The length and the spacing between front furnace wall and rear furnace wall of left furnace wall and right furnace wall is can adjust in experiment, while adjusting
The spacing of whole left furnace wall and right furnace wall and change the convex shape plate of different length to adjust the width and length of furnace wall, so that real
Stove is tested suitable for various sizes of cooling wall.
Front furnace wall and rear furnace wall are provided with equidistant three rows through hole, often arrange two through holes of arbitrary neighborhood in through hole
The distance between it is also equal；Heat-generating pipe group is made up of many siliconits, and siliconits are all in the through hole of furnace wall.
Used by test, cooling wall is blast-furnace bosh area cooling wall, and installation screwed hole, thermocouple are provided with cooling wall
Hole.
Cooling wall is sling and forms burner hearth with furnace wall by bearing support.
There is following good effect compared with prior art due to adopting above-mentioned technical proposal, this utility model：
One is to replace existing burning diesel oil heating, heating-up temperature to be easily controlled using siliconits electrified regulation, hot examination
Test result more accurate；Two are switched on heating eliminates burner and combustor, saves floor space and experimental cost, while more
Plus safety and environmental protection；Three is to make cooling wall accumbency on furnace wall, reduces the height of experimental furnace, makes test operation easier；Four
It is that experimental furnace goes for various sizes of cooling wall.
Description of the drawings
Fig. 1 is a kind of structural representation of the present utility model；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the side view of Fig. 1.
Specific embodiment
In conjunction with the drawings and specific embodiments, the utility model is described in further detail, not in its protection domain
Limit.
A kind of blast furnace cooling stave Thermal-state test stove, by furnace bottom (1), furnace wall (2), heat-generating pipe group (3), cooling wall (4), edge brick
(5), bearing support (6) composition, furnace bottom (1) are made up of the refractory brick for being laid in ground, and furnace wall (2) are by front furnace wall (8), rear furnace wall
(9), the combination type furnace wall that left furnace wall (10), right furnace wall (11) are constituted, front furnace wall (8) and rear furnace wall (9) are fixed on furnace bottom (1)
On, and be made up of left plate (12), (14) three pieces of precoated plates of electroplax (13) and right panel respectively, wherein middle plate (13) for convex shape plate simultaneously
Respectively use plate, left plate (12) and the right panel (14) for having polylith different length is spliced into one block of smooth plate, left furnace wall with middle plate (13)
(10) and right furnace wall (11) is the furnace wall being built into refractory brick on furnace bottom (1), heat-generating pipe group (3) is through in front and back's front and rear side stove
Wall, cooling wall (4) by bolt (7) on bearing support (6) and with furnace wall (2) formed burner hearth；It is provided with cooling wall
Screwed hole, thermocouple mounting hole.
First guaranteed that, in experimental furnace Land leveling, furnace bottom (1) was in ground grading volume before cooling wall experimental furnace is built
Density is that 1.0 mullite light fire brick is built into, and thickness is 200mm, and length is 4600mm, and width is the furnace bottom of 2600mm.
It is 300mm that thickness is built in the mullite light fire brick that the specified location bulk density of furnace bottom (1) is 1.0,
Highly it is left furnace wall (10) and the right furnace wall (11) of 550mm.
Castable refractory is poured into a mould and is anchored on the steel plate of front and rear side, material feeding to be poured be connected as a single entity with steel plate make it is prefabricated
Plate, the specified location that precoated plate is hoisted to furnace bottom is combined to form furnace wall (2).
Before experimental furnace work, first cooling wall (4) is connected with bearing support (6) with bolt, then will by handling apparatus
The bearing support (6) being connected with cooling wall (4) is hoisted to specified location, makes cooling wall cover the top surface of body of heater.
Front furnace wall (8) and rear furnace wall (9) are provided with equidistant three rows through hole, often arrange arbitrary neighborhood two in through hole
The distance between through hole is also equal；Heat-generating pipe group (3) is made up of many siliconits, and siliconits are all installed in furnace wall (2)
In through hole.
The gap between furnace bottom (1), furnace wall (2), heat-generating pipe group (3), cooling wall (4) is filled up with refractory fiber cotton, make guarantor
Temp effect is more preferable.Connecting test device, cooling wall intake-outlet device, circuit arrangement, you can begin to cool down wall hot test.
This specific embodiment has following good effect compared with prior art：One is that cooling wall lies low in experimental furnace
The height of experimental furnace on furnace wall, is reduced, is easy to experimental implementation.Two is that, using heat-generating pipe electrified regulation, in-furnace temperature is controlled more
Plus it is stable, be conducive to Thermal-state test regulation and control, result accurate.Three are heated using heat-generating pipe, are saved the combustor of combustion heating, are made
Experiment floor space is little, safer.Four is that the periphery of stove has refractory material to be incubated, heat scatter and disappear it is little, it is more energy efficient.
Therefore there is this utility model experimental temperature accurately can control, experimental furnace is easy to operate, safety and environmental protection the characteristics of.
