Description
[technical field]
The utility model relates to the technical field of refractory material, the technology of especially a kind of mineral hot furnace stemming prefabricated component is led
Domain.
[background technique]
Blast furnace taphole is in long-term smelting production, and due to bearing to wash away for a long time and corrode, tapping hole bosh gas index is thinning,
It forms local anomaly to corrode, cupola well water temperature difference, heat flow rate per unit area and temperature are easier to occur higher in normal point near iron mouth, lead to furnace
Cylinder side wall temperatures increase.In order to make iron mouth stable working state, meet the needs of intensification of smelting process in BF, it is desirable that the operation of stemming
Property, volume stability and opening performance to get well, and stemming used by current large and medium-sized blast furnace is not easily accessible clay gun, scum holds
Easily spilling, tapping duration are short, therefore are not able to satisfy the demand that modernization is smelted.
[utility model content]
The purpose of this utility model is exactly to solve the problems of the prior art, proposes a kind of mineral hot furnace stemming prefabricated component,
Stemming prefabricated component can be made to be easier to enter in clay gun, volume stability and opening performance are good, are not easy craze and transfiguration, are conducive to promote
Using.
To achieve the above object, the utility model proposes a kind of mineral hot furnace stemming prefabricated components, including guide post, stemming
The bottom of stemming cylinder is arranged in cylinder and splicing slot, the guide post, and the top of stemming cylinder, institute is arranged in the splicing slot
It states and is axially provided through structure through-hole in stemming cylinder, the structure through-hole runs through guide post and splicing slot, the big gun vertically
Multiple through flow holes are provided on mud column side face, the through flow hole is connected with structure through-hole.
Preferably, the shape of the guide post is cone, the shape of the stemming cylinder is cylinder, the splicing
Slot is cone-shaped groove, and the guide post and splicing slot are corresponding identical up and down.
Preferably, the lateral surface of the guide post is provided with several detent slots, the medial surface correspondence of the splicing slot is set
It is equipped with detent convex block, the detent slot and the corresponding splicing of detent convex block.
Preferably, the through flow hole is uniformly circumferentially positioned on stemming cylinder, the through flow hole is cylindrical hole.
Preferably, the axle center of the guide post, stemming cylinder and splicing slot is located along the same line, the structure through-hole
Through setting on axial line.
The utility model has the beneficial effects that the utility model is by being incorporated in one for guide post, stemming cylinder and splicing slot
It rises, by assay optimization, conical guide post can make stemming prefabricated component be easier to enter in clay gun, structure on stemming cylinder
Through-hole and through flow hole, which are worked in coordination, can guarantee preferable gas permeability, be not easy craze and transfiguration, while filling water when necessary
Mud blockage structure through-hole promotes overall tightness, and guide post and splicing slot splice mutually the combination that can be convenient multiple prefabricated components,
Conducive to installation, stemming prefabricated component can be made to be easier to enter in clay gun, volume stability and opening performance are good, change not easy to crack
Shape is conducive to promote and apply.
The feature and advantage of the utility model will be described in detail by embodiment combination attached drawing.
[Detailed description of the invention]
Fig. 1 is a kind of structural schematic diagram of mineral hot furnace stemming prefabricated component of the utility model.
In figure: 1- guide post, 2- stemming cylinder, 3- splice slot, 4- structure through-hole, 5- through flow hole, 6- detent slot, 7- detent
Convex block.
[specific embodiment]
Refering to fig. 1, a kind of mineral hot furnace of the utility model stemming prefabricated component, including guide post 1, stemming cylinder 2 and splicing
The bottom of stemming cylinder 2 is arranged in slot 3, the guide post 1, and the top of stemming cylinder 2, the big gun is arranged in the splicing slot 3
Structure through-hole 4 is axially provided through in mud cylinder 2, the structure through-hole 4 is vertically through guide post 1 and splicing slot 3, the big gun
Multiple through flow holes 5 are provided on 2 side of mud cylinder, the through flow hole 5 is connected with structure through-hole 4, the shape of the guide post 1
For cone, the shape of the stemming cylinder 2 is cylinder, and the splicing slot 3 is cone-shaped groove, the guide post 1 and spelling
About 3 access slot is corresponding to coincide, and the lateral surface of the guide post 1 is provided with several detent slots 6, the medial surface pair of the splicing slot 3
It should be provided with detent convex block 7, the detent slot 6 and the corresponding splicing of detent convex block 7, the through flow hole 5 are uniformly circumferentially positioned at big gun
On mud cylinder 2, the through flow hole 5 is cylindrical hole, and the axle center of the guide post 1, stemming cylinder 2 and splicing slot 3 is located at same
