Abstract

The utility mode provides a novel blast-furnace crucible which has the advantages of being safe, long in service life and energy-saving. The blast-furnace crucible comprises a carbon brick brasque located outside the crucible, a clay-protecting brick brasque located inside the crucible and a ludox combined corundum carborundum ceramic brasque which is located between the carbon brick brasque and a clay-protecting brick brasque. The blast-furnace crucible protects the carbon brick brasque outside the crucible from weathering. Meanwhile, the corundum carborundum brasque can reduce the loss of heat in the furnace because of low capacity of heat transmission in order to achieve the energy-saving and consumption-reducing effect. The carbon brick brasque outside the crucible can effectively cool the ceramic cup brasque through a blast furnace cooling system because of the good capacity of the heat transmission in order to lower the temperature of the ceramic cup brasque and prolong service life. The carbon brick brasque and the ceramic cup brasque protect and depend on each other to form an organic whole in a seamless joint enabling the blast furnace to be safe, long in service life and energy-saving in production.

Description

A kind of novel blast-furnace cupola well
Technical field
The utility model relates to a kind of cupola well, especially a kind of novel blast-furnace cupola well.
Background technology
The blast furnace hearth liner extensively adopts brick fuel one ceramic cup inner lining structure at present, and wherein ceramic cup is built by laying bricks or stones by fritter corundum brick or bulk corundum prefabricated section and formed.Only have 2~5 years actual service life.A very large defective of existing ceramic cup is: the brickwork joint of the slit between ceramic cup masonry and the brick fuel and ceramic cup masonry itself becomes weak link, and the slag molten iron is invaded the work-ing life of destroying furnace lining and then reducing ceramic cup by these slits.
The utility model content
The utility model provides a kind of safe, long-lived, energy-conservation novel blast-furnace cupola well.
Realize the novel blast-furnace cupola well of the utility model purpose, comprise being positioned at outside carbon block lining, be positioned at inner clay protection tile furnace lining, be cast in the silicasol-combined corundum silicon carbide ceramics cup furnace lining between carbon block lining and the clay protection tile furnace lining.
The beneficial effect of novel blast-furnace cupola well of the present utility model is as follows:
Novel blast-furnace cupola well of the present utility model, through the sintering of blast oven and blowing-in operation initial stage heat, the silicasol-combined corundum silicon carbide castable sinters a densification, seamless monolithic devices furnace lining into.In blast furnace production process, this densification, seamless monolithic lining can effectively prevent the infiltration erosion of the media such as the interior slag molten iron of blast furnace, and the carbon line in the protection outside does not weather; The corundum carborundum monolithic lining can reduce the loss of furnace heat because having the lower capacity of heat transmission simultaneously, thereby reaches energy-saving and cost-reducing effect.The carbon line in the outside can effectively cool off the ceramic cup furnace lining by blast furnace cooling system because having good heat conductivility, reduces the temperature of ceramic cup furnace lining, prolongs its work-ing life.Carbon line and ceramic cup furnace lining give mutual protection, the organic whole of a slitless connection of interdependent formation each other, makes blast furnace realize safety, long-lived, production energy-saving.
Description of drawings
Fig. 1 is the structural representation of novel blast-furnace cupola well of the present utility model.
Embodiment
As shown in Figure 1, novel blast-furnace cupola well of the present utility model comprises being positioned at outside carbon block lining 1, is positioned at inner clay protection tile furnace lining 3, is cast in the silicasol-combined corundum silicon carbide ceramics cup furnace lining 2 between carbon block lining 1 and the clay protection tile furnace lining 3.
During the blast furnace construction, build first the carbon line 1 in the outside by laying bricks or stones, build again the most inboard clay protection tile furnace lining 3 by laying bricks or stones, then cast silicasol-combined corundum silicon carbide castable between carbon line 1 and clay protection tile furnace lining 3; Sintering finally by blast oven and blowing-in operation initial stage heat forms ceramic cup furnace lining 2.
The advantage of novel blast-furnace cupola well of the present utility model is as follows:
1. can close contact between carbon line and the ceramic cup furnace lining, solved the problem of " seam ".
2. the ceramic cup of cast-in-site construction forms a seamless integral body in the stove behind the heat sintering of blast furnace itself, and the overall construction intensity of furnace lining improves greatly.
3. the application of silicasol-combined corundum silicon carbide castable can solve the difficult problem that cement mould material hot strength reduces.
4. easy construction, save energy.
Embodiment recited above is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; design under the spiritual prerequisite not breaking away from the utility model; various distortion and improvement that the common engineering technical personnel in this area make technical solutions of the utility model all should fall in the definite protection domain of claims of the present utility model.

Claims (1)

1. a novel blast-furnace cupola well is characterized in that: comprise being positioned at outside carbon block lining, be positioned at inner clay protection tile furnace lining, be cast in the silicasol-combined corundum silicon carbide ceramics cup furnace lining between carbon block lining and the clay protection tile furnace lining.
