Abstract
The invention discloses a dual-layer sealing furnace cover for low-pressure casting. The dual-layer sealing furnace cover comprises an upper cover and a lower cover, wherein a plurality of fastening bolt spigots are formed in corresponding positions on the edges of the upper cover and the lower cover at uniform intervals; riser tube fixing ports are formed in the centers of the upper cover and the lower cover. The dual-layer sealing furnace cover is characterized in that a heat-resisting plate is sandwiched between the upper cover and the lower cover; the upper cover and the lower cover are fixed through a plurality of fixing bolts. The dual-layer furnace cover can be suitable for sealing a crucible flange as well as a furnace edge flange of an integral sealed furnace. The upper cover is isolated from the lower cover through a heat insulating material, so that transfer of heat is avoided, dissipation of the heat of molten aluminum from the furnace cover is reduced, and the temperature of the outer surface of the upper cover is prevented from rising.
Description
Technical field
The invention belongs to aluminum alloy low-pressure casting field, particularly structure and the thermal-insulating sealing of crucible or body of heater bell that body uses for low pressure casting.
Background technology
At present, the domestic low pressure casting using in aluminum alloy low-pressure casting field is the structure of individual layer one with crucible or body of heater body institute bell, and in stove, aluminium liquid thermal loss is larger, and bell hull-skin temperature is higher, and execute-in-place environment is bad; In order to improve on-the-spot operation present situation, design a kind of double-layer seal bell, can overcome monomer bell dissipated heat fast, the shortcoming that bell hull-skin temperature is high.
Summary of the invention
Object of the present invention is exactly defect and the deficiency existing for overcoming above-mentioned prior art, and provide a kind of simple in structure, easy to operate, can reduce bell hull-skin temperature, reduce the low pressure casting double-layer seal bell of aluminium liquid heat loss in stove.
The technical scheme adopting is:
A kind of low pressure casting double-layer seal bell, comprise upper cover and lower cover, upper cover and interval, corresponding section, lower cover edge offer multiple fastening bolt seams uniformly, the center of upper cover and lower cover offers stalk fixing port, it is characterized in that being folded with heat insulation refractory plate between described upper cover and lower cover, upper cover and lower cover are fixed by multiple set bolts.
Of the present invention mainly a little:
Double-layer furnace cover of the present invention applicable to the blue sealing of crucible method, is also applicable to integral sealing stove stove along flange seal.Because upper cover is spaced apart by heat-barrier material and lower cover, thereby avoid the transmission of heat, reduced aluminium liquid heat from the scattering and disappearing of bell, also avoided the raising of upper cover hull-skin temperature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
As shown in Figure 1, a kind of low pressure casting double-layer seal bell, comprise upper cover 2 and lower cover 4, upper cover 2 and lower cover 4 intervals, corresponding section, edge offer 4 fastening bolt seams 3 uniformly, the center of upper cover 2 and lower cover 4 offers stalk fixing port 5, between upper cover 2 and lower cover 4, be folded with heat insulation refractory plate 4, upper cover 2 is fixed by 4 set bolts 1 with lower cover 4.
Claims (1)
1. a low pressure casting double-layer seal bell, comprise upper cover and lower cover, upper cover and interval, corresponding section, lower cover edge offer multiple fastening bolt seams uniformly, the center of upper cover and lower cover offers stalk fixing port, it is characterized in that: between described upper cover and lower cover, be folded with heat insulation refractory plate, upper cover and lower cover are fixed by multiple set bolts.
