Abstract
A kind of electric smelting method production white fused alumina dumping furnace, including furnace body, the furnace body set 8 layers, respectively white fused alumina layer, corundum pouring layer, hollow sphere pouring layer, high aluminium brick layer, fiber blanket layer, layers of nanofibers, insulating layer and outer steel shell layer altogether from the inside to the outside.Dumping furnace provided by the utility model, furnace body innermost layer use white fused alumina layer, and the part for having good heat resistance and intensity, and contacting with melting liquid occurs fusing and also has no adverse effects to the quality of final products white fused alumina；In addition corundum pouring layer, the hollow sphere pouring layer used all has higher intensity and heat resistance, and thermal insulation material additionally uses layers of nanofibers in addition to fiber blanket layer, has better thermal insulation property；Therefore, dumping furnace provided by the utility model good can meet needed for electric smelting method production white fused alumina.
Description
Technical field
The utility model belongs to white fused alumina production equipment technology, and in particular to a kind of electric smelting method production white fused alumina is with inclining
Furnace.
Background technique
White fused alumina production at present is completed using dumping furnace, mainly by the way that bauxite or alumdum etc. are added into dumping furnace
Then by insertion heated by electrodes melting reaction occurs at high temperature for raw material, after reaction, by by tilting furnace, by furnace
Interior high-temperature fusant, which pours into, to be connect in packet, and white fused alumina product is obtained.It is existing to topple over furnace body generally by high temperature oxidation resisting aluminium layer, graphite
Layer, mullite layer, ceramic fibre blanket layer, outer furnace wall layer composition, the white fused alumina as disclosed in patent CN201620483204.X are smelted
Furnace, but white fused alumina is smelted and needs to have the thermal stability of furnace body, chemical stability, shock resistance etc. at 2000 degree or more
Very high requirement, it is higher especially for furnace body innermost layer material requirements, if in smelting process inner layer material melt into
Enter in melting liquid, will affect white fused alumina quality；Existing furnace body performance is not able to satisfy the demand.
Utility model content
The purpose of this utility model is that solve the deficiencies in the prior art and provides a kind of electric smelting method production white fused alumina
Use dumping furnace.
The purpose of this utility model is realized with following technical proposals:
A kind of electric smelting method production white fused alumina dumping furnace, including furnace body, the furnace body set 8 layers altogether from the inside to the outside, respectively
White fused alumina layer, corundum pouring layer, hollow sphere pouring layer, high aluminium brick layer, fiber blanket layer, layers of nanofibers, insulating layer and outer steel shell
Layer.
Cool water shower system is set on the outer steel shell.
The cool water shower system includes the sparge pipe and temperature sensor being arranged on outer steel shell.
The hollow sphere pouring layer is alumina hollow ball pouring layer.
The high aluminium brick layer is light weight alumina brick layer.
The fiber blanket layer is ceramic fibre blanket layer.
The layers of nanofibers is aeroge nano heat-insulating fibrous layer.
The insulating layer is rock wool heat-preservation layer.
Dumping furnace provided by the utility model, furnace body innermost layer use white fused alumina layer, have good heat resistance and intensity,
And the part contacted with melting liquid occurs fusing and also has no adverse effects to the quality of final products white fused alumina；In addition it uses
Corundum pouring layer, hollow sphere pouring layer all have higher intensity and heat resistance, and thermal insulation material is also used in addition to fiber blanket layer
Layers of nanofibers has better thermal insulation property；Therefore, dumping furnace provided by the utility model good can meet electric smelting method
It produces needed for white fused alumina.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Electric smelting method provided by the utility model produces white fused alumina dumping furnace, as shown in Figure 1, including furnace body, furnace body is by interior
Set 8 layers altogether to outer, respectively white fused alumina layer 1, corundum pouring layer 2, hollow sphere pouring layer 3, high aluminium brick layer 4, fiber blanket layer 5, receive
Rice fibrous layer 6, insulating layer 7 and outer steel shell layer 8.Wherein, white fused alumina (alumina content is greater than 99%) layer is located at furnace body innermost layer,
It is directly contacted with melting liquid；Corundum (alumina content is greater than 90%) pouring layer has mechanical strength more higher than mullite layer
And anti-erosion performance；Hollow sphere pouring layer preferably uses alumina hollow ball pouring layer, and high temperature resistant, intensity are high, can reduce simultaneously
Furnace body weight, convenient for toppling over；High-alumina brick (alumina content is greater than 48%) layer is preferably light weight alumina brick layer, equally with excellent
It also can reduce furnace body weight while benign energy；Fiber blanket layer is preferably ceramic fibre blanket layer, and layers of nanofibers is preferably airsetting
Glue nano heat-insulating fibrous layer, thermal insulation property are 4 times of ceramic fibre blanket layer or so, and the insulating layer on the outside of layers of nanofibers can be selected
The common flame-proof thermal insulation material such as rock wool, outermost outer steel shell mainly play a supportive role, and cooling water spray is preferably set on outer steel shell
Leaching system, cool water shower system may include the sparge pipe 9 and temperature sensor being arranged on outer steel shell, when detecting shell temperature
Degree can carry out water-spraying control automatically, prevent furnace body from overheating, influence service life more than 150 degree.
