Abstract
The utility model provides a blast-furnace tapping channel. The blast-furnace tapping channel comprises a channel body and a groove, wherein the groove is formed in the channel body, the upper ends of the two side faces of the channel body are respectively provided with a flange which is protruded outwards, and the channel body is made of a magnesite-chrome refractory material through prefabrication. By using the blast-furnace tapping channel provided by the utility model, both the service life of the blast-furnace tapping channel can be prolonged, and the iron loss in the process of tapping can be reduced; and the blast-furnace tapping channel is easy to mount and stable, and the furnace-front working strength is reduced.
Description
Technical field
The utility model relates to field of metallurgy, more particularly, relates to a kind of discharge equipment of blast furnace slag iron.
Background technology
Blast furnace is in the process of tapping a blast furnace, and high temperature liquid iron and slag flow out from blast furnace taphole, enter casting house.At present, the blast furnace iron outlet groove of industrial application generally adopts brown corundum, alumina, magnesium-aluminium-refractory materialss such as material such as carbon to make, and it all exists sticking iron, dry slag and flimsy shortcoming to some extent, and work-ing life is short, frequency of maintenance is high, affects blast furnace production efficiency.
The utility model content
For the deficiencies in the prior art, one of the purpose of this utility model is to solve the one or more problems that exist in above-mentioned prior art.
For example, one of the purpose of this utility model is to provide a kind of blast furnace iron outlet groove that can improve casting house work-ing life, reduce iron loss and be convenient to install.
To achieve these goals, the utility model provides a kind of blast furnace iron outlet groove.Described casting house comprises ditch body and the groove that is formed on described ditch body, and the upper end of two sides of described ditch body is respectively arranged with outwardly directed flange, and described ditch body forms by the magnesium chrome refractory is prefabricated.
According to an embodiment of blast furnace iron outlet groove of the present utility model, the tapering of two sides of described ditch body can be zero.
According to an embodiment of blast furnace iron outlet groove of the present utility model, the furrow bank of described groove can be cambered surface.
Compared with prior art, the beneficial effects of the utility model comprise: can improve the work-ing life of blast furnace iron outlet groove and reduce iron loss, and easy for installation, stable, reduced the stokehold working strength.
Description of drawings
By the description of carrying out below in conjunction with accompanying drawing, above and other purpose of the present utility model and characteristics will become apparent, wherein:
Fig. 1 shows the section structure schematic diagram of blast furnace iron outlet groove in prior art.
Fig. 2 shows the section structure schematic diagram according to an exemplary embodiment of blast furnace iron outlet groove of the present utility model.
Description of reference numerals is as follows:
1, ditch body (working lining) 2, flange.
Embodiment
Hereinafter, describe blast furnace iron outlet groove of the present utility model in detail in connection with exemplary embodiment.
Fig. 1 is the section structure schematic diagram of blast furnace iron outlet groove in prior art.As shown in Figure 1, the brown corundum of general employing of the working lining 1 of casting house, alumina, magnesium-aluminium-refractory materialss such as material such as carbon are made, and the two sides of working lining have certain taper, the structure that namely employing top is large on cross section, the bottom is little.Building by laying bricks or stones when laying casting house basic, be prone to constructional difficulties, build the problems such as the basis is unstable by laying bricks or stones, dry slag iron phenomenon in use easily occurs, and work-ing life is being short.
Fig. 2 is the section structure schematic diagram according to an exemplary embodiment of blast furnace iron outlet groove of the present utility model.As shown in Figure 2, comprise that according to the blast furnace iron outlet groove of the present embodiment the working lining 1 that directly contacts with slag iron (may also be referred to as and is the ditch body, be formed with passage or the groove crossed for the slag Tie Tong on this ditch body), the upper end of two sides of described working lining 1 is respectively equipped with outward extending flange 2, and working lining 1 forms by the magnesium chrome refractory is prefabricated.Blast furnace iron outlet groove of the present utility model can integral manufacturing, on-the-spotly directly hangs installation with driving a vehicle and can come into operation using.The upper end of two sides of working lining 1 is respectively equipped with outward extending flange 2, is conducive to laying and stablizing of casting house.And adopt the magnesium chrome refractory to make working lining, have the advantages such as good hot strength, resistance to fouling due to the magnesium chrome refractory, improved the anti-slag iron erosional competency of working lining, extended the work-ing life of casting house, and reduced dry slag iron phenomenon, improve iron influx, reduced stokehold labour intensity.
Further, the tapering of two sides of working lining 1 is zero, than band taper design of the prior art, makes the basis of laying casting house build by laying bricks or stones convenient and stable.
The working lining inner-wall surface shape of blast furnace iron outlet groove of the present utility model (namely, the furrow bank of groove) can not limit, as long as form the passage of crossing for the slag flowing molten iron, for example, the furrow bank of groove can be the combination of plane, cambered surface or plane and cambered surface, in the present embodiment, preferably, the inner-wall surface of working lining is cambered surface, forms the groove of the semicircle bodily form, and the smoothness that is conducive to slag iron is passed through.In addition, can carry out specific design according to blast furnace size and need of production according to its concrete size of blast furnace iron outlet groove and the structure of the present embodiment.
In sum, adopt the utility model not only can improve the work-ing life of blast furnace iron outlet groove and reduced iron loss in the process of tapping a blast furnace, easy for installation, stable, reduced the stokehold working strength.
Although the above is by having described the utility model in conjunction with exemplary embodiment, but those skilled in the art should be clear, in the situation that do not break away from the spirit and scope that claim limits, can carry out various modifications and change to exemplary embodiment of the present utility model.
