Description
Technical field
The utility model is related to a kind of wall body structure more particularly to a kind of electrical heating shaft furnace are compound with soaking zone wear resistant heat preserving
Wall belongs to kiln building technology field.
Background technology
China lists ten big energy-saving and emission-reduction key projects in " 12 planning ", wherein what is be firstly mentioned is exactly industry
Boiler (kiln) improvement project, positive promotion and implementation Industrial Boiler (kiln) reducing energy consumption engineering are imperative.Electrical heating shaft furnace
Not only with clean energy resource, and fuel combustion is not needed, the exhaust gas dust of discharge is few, is gradually praised highly by industrial factories and miness.
Soaking zone is the main heating region of shaft furnace, and by taking magnesite clinker as an example, light roasting temperature is 850 DEG C, and in soaking zone, material washes away
Speed is 0.5 m/min.However electrical heating shaft furnace soaking zone kiln wall uses the resistance to material of single structure, such as uses light-weight mullite
Brick does inner lining material, then anti-material scouring capability is poor, with needing to repair after certain heat, influences production efficiency；Such as use corundum
Matter castable does liner, then heat insulation effect is poor, and kiln wall temperature outside is higher than 150 DEG C, and heat loss is big in kiln, has both influenced product matter
Amount, also increases production cost.
Utility model content
For the above technical problem, provided by the utility model is that a kind of electrical heating shaft furnace soaking zone wear resistant heat preserving is compound
Wall is, and it is an object of the present invention to provide a kind of liner wall that resistance to material washes away, can and under the premise of providing identical electric energy heating
More thermal energy are more effectively utilized, scattering and disappearing for electrical heating shaft furnace internal heat is reduced, reduces production cost.
The utility model is achieved through the following technical solutions：A kind of electrical heating shaft furnace soaking zone wear resistant heat preserving composite wall
Body, which is characterized in that by including successively to outside inside shaft furnace：Zircon corundum brick wearing layer, high alumina castable permanent layer, foam water
The first insulating layer of adobe and high the second insulating layer of aluminum wool plate.
Wearing layer plays anti-material souring with zircon corundum brick；Permanent layer with high alumina castable have thermal coefficient it is low,
Heat preservation and insulation is good, linear shrinkage is small, cast good integrity, the features such as dry tenacity is high；First insulating layer foamed cement
The effect of brick is prevented from kiln internal heat to external diffusion；The second external insulating layer can be to greatest extent using high aluminum wool plate
Prevent heat loss.Wear resistant heat preserving composite wall body structure described in the utility model is simple, heat preservation and wearability are good, uses the longevity
Life length can effectively prevent scattering and disappearing for heat, make the equal thermal process stable operation of electrical heating shaft furnace.
The utility model has the beneficial effects that：
1. kiln interior wall uses wearing layer and permanent layer double-layer structure, the service life of liner can be improved, saves repair
Cost.
2. insulating layer uses foam water adobe and high aluminum wool plate composite construction, make electrical heating shaft furnace kiln wall heat insulation and preservation effect
It greatly improves, more thermal energy can be effectively converted under the premise of identical electric energy, and then reduce production cost.
3. heat is lost in reduction kiln, it can ensure that product quality, kiln external enwergy reduce wall temperature in kiln.
Description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is a kind of electrical heating shaft furnace of the utility model soaking zone wear resistant heat preserving combined wall schematic diagram.
In figure：1 zircon corundum brick wearing layer, 2 high alumina castable permanent layers, 3 the first insulating layers of foam water adobe, 4 high aluminum wools
The second insulating layer of plate.
Specific implementation mode
Specific embodiment of the present utility model is illustrated below in conjunction with the accompanying drawings.The utility model is a kind of electrical heating
Shaft furnace soaking zone wear resistant heat preserving combined wall.By including successively to outside inside shaft furnace：Wearing layer, permanent layer, the first heat preservation
Layer and the second insulating layer.Wearing layer 1 is built by laying bricks or stones using zircon corundum brick, since its excellent thermal shock resistance and wearability can improve
The wearability of kiln wall.Permanent layer 2 is formed using high alumina castable one-piece casting, is first built wearing layer 1 in work progress by laying bricks or stones and is built by laying bricks or stones again
First insulating layer 3, finally pours into high alumina castable in being spaced to the two.The material of first insulating layer 3 is foam water adobe, can
Further to prevent heat to external diffusion.The material of second insulating layer 4 is high aluminum wool plate, is located at the outside of foam water adobe, high
The thermal coefficient of aluminum wool plate can prevent scattering and disappearing for heat to the greatest extent well below the thermal coefficient of brick body.This practicality is new
Type wall is successively constructed as requested, it is ensured that and it is easy for construction, so that the wear resistant heat preserving performance of electrical heating shaft furnace wall is strengthened, subtracts
Scattering and disappearing for few shaft furnace internal heat, ensure that the quality of sinter, reduce production cost.
Embodiment 1
It builds wearing layer in work progress by laying bricks or stones first, selects Corhart Zac-block as lining brick, then use foamed cement brick
The first insulating layer is built, wearing layer and the first insulating layer are carried out grouting as the inner and outer template of permanent layer castable to be poured, permanently
It is 75% High-Alumina Low Cement Castable that layer pouring material, which selects aluminium content, finally installs high alumina containing zirconium in the outside of foamed cement
Matter ceramic fiber cotton plate (1300 DEG C of temperature in use).
Kiln wall after being constructed according to the present embodiment in use stablize by product quality, wear-resisting after 50 sintering
For layer without apparent deterioration, shaft furnace exterior wall temperature is 40 DEG C.
Embodiment 2
It builds wearing layer in work progress by laying bricks or stones first, selects sintering zircon corundum brick as lining brick, then use foamed cement brick
The first insulating layer is built, wearing layer and the first insulating layer are carried out grouting as the inner and outer template of permanent layer castable to be poured, permanently
It is 75% High-Alumina Low Cement Castable that layer pouring material, which selects aluminium content, and finally in the outside of foamed cement, installation contains conventional aluminium
Matter ceramic fiber cotton plate (1000 DEG C of temperature in use).
