Abstract
The utility model discloses a flexible gun-top for the closure in front of the blast furnace, which is connected on a hydraulic clay gun. The utility model comprises a gun nozzle which is of barrel structure and one end is connected on the hydraulic clay gun; a steel ring which is connected on the gun nozzle and one side is opened with a groove along the circumference; a shim block which forms a heaved structure on one side and is beset in the groove of the steel ring; a pressure ring which is pressed on the shim block in the groove of the steel ring. By using the convex shim block and the steel ring with groove by the utility model, the convex shim block and a carbon asbestos fibre ring are fixed in the steel ring with groove in inset type, which can obviously enhance the leak tightness between the gun-top and the clay sleeve, completely solve the slurry run out producing in the gap between the gun-top and the clay sleeve and avoid the slow wind closure. Meanwhile, because the carbon asbestos fibre ring belt in front is provided with elasticity, the utility model can reduce the tremendous impact of the blast furnace clay gun on the tap hole area and prolong the service time of the blast furnace clay sleeve and the life of the blast furnace hearth.
Description
Technical field
The utility model relates to the technology of blocking up before the State of Blast Furnace, blocks up before particularly a kind of State of Blast Furnace with flexible big gun head.
Background technology
At present, the general big gun head that uses of blocking up before the State of Blast Furnace is linked together by big gun mouth body and the steel flush type big gun mouth form by socket.Use just effectively under the situation that not have to damage at mud cover, if when the mud cover damages (uneven or have pothole), there is the space in the mud cover with the big gun head, and stemming will be run out of from the gap when beating mud, need slow wind in the time of seriously just can finish and block up, and influences the ordinary production of blast furnace.
Blast furnace gun composite gun head: on the big gun head, be connected with non-rigid big gun head mouth, this big gun head mouth can be wooden, paper fiber, asbestos and wood composite material, can realize the sealing of blast furnace gun big gun head and mud inner room, reduce and prevent to beat the race mud phenomenon of mud process, realize maintenance blast furnace taphole.It is characterized in that: be connected with non-rigid big gun head mouth on described big gun head, this big gun head mouth can be wooden, paper fiber, asbestos and wood composite material.
This structure big gun head can only guarantee not run mud under mud cover and the unspoiled situation of big gun head mouth, the big gun head mouth of blast furnace gun composite gun head lacks enough intensity and resistance to elevated temperatures, adding its front end is the plane, so can only slight mud cover be damaged effectively, can not thoroughly solve the mud problem of running.
Summary of the invention
The purpose of this utility model is blocked up with flexible big gun head before being to design a kind of State of Blast Furnace, improves the stopping property of big gun head and mud inner room, stops to run mud, avoids slow wind locking mouth.
For achieving the above object, the technical solution of the utility model is,
Block up before a kind of State of Blast Furnace with flexible big gun head, be connected on the hydraulic pressure big gun body; Comprise, the big gun mouth, it is a tube structure, an end is connected on the hydraulic pressure big gun body; Steel ring is connected on the big gun mouth, and the one side has groove along circumference; Pad, the one side surface forms a bulge-structure, is embedded in the groove of described steel ring; Pressure ring is pressed on the pad in the steel ring groove.
Further, described big gun mouth end face has groove, and the end face of the relative big gun mouth of described steel ring is provided with fixedly projection, this fixedly the groove opened of projection shape and described big gun mouth end face be complementary, and be embedded and be fixed in this groove.
The fixedly projection of the groove of described big gun mouth end face and the end face of steel ring is the dovetail structure.
Again, described pressure ring is a carbon element fibrous magnesium silicate ring.
Be connected on the hydraulic pressure big gun body by the big gun mouth, the trough of belt steel ring is connected on the big gun mouth by the form of socket, pad is set in the groove of trough of belt steel ring, high spot is aimed at the orientation that the mud cover damages, at last, the pressure ring of carbon element fibrous magnesium silicate is pressed in the trough of belt steel ring, thereby makes the front end of this big gun head have a place to be projection.
In the process of tapping a blast furnace, damage if find the mud cover, former steel flush type big gun mouth is unloaded, overlap the convex pad that the degree of damaging is selected suitable thickness for use according to mud, this convex big gun head mouth is connected on the big gun mouth blocks up, then can finish the process of blocking up, stop to run mud, avoid slow wind locking mouth.
Iron mouth place temperature is selected carbon element fibrous magnesium silicate pressure ring for use more than degree more than 1,000, it has great high-temperature resistant, also have flexibility simultaneously,, can be bumped into breach when mud overlaps when jagged, other place, plane then is crushed, and makes big gun head and mud be locked to connect airtight and touches, and is unlikely race mud.This material also has certain intensity, can be by the avulsion of clay gun pressure after clay gun compresses.
When blocking up, clay gun compresses carbon element fibrous magnesium silicate pressure ring, and its stressed back produces distortion, fills up mud cover recess, and big gun head and mud are locked to connect airtight and touch, and can not produce the space, guarantee to block up successfully.After the use, carbon element fibrous magnesium silicate pressure ring is taken off, load onto new pressure ring, can continue to use.
The beneficial effects of the utility model
The utility model cooperates by using convex pad, trough of belt steel ring, convex pad and carbon element fibrous magnesium silicate ring are fixed in the trough of belt steel ring with inset type, can significantly improve the stopping property of big gun head and mud inner room, solve the race mud phenomenon of the space generation of big gun head and mud inner room up hill and dale, avoid slow wind locking mouth; Simultaneously, because the carbon element fibrous magnesium silicate endless belt tool flexibility of front end can reduce the enormous impact of blast furnace gun to the iron oral region, prolong blast furnace mud cover duration of service and blast furnace hearth life-span.

Fig. 2 is the structural representation of the utility model one embodiment.
Embodiment
Referring to Fig. 1, Fig. 2, block up before the State of Blast Furnace of the present utility model with flexible big gun head, be connected on the hydraulic pressure big gun body; Comprise, big gun mouth 1, it is a tube structure, and an end is connected on the hydraulic pressure big gun body, and big gun mouth end face has groove 11; Steel ring 2 is connected on the big gun mouth 1, and one side 21 has groove 211 along circumference, the end face 22 of its relative big gun mouth 1 is provided with fixedly projection 221, should be fixedly the groove 11 opened of projection 221 shapes and described big gun mouth 1 end face be complementary, be the dovetail structure, and be embedded and be fixed in this groove 11; Pad 3, one side surface form a bulge-structure 31, are embedded in the groove 211 of described steel ring 2; Pressure ring 4 is pressed on the pad 3 in steel ring 2 grooves 211, and it is a carbon element fibrous magnesium silicate ring.
