Description
Technical field
The utility model belongs to blast furnace field more particularly to a kind of blast furnace residue channel prefabricated section in ironmaking.
Background technique
With the reinforcing of blast furnace enlargement and smelting, slag iron amount increases, and slag iron temperature improves, and slag runner refractory material makes
It is increasingly severe with environment.Especially public slag runner, due to by high-temperature slag long-time, uninterruptedly wash away, damage faster, need to adopt
Slag runner is poured again in time with blast furnace residue channel castable.
In addition, the construction of slag runner castable using vibration with the method that combines is smeared, i.e., first with vibrating head by slag
Then the jolt ramming of ditch bottom carries out smearing construction to side wall.Therefore, castable used must have suitable flow behavior: existing
Good mobility to guarantee that bottom is closely knit, but cannot have self drainage again, and otherwise side wall can not be smeared.
It constructs total time-consuming about 3.5 hours in addition, pouring slag runner, the natural curing time at least 2 hours, with small after the completion of construction
Fire baking 24 hours, is then respectively toasted 6 hours with moderate heat and high fire, can just be come into operation.
In addition, especially in the slag convolution region apart from 3~5 meters of sow, slag runner lining is invaded in slag runner use process
Erosion is big, is easy to burn, need to continually carry out hot repair.
In addition, sometimes for racing against time, slag runner refractory material, which does not parch, is just eager using causing part to blow out, in slag runner
Serve as a contrast it is thinning, such as repair not in time, or even burn slag runner, seriously affect blast furnace and normally produce.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of blast furnace residue channel prefabricated section, leading prefabricated storage,
Use is direct plungeed into when needing, eliminate pour, conserve, baking time, solve in the prior art, slag runner is locally blown out, slag
Ditch liner is thinning, need to continually carry out hot repair, or even burn slag runner, seriously affect the problems such as blast furnace normally produces.
The utility model is realized in this way providing a kind of blast furnace residue channel prefabricated section, including prefabricated block body, prefabricated section sheet
Perforation is equipped with isosceles trapezoid groove on body length direction, symmetrically sets hoisting ring, and prefabricated section on the prefabricated block body of groove two sides
Body interior sets reinforcing bar keel.
Further, the prefabricated block body periphery is rectangular parallelepiped structure.
Further, the hoisting ring is equipped with 4, sets two respectively on the prefabricated block body of the groove two sides.
Further, the hoisting ring is fixed on the intrinsic part of the prefabricated section and the fixed company of the reinforcing bar keel
It connects.
Further, the prefabricated Block body length is 2000mm；Width is 1200mm；Height is 760mm；The groove
Depth is 420mm.
Compared with the prior art, the advantages of the utility model are:
1, easy to make, labor intensity is low；Elevated temperature strength is big, resistance to erosion, and anti-erosion is anti-oxidant；Good thermal shock is not shelled
It falls and cracks, it can quick baking.
2, due to there is time enough natural curing, prefabricated section consistency is higher, good permeability, is not easy to send out in use process
Life is burst.
3, replace when save pour, conserve, baking time, facilitate quality control, energy conservation and environmental protection, can extend slag runner integrally makes
With service life, save the cost.
4, can be with section displacing, it is convenient to lift, and manually passes through the original-parties such as pneumatic pick, sledgehammer, drill rod when avoiding hot repair
Method manual cleaning warm sludge ditch, cross-operation increase the safety coefficient of hot repair process.
5, the consumption for reducing refractory material, avoids slag runner from burning, and is the stable smooth operation and economic benefit of blast fumance
It improves, provides guarantee.
Detailed description of the invention
With reference to the accompanying drawing and embodiment is described in further detail the utility model:
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model keel positional structure schematic diagram；
Fig. 3 is the utility model schematic view of the front view；
Fig. 4 is the utility model side structure schematic view.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to the accompanying drawing and implement
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is used only for explaining
The utility model is not used to limit the utility model.
With reference to Fig. 1 and Fig. 2, the utility model provides a kind of blast furnace residue channel prefabricated section, including prefabricated block body 1, by
Al2O3, SiC, C and a small amount of cement, using mold vibration pouring molding, perforation is equipped with isosceles ladder on prefabricated 1 length direction of block body
Connected in star, isosceles trapezoid groove are slag channel, symmetrically set hoisting ring 2, and prefabricated section sheet on the prefabricated block body 1 of groove two sides
Reinforcing bar keel 3 are set inside body 1.
Slag runner crosses the quantity of slag generally after 9~100,000 tons, needs replacing slag runner prefabricated section, first old slag runner prefabricated section from
Slag runner slot is successively hung out, then cleaning slag runner slot residue successively hangs in new slag runner prefabricated section in slag runner slot, joins end to end,
Each slag runner prefabricated section joining place claps upper quartz sand, that is, can be used.
Slag runner prefabricated section must be prefabricated in advance, after parching completely, is stored at dry and ventilated, in transport, hoisting process
It cannot collide with other objects, avoid lacking side, fall stubble, or even cannot use.
For beautiful and reduction occupied space, as the improvement of technical solution, prefabricated 1 periphery of block body is cuboid
Structure.
Weight is sling in order to share, as the improvement of technical solution, the hoisting ring 2 is equipped with 4, the groove two sides
Two are set respectively on prefabricated block body 1.
In order to reinforce the bonding strength of hoisting ring 2, as the improvement of technical solution, the hoisting ring 2 is fixed on described pre-
Part in clamp dog ontology 1 is fixedly connected with the reinforcing bar keel 3.
Preferably, 1 length of prefabricated block body is 2000mm；Width is 1200mm；Height is 760mm；It is described
