Abstract
The utility model discloses a stifled iron mouthful device of blast furnace hydraulic pressure mud bubble accident situation belongs to metallurgical equipment technical field. The utility model aims to provide a can replace the operation of blocking up of big gun head when accident situation is met to the in -process of blocking up at blast furnace hydraulic pressure clay gun, avoid the stifled iron mouthful device of blast furnace hydraulic pressure mud bubble accident situation of underproduction loss, including the big gun head, the device still includes the insertion section who is connected with the big gun head, big gun head and insertion section cross -section are ring shape, the inside stemming fill area that is equipped with of big gun head and insertion section. This device uses when being applicable to various blast furnace hydraulic pressure mud bubble accident situation.
Description
Technical field
This utility model is specifically related to a kind of blast furnace hydraulic mud bubble accident condition stifled iron notch device, belongs to technical field of metallurgical equipment.
Background technology
Blast furnace hydraulic mud steeps, and belongs to the casthouse equipment that smelting industry is indispensable, and its effect is can the most accurately to block the tapping hole after putting ferrum, makes blast furnace rapidly enter the operation of subsequent cycle.If blast-furnace hydraulic mud gun is event when anything crops up during blocking up, cause big gun head thorn bad, it is impossible to block ferrum mouth smoothly；Or directly Hubei Province portion contacted with big gun head being stung bad, it is necessary to damping down changes big gun head and Hubei Province portion, if carried out checking or damping down operation, necessarily causes the underproduction to lose.
Utility model content
Therefore, the purpose of this utility model is to provide one and big gun head can be replaced when blast-furnace hydraulic mud gun meets accident condition during blocking up to carry out blocking up operation, avoid the blast furnace hydraulic mud bubble accident condition stifled iron notch device that the underproduction is lost, including big gun head, described device also includes the inserting paragraph being connected with big gun head, described big gun head and inserting paragraph cross section are annular, are provided with stemming fill area inside described big gun head and inserting paragraph.
Further, described blast furnace hydraulic mud bubble accident condition stifled iron notch device entirety is made up of HT200 type casting pig.
Further, described big gun head cross-sectional outer diameter a size of 250mm, big gun head cross section internal diameter size is 150mm, big gun head thickness is 50mm～100mm, described inserting paragraph cross-sectional outer diameter a size of 148mm, inserting paragraph cross section internal diameter size is 130mm, inserting paragraph a length of 140mm, 150mm or 200mm.
The beneficial effects of the utility model are: a kind of blast furnace hydraulic mud bubble accident condition stifled iron notch device of the present utility model, can manufacture and design according to the internal diameter size in Hydraulic clay gun Hubei Province portion and big gun head, when chance ferrum mouth does not blocks up accident conditions such as causing the breakage of big gun head, by solid for this device stemming, it is inserted directly in the Hydraulic clay gun big gun head of breakage, both can carry out stifled iron notch operation, decrease workman's activity duration in high temperature environments, the most safe, reliable and convenient fast.Reduce again that blast furnace causes because ferrum mouth does not blocks up stop checking number of times, it is to avoid underproduction loss.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model a kind of blast furnace hydraulic mud bubble accident condition stifled iron notch device；
Fig. 2 is the use view of this utility model a kind of blast furnace hydraulic mud bubble accident condition stifled iron notch device.
Reference is as follows:
1, big gun head；
2, inserting paragraph；
3, stemming fill area.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is illustrated:
As it is shown in figure 1, a kind of blast furnace hydraulic mud bubble accident condition stifled iron notch device, including big gun head 1, device also includes that the inserting paragraph 2 being connected with big gun head 1, big gun head 1 and inserting paragraph 2 cross section are annular, big gun head 1 and inserting paragraph 2 inside and are provided with stemming fill area 3.
Preferably, blast furnace hydraulic mud bubble accident condition stifled iron notch device entirety is made up of HT200 type casting pig.Big gun head 1 and inserting paragraph 2 entirety are made up of HT200 type casting pig, and fabrication and processing is convenient, and the cross section of its vertical axial is annular, and internal space forms stemming fill area 3, and HT200 type casting pig also has resistant to elevated temperatures feature.
Preferably, big gun head 1 cross-sectional outer diameter a size of 250mm, big gun head 1 cross section internal diameter size is 150mm, big gun head 1 thickness is 50mm～100mm, inserting paragraph 2 cross-sectional outer diameter a size of 148mm, inserting paragraph 2 cross section internal diameter size is 130mm, inserting paragraph 2 a length of 140mm, 150mm or 200mm.Overall dimensions can be adjusted, to adapt to different Hydraulic clay gun Hubei Province portions and the internal diameter size of big gun head.
The use state of this utility model a kind of blast furnace hydraulic mud bubble accident condition stifled iron notch device is as shown in Figure 2, chance ferrum mouth does not blocks up and causes big gun head breakage cannot block up ferrum, by solid for this device stemming, it is inserted directly in the Hydraulic clay gun big gun head of breakage, stifled iron notch operation can be carried out, bad clay gun Hubei Province portion is stung such as molten iron in stifled iron notch operation process, in the case, big gun head sledgehammer can be laid, accident stifled iron notch device is filled up mud, it is inserted directly in the portion of Hubei Province, stifled iron notch operation can be carried out.
During use, stemming fill area 3 is filled up with stemming, the stemming in blast-furnace hydraulic mud gun big gun head is plucked out certain space, the blast furnace hydraulic mud of populated mud is steeped accident condition stifled iron notch device and puts into the big gun head space scratched, stifled iron notch operation can be carried out.
This device is by certain steel plant 2500m3Blast furnace and 4500m3Apply on blast furnace, can change rapidly when accident condition, it is to avoid underproduction loss.
The above is preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
