Abstract
The utility model discloses a novel granulated slag chute which is characterized in that cooling pipe sets are mounted at the front outflow end of the bottom of the slag chute, and the middles and the upper parts of the cooling pipe sets are filled and covered with refractory materials. Compared with the prior art, the defect of frequent cracking of a conventional chute can be effectively overcome, the service life is prolonged, and the cost is reduced.
Description
Technical field
The utility model relates to a kind of granulation slag runner chute, is specially the novel granulation slag runner chute with cooling tube.
Background technology
Granulation slag runner chute is after molten iron is processed, when molten iron is poured out, and need to the flow direction of molten iron be led for granulation slag runner chute, and existing granulation slag runner chute is all whole casting structure.
When toppling over molten iron, especially when molten iron flows out, because of tall and big more than 1000 degree of temperature of molten iron, like this, often occur that granulation slag runner chute bottom land front end outflow end blows the phenomenon of fracture,
Occur that after breach phenomenon, existing solution can only be the granulation slag runner chute more renewing, and the granulation slag runner chute more renewing one side chute cost taken by themselves is very high, meanwhile, needs to stop production in Renewal process, causes economic loss; Because of excess Temperature, replacing need to wait to be cooled on the other hand, changes required time long, wastes time and energy.
Summary of the invention
The shortcoming existing in order to solve existing chute, the utility model provides a kind of novel granulation slag runner chute, can effectively solve the often deficiency of cracking of existing chute, thus the object that reaches long service life, reduces costs.
For achieving the above object, the utility model is achieved through the following technical solutions:
A novel granulation slag runner chute, comprises chute body, and the both sides of chute body are ledge, and middle part is the bottom land of flowing through for molten iron that is connected to ledge bottom, and at least the bottom land of chute body is provided with cooling system.
Further, described cooling system is at least positioned at the anterior outflow end of bottom land.
Further, described cooling system is the cooling tube group being set up in parallel, and the duct orientation of cooling tube group is parallel with molten iron circulating direction.
Further, cooling system is the cooling tube group being set up in parallel, and the duct orientation of cooling tube group is vertical with molten iron circulating direction.
Further, between described cooling tube group, be filled with refractory material; The top of cooling tube group is coated with refractory material.
Further, the upper surface of described refractory material is higher than granulation slag runner chute bottom land end face.
Further, the ledge of granulation slag runner chute is stretched out at the two ends of described cooling tube group.
Further, the plane at described cooling tube group place and the bottom land place plane parallel of granulation slag runner chute.
Operation principle of the present utility model and beneficial effect are embodied in:
The utility model, on granulation slag runner chute, especially arranges cooling system, like this on bottom land; the high temperature liquid iron of flowing through can obtain the cooling of cooling system; effectively reduce granulation slag runner chute bottom land be subject to Wen Wendu, thereby effectively protected bottom land, there will not be the phenomenon of cracking.
Further, cooling system is arranged on to the front end of bottom land, the top ftractureing, there is not the phenomenon of cracking in top like this, thus whole bottom land all there will not be the phenomenon of cracking.
Cooling system adopts the version of cooling tube group arranged side by side, simple in structure, good cooling results, and meanwhile, cooling tube group can be according to the temperature of molten iron, and it is vertical or arranged side by side selecting the direction of flowing through with molten iron.
Between cooling tube group and above cooling tube group, refractory material is being set, on the one hand, refractory material is protected cooling tube group, prevents its excess Temperature, and the water boiling pressure in pipe group becomes the large danger that produces; On the other hand, the existence of refractory material can excessively not lowered the temperature molten iron yet, has guaranteed the mobility of molten iron.
To sum up, by arranging after cooling system, the life-span of novel granulation slag runner chute greatly extends, and by changing one to twice original January, just changing once more than a year till now, has improved production efficiency, guaranteed the safety that molten iron is toppled over.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, the accompanying drawing the following describes is only some embodiment that record in the application, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing;
Fig. 1 is the structural representation of granulation slag runner chute;
Fig. 2 is the structural representation of granulation slag runner chute.
The specific embodiment
The content of not addressing below all can be by prior art.
In order to make those skilled in the art person understand better the technical scheme in the application, below in conjunction with the accompanying drawing in the embodiment of the present application, technical scheme in the embodiment of the present application is clearly and completely described, obviously, described embodiment is only the application's part embodiment, rather than whole embodiment.Embodiment based in the application, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the application's protection.
As shown in Figure 1-2, a kind of novel granulation slag runner chute, comprises chute body 1, and the both sides of chute body 1 are ledge 2, and middle part is the bottom land 3 of flowing through for molten iron that is connected to ledge bottom.
The anterior outflow end of the bottom land 3 of chute body 1 is provided with cooling system; Can certainly expand the coverage of cooling system, such as the inwall of the even whole chute body 1 in whole region of bottom land 3.
The cooling system of the present embodiment is the cooling tube group 4 being set up in parallel, the duct orientation of cooling tube group 4 or vertical even angle of inclination parallel with molten iron circulating direction, and the present embodiment adopts vertical scheme.
Refractory material is filled or is coated with between the cooling tube group 4 of the present embodiment and the top of cooling tube group, by cooling tube group and molten iron isolation, cooling tube group is not directly contacted with molten iron.
The cooling system of this enforcement can improve on the basis of existing granulation slag runner groove; punched in the position that is positioned at bottom land front portion of two ledges; in the hole on both sides, wear cooling tube; and weld with ledge; for guaranteeing cooling uniformity; each cooling tube is parallel to each other, and parallel with bottom land end face, then in pipe group, covers filling fire resisting material.
The above is only a kind of in the utility model embodiment, but protection domain of the present utility model is not limited in this.Any variation of expecting without creative work and replacement, all should belong to protection domain of the present utility model.Therefore protection domain of the present utility model should be as the criterion with claims limited range.
