Description
Technical field
The utility model belongs to smelting ferronickel industry, and in particular to a kind of ferronickel small furnace furnace lining structure.
Background technology
The blast furnace of production ferronickel is typically all small blast furnace, and structure is that bosh uses cast-iron cooling wall, is close to cooling wall
Single to build one layer of refractory brick, furnace bosh and restoration of lower stack as the cooling wall with boss and lay bricks, wherein boss plays support brick.Furnace bosh and
With laying bricks for upper bit, supported by the boss with cooling wall.After laying bricks before furnace bosh and restoration of lower stack boss is etched, boss
It is directly contacted with high-temp. furnace material and Gas Flow, molten condition, especially boss will occur in cooling wall boss forward position and corner at this time
There is serious bed separation in corner, therefore is burned quickly.After the boss of cooling wall is burned, the support brick of boss loses branch
Support, then occur local shedding.Lose support bricking will occurrence of large-area come off, the cooling wall for losing bricking protection exists
It is burned out at a high temperature of 1300 DEG C~900 DEG C.The shortcomings that this structure is that there are cooling blind areas for cast-iron cooling wall, and cooling effect is not
Good, bricking is easily etched, and after the boss of especially cooling wall is burned, loses supporting role, furnace wall is caused to cave in, should
The lining durability of structure is shorter.
Utility model content
The utility model in order to solve cooling wall structure insufficient existing for ferronickel blast furnace, a kind of intensity of cooling is provided
Ferronickel small furnace furnace lining structure high, support effect is good.
The purpose of this utility model is realized in the following manner：A kind of ferronickel small furnace furnace lining structure, including stove skin and
The setting of stove intradermal side is laid bricks, and stove skin and sets the castable poured between laying bricks, and described lay bricks is divided into long brick and short brick,
Long brick and short brick are arranged alternately, and castable is cast between long brick and short brick and stove skin；Stove skin and setting cooling dress between laying bricks
It puts, cooling device is fixed on stove skin.
Cooling device includes thick-wall seamless, and thick-wall seamless is U-shaped, and it is opposite that thick-wall seamless both ends port is pierced by stove skin
On the outside of stove skin, thick-wall seamless water flowing cooling.
Cooling device sets the U-shaped thick-wall seamless of at least three from top to bottom.
Cooling device includes the anchoring heat conduction being fixed on stove skin nail, spray equipment is set to spray stove skin outside stove skin.
Castable is C-SiC-AL castables.
The beneficial effects of the utility model are：To furnace body cooling and brick construction be optimized, keep bosh, furnace bosh and
There is appropriate intensity of cooling in restoration of lower stack region, and does liner using the strong refractory material of antiscour erosiveness, is producing
The rational operation type of furnace can be formed in journey and the type of furnace is kept to stablize, extends the service life of furnace lining, so as to reach furnace condition anterograde,
Production is stablized, energy-saving target.
Description of the drawings
Fig. 1 is 1 principle schematic diagram of the utility model embodiment.
Fig. 2 is 2 principle schematic diagram of the utility model embodiment.
Wherein, 1 is stove skin, and 2 be castable, and 3 is lay bricks, and 4 be thick-wall seamless, and 5 be anchoring heat conduction nail.
Specific embodiment
Embodiment 1
As shown in Figure 1, a kind of ferronickel small furnace furnace lining structure, 2 He of castable set including stove skin 1 and 1 inside of stove skin
Lay bricks 3.Stove skin 1 and the castable 2 for setting between 3 and pouring of laying bricks.3 points are laid bricks as long brick and short brick, long brick and short brick are handed over
For setting, castable 2 is cast between long brick and short brick and stove skin 1；It stove skin 1 and lays bricks cooling device is set between 3, cooling dress
It puts and is fixed on 1 inner wall of stove skin.Cooling device includes thick-wall seamless 4, and thick-wall seamless 4 is U-shaped, 4 both ends of thick-wall seamless
Port is pierced by stove skin 1 against 1 outside of stove skin, 4 water flowing of thick-wall seamless cooling.The cooling device of the utility model is set from top to bottom
Put multiple U-shaped thick-wall seamless 4.Castable is C-SiC-AL castables.C-SiC-AL castables under the high temperature conditions intensity compared with
Height, thermal conductivity are good, refractory dreg chemistry corrodes.Seamless pipe water flowing postcooling C-SIC-Al matter castables, plays cast-iron cooling wall
Effect.
Embodiment 2
As shown in Fig. 2, the embodiment 2 of the utility model is with embodiment 1, the difference lies in the differences of cooling device, real
It applies the cooling device in example 2 and includes the anchoring heat conduction being welded on stove skin 1 nail 5, spray equipment is set to spray stove skin 1 outside stove skin 1.
It is good to anchor heat conduction 5 thermal conductivity of nail, can realize heat exchange, reduce blast furnace lining temperature.The spray cooperation anchoring heat conduction of stove skin 1 nail 5
Strengthen furnace lining cooling, the intensity of cooling of cooling wall is much larger than by calculating its intensity of cooling.
The utility model lays bricks 3 using the fixation of castable 2, stove skin 1 and lays bricks and sets cooling device, cooling device between 3
Can be that 4 water flowing of thick-wall seamless cools down, or the good anchoring heat conduction nail 5 of heat conductivility, stove skin 1 are fixed in stove skin 1
Outer spraying cooling, by anchoring 5 conduction heat of heat conduction nail.This cooling device and pouring material 2 fix lay bricks 3 structure, prevent
The drawbacks of cooling wall boss brick hold structure；It is all eaten away even if laying bricks, thick-wall seamless 4 and anchoring heat conduction nail 5 are directly
It is contacted with furnace charge and Gas Flow, since the intensity of cooling of the two is higher than cast-iron cooling wall, also easily quickly forms " slag crust " protection
Layer.Slag crust protective layer and the binding ability of castable 2 are strong, not easily to fall off, and refractory lining can uniform erosion, more have
Conducive to the stabilization and furnace condition anterograde for keeping the operation type of furnace.Therefore, the service life of furnace lining can be greatly prolonged, and reduces construction
Investment.
