cast iron inwall of crucible, of long duration, crucible will be penetrated from inside to outside by corrode; Moreover irony enters inside aluminium liquid and can greatly reduce the mechanical strength of producing aluminium casting, has influence on product quality.In order to overcome corrode problem, general at crucible internal walls brush one deck cast paint at a lower temperature, isolate cast-iron pot inwall and molten metal, coating is generally tens hours effective time, so just requiring to want when will produce interval will stop after tens hours producing at every turn, etc. furnace drop to lower after, cleaning crucible internal walls, again could again produce after brush coating, this process generally wants 10 hours, also lose time very much, cannot continuous seepage.
Summary of the invention
Goal of the invention: the utility model object is for the deficiencies in the prior art, provides one to be rapidly heated, again can continuous seepage, without the external seal formula holding furnace of brush coating.
Technical scheme: air injection machine external seal formula holding furnace described in the utility model, comprise the shell of sealing, surrounded the burner hearth limited by described shell, the crucible be arranged in described burner hearth, the some heating element heaters be wrapped in outside described crucible, seal cover and stretch into stalk in crucible through described seal cover, described crucible is graphite crucible; Described seal cover comprises sealing external cover and inner sealing lid, described sealing external cover is fixing on the housing, described inner sealing lid is fixed on described sealing external cover, described sealing external cover and inner sealing lid match airtight described burner hearth, and described sealing external cover and all leave gap between inner sealing lid and described graphite crucible; Described inner sealing lid is provided with and rises fluid apertures, described stalk rises fluid apertures through described, extend in described graphite crucible.
In order to overcome crucible internal walls by the problem of molten metal corrode, adopt without the need to daub, non-maintaining graphite crucible; Again because graphite crucible can not pressurized, the original internal sealed bearing pressure by crucible is set to be born by shell the external seal formula of pressure; Coordinate complete airtight burner hearth by inner sealing lid and sealing external cover, inner sealing lid and sealing external cover all leave space with crucible simultaneously, now pressurize in stove, and the external and internal pressure of crucible is balanced, can not produce cracking due to the stiffness issue of graphite crucible.
Preferably, the heat-insulation layer be made up of insulation material is also provided with in described shell.
Preferably, described heating element heater is resistance heating wire.
Preferably, described heating wire is connected with temperature controller, is controlled switch and the power of described heater strip by described temperature controller.
Preferably, in the shell bottom described graphite crucible, be also provided with safety door, for discharging the leakage of described graphite crucible, protection burner hearth.
Beneficial effect: (1) crucible of the present utility model adopts graphite crucible, can realize crucible internal walls without the need to daub, non-maintaining object, do not affect the quality of product, the utility model is by heating element heater to crucible heating simultaneously, and heat up rapidly, operating efficiency is high; The utility model sealing external cover and inner sealing lid and crucible leave space in addition, bear pressure by shell, ensure that graphite crucible external and internal pressure is balanced, do not destroy crucible; (2) the utility model is provided with heat-insulation layer, promotes the heat insulation effect of holding furnace; (3) the utility model uses heater strip to crucible heating, and heating element heater does not directly contact with material, and oxidation is few, does not produce waste; (4) the utility model controls heater strip by temperature controller, realizes the object of temperature automatically controlled, automatic melting, automatic heat preserving.
