Abstract
The utility model discloses Quick-action opening blocking-up device before a kind of State of Blast Furnace, comprise pedestal, big gun lip, it is characterized in that: welded sleeve on the inwall of described big gun lip, the external diameter of sleeve is identical with the internal diameter of big gun lip, for 150mm, sleeve wall thickness is 2mm, and its external port is concordant with big gun lip front end; Described big gun lip is annular plate, and the side of annular plate and sleeve connection is notch cuttype, and the side be connected with pedestal is wedge shape.After which solves blast furnace big gun mouth melting loss, at high temperature the long period changes a difficult problem for big gun mouth, reduces labour intensity, decreases blast furnace taphole and see the injury of blowing to workman in rear replacing big gun mouth operation process.
Description
Technical field
The utility model relates to Quick-action opening blocking-up device before a kind of State of Blast Furnace, belongs to mechanical field.
Background technology
Usually, blocking up of blast furnace, after seeing at iron mouth and blowing (the significant phenomenon that a kind of blast furnace is blocked up), utilizes Hydraulic clay gun to squeeze in blast furnace taphole by the mud in Hydraulic clay gun, when high temperature and high pressure, the rapid intensity of stemming uprises, and the slag iron in blast furnace is no longer flowed out.But, under special circumstances, close the door when such as iron mouth does not blow, or have foreign matter to support below iron mouth at closing time, the big gun mouth of Hydraulic clay gun cannot be combined closely with iron mouth, and now, the slag iron of high temperature just can be gone out from the gap between big gun mouth and iron mouth, iron mouth big gun mouth just can be melted, and finally causes blast furnace normally to block up.In this case, necessary integral replacing big gun mouth, but because the pin of fixing big gun mouth is due to the effect of high-temperature expansion and the cohesive action of slag iron between pin and big gun mouth body, be very difficult to unload and carry out the operation of replacing big gun mouth, now, blast furnace is often forced to significantly checking (checking is a kind of behavior of havoc smooth operation of furnace), and blast-furnace man is forced at high temperature change big gun mouth for a long time, labour intensity and hazard level very big.
Summary of the invention
The utility model provides Quick-action opening blocking-up device before a kind of State of Blast Furnace, in the blowout of iron mouth, when big gun mouth is by molten iron is melting, do not unloading big gun mouth, blast furnace also need not carry out blocking up operation when checking, thus reduces the impact on blast furnace, the impact on personal security.
The technical solution adopted in the utility model is: Quick-action opening blocking-up device before a kind of State of Blast Furnace, comprises pedestal, big gun lip, it is characterized in that: welded sleeve on the inwall of described big gun lip, the external diameter of sleeve is identical with the internal diameter of big gun lip, for 150mm, sleeve wall thickness is 2mm, and its external port is concordant with big gun lip front end; Described big gun lip is annular plate, and the side of annular plate and sleeve connection is notch cuttype, and the side be connected with pedestal is wedge shape.
Described sleeve overall length is 150mm, and material is straight carbon steel.
The utility model is in the blowout of iron mouth, and big gun mouth is used by when molten iron is melting, and does not need to unload big gun mouth, directly carries out blocking up operation, and the slag in the big gun mouth of melting loss, iron, mud unwater only by concrete implementation method: A.;
B. being loaded by this emergency unit in pedestal (makes it enter with sledgehammer impact interior), guarantees that impaired big gun mouth body is by the sleeve stopper in this emergency unit;
C. this emergency unit and pedestal electric welding are carried out 3 electric welding (in 120 ° of angles between 3);
D. normally to close the door operation.
The utility model provides a kind of device of blocking up fast newly, when big gun mouth pedestal need not be changed, only this Quick-action opening blocking-up device directly need be filled on the big gun mouth be melted, and the position utilizing this device big gun mouth to be subject to the fusing of slag iron stops, thus realize changing big gun mouth, reach the object of blocking up rapidly, and then reduce the various harm about production and safety aspect.
The beneficial effects of the utility model: the difficult problem at high temperature changing big gun mouth after 1. solving blast furnace big gun mouth melting loss for a long time, reduces labour intensity, decrease blast furnace taphole and see the safety hazard blowing workman in rear replacing big gun mouth operation process;
2. avoiding blast furnace cannot block up because big gun mouth is impaired, in order to change the significantly checking operation that big gun mouth carries out, stabilizing conditions of blast furnace;
3. the plain carbon stool sleeve of the utility model employing, overall length is 150mm, and the effect of sleeve is to stop the position of big gun mouth fusing; Length sleeve is arranged to 150mm, and the depth of fusion maximum with big gun mouth is identical.
Below in conjunction with drawings and Examples, the utility model is described further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
In figure, 1 is sleeve, and 2 is big gun lip.
Embodiment
Embodiment:
As shown in Figure 1, 2, Quick-action opening blocking-up device before a kind of State of Blast Furnace, comprises pedestal, big gun lip, it is characterized in that: welded sleeve 1 on the inwall of described big gun lip 2, the external diameter of sleeve 1 is identical with the internal diameter of big gun lip 2, is 150mm, sleeve 1 wall thickness is 2mm, and its external port is concordant with big gun lip 2 front end; Described big gun lip 2 is annular plate, and the side that annular plate is connected with sleeve 1 is notch cuttype, and the side be connected with pedestal is wedge shape.
Described sleeve overall length is 150mm, and material is straight carbon steel.
Concrete making method is:
1. immediately the slag of the big gun mouth inside of melting loss, iron, mud are cleaned out, load smoothly to enable this emergency unit.
2. this emergency unit sledgehammer is squeezed into big gun mouth pedestal.
3. 3 electric welding (in 120 ° of angles between 3) are carried out in the big gun lip electric welding of this emergency unit and former big gun mouth, make it fix.
4. Hydraulic clay gun is to mud, makes big gun lip be full of stemming.
5. door-closing operation is implemented.
