Benefit increases, and the Research on Weldability enabling aluminum alloy to is also therewith deeply.
Aluminium alloy melts, holding furnace is that have most important equipment in aluminium alloy manufacturing field, and bulk solid-state aluminium ingot needs
To be molten into molten condition in aluminium alloy melting, holding furnace, and to be maintained at uniform temperature, to maintain its molten condition, be carried
For molten aluminium alloy form required Al-alloy products after carrying out die casting.Body of heater is the important component part of holding furnace.
Viscosity during 750 DEG C of aluminium alloy is 0.104Pa S, and this viscosity (0.10Pa S) with water when 20 DEG C is quite
Close, the mobility of therefore molten aluminium alloy is fabulous, easily penetrates into the inside of furnace lining.Holding furnace furnace bottom is in conditions such as rapid heat cycles
Low angle crack occurring, once occurring, aluminium liquid can be penetrated in these cracks quickly, causing crack growth, short texture and breaking
Bad.Additionally, for the flat-bottom structure holding furnace furnace bottom of tradition use, aluminium liquid is identical to the depth of erosion of furnace bottom, can cause big face
Furnace lining material peel off, cause furnace lining material bulk life time to decline to a great extent, cause production safety hidden danger.In order to solve above asking
Topic, needs the improvement by furnace binding.
Content of the invention
The purpose of the present invention is just to provide for a kind of holding furnace for containing aluminum fluid, simple process, working stability, makes
Use life-span length.
To achieve these goals, the technical solution used in the present invention is as follows：
A kind of holding furnace for containing aluminum fluid, including insulation furnace body, insulation furnace body includes furnace wall and furnace bottom, the bottom of furnace wall
Portion is connected by furnace bottom, and furnace bottom is in invert shape, and furnace wall and furnace bottom are constituted by working lining, impervious layer, impervious barrier and heat-insulation layer,
The bottom of insulation furnace body is provided with storage bin, and storage bin passes through to permeate pipeline connection insulation furnace body, the top of infiltration pipeline
Connect in impervious layer, the surface of insulation furnace body is provided with observation window, and the side of observation window is provided with temperature indicator, heat-insulation layer
Be made up of rock cotton board, steel mesh sandwich sheet material and styrofoam it is characterised in that：Heat insulation layer structure is followed successively by one layer of rock inside-out
Cotton plate, two-layer steel mesh sandwich sheet material, two-layer steel mesh sandwich sheet material constitutes a hollow layer, is filled with polyphenyl in hollow layer
Plate.
Further improvement of the present invention, working lining is arranged on the inside of insulation furnace body, and the outside of working lining is impervious layer,
The outside of impervious layer is impervious barrier, and the outside of impervious barrier is heat-insulation layer.
The thickness of further improvement of the present invention, furnace wall and furnace bottom is 550mm-750mm.
Further improvement of the present invention, the thickness of the rock cotton board in heat-insulation layer is 10-100mm, steel mesh sandwich sheet material
Thickness is 10-50mm, and the thickness of the hollow layer that two-layer steel mesh sandwich sheet material is constituted is 10-50mm.
Beneficial effects of the present invention：The holding furnace for containing aluminum fluid of present disclosure, furnace bottom adopts arch design,
Effect is good, can effectively solving castable produce in use stress, volume cold and hot change the problems such as, additionally, rely on fall
The design of domes, in the presence of its own shearing force, it is possible to reduce the formation in low angle crack, prevent short texture and
Destroy, additionally, compared to flat-bottom structure, domes shearing force everywhere is different, and alloy molten solution can be avoided to corrode phase
Same depth, and cause serious peeling phenomenon, the life-span of liner can be obviously prolonged after use；In bottom of furnace body stationary storage case,
The destruction to body of heater can be reduced by seepage metallic solution afflux inside it.
