Embodiment
The present invention will be further described with reference to the accompanying drawings and detailed description.
As Figure 1-3, the cast insulation of the cast insulation stove disclosed by the invention with Tooth-locked Quick Closure door structure
Stove, including body of heater 11, door structure include the fire door 6 located at fire door, and fire door 6 is provided with handle 7, around provided with gear ring 5, fire door
Fire door swing arm 4 is provided with, fire door swing arm 4 is hinged or is pivotally connected with arm shaft 2, i.e. fire door swing arm 4 can rotate around arm shaft 2, swing arm
Axle is fixed on fire door support 1, and fire door band tooth flange 9 is provided with fire door, and the fire door band tooth flange 9 has and the phase of gear ring 5
The tooth mutually engaged, can realize locking/release of flange 9 and fire door by rotation, and the driving flange 9 of gear ring rotation driving 3 makes its rotation
Turn, fire door heat-insulation layer 8 is filled between fire door and flange 9, the inner side of flange 9 is provided with latch segment 10, realizes the positioning of flange rotary.
Cast insulation stove disclosed by the invention injects metal from fire door to holding furnace when in use, first with liquid-adding device
Liquid, after, fire door swing arm 4 is rotated along arm shaft 2 using handle 7, drive fire door 6 to enter fire door band tooth flange 9, then profit
Fire door band tooth flange 9 is driven its rotation, flange 9 is stopped the rotation and is locked after encountering latch segment 10 with gear ring rotation driving 3, this
Gear ring 5 on tooth and fire door on Shi Falan is intermeshed, and realizes the closing of door structure, after being pressurizeed to holding furnace,
Air pressure presses to fire door 6, fire door 6 is tightly pushed down flange 9, furthermore achieved that sealing, can now be cast.Using terminating
Heater exhaust release is incubated afterwards, and gear ring rotation driving afterwards 3 drives fire door band tooth flange 9 to make its rotation, makes tooth and stove on flange
Gear ring 5 on door no longer engages, and fire door swing arm 4 is rotated along arm shaft 2 using handle 7, drives fire door 6 to leave fire door band tooth method
Orchid 9, realizes the unlatching of fire door, as shown in figure 4, into next working cycles.
Meanwhile as a kind of preferable scheme, as shown in figure 5, being additionally provided with cast insulation stove furnace wall disclosed by the invention
With porose pipeline, gas is discharged in the space of furnace wall by the pipeline to convey gas by the hole on pipeline, is used for
Increase the pressure in furnace wall.Holding furnace disclosed by the invention includes body of heater and burner hearth, and aluminium liquid is filled in burner hearth, and body of heater includes outermost
The steel furnace shell of layer, ceramic fiber paper is filled with shell, nanometer felt is provided with ceramic fiber paper, is calcium silicate board with microporous in nanometer felt, then
It is soak layer and castable refractory working lining inside, wherein furnace shell provides necessary structural support, ceramic fibre for body of heater
Paper is located in furnace shell, prevents aluminium liquid from exosmosing, and calcium silicate board with microporous provides low-temperature insulation performance, and the flame retardant coating of internal layer directly contacts with aluminium liquid.
Be provided with calcium silicate board with microporous with porose airway tube, the airway tube has air inlet, and connects inert gas source, carry out low pressure,
When differential pressure or adjustable pressure casting, during melt is risen liquid mold filling and solidification toward inflation in cool-bag burner hearth, while gas is pressed into
In space in container furnace wall, to increase the pressure of furnace wall, the atmospheric pressure value in burner hearth and in furnace wall is 0-0.6MPa, equivalent to from
Both sides are pressurizeed to castable refractory working lining respectively, make in furnace wall and air pressure reaches balance in burner hearth, to reduce stove cavity pressure
Influence to working lining, after casting process terminates, in burner hearth be vented release when, while to furnace wall be vented release.Using above-mentioned
Method, the thickness of castable refractory working lining is significantly reduced, and holding furnace operational excellence, significantly reduce cost.
It is described above, only it is presently preferred embodiments of the present invention, not the present invention is imposed any restrictions, it is every according to the present invention
