Abstract
The utility model discloses a kind of emergent stifled iron notch tools of blast furnace, including reinforcing bar, grasp, drill bit, fastening bolt and stifled body, the stifled body is in taper type, it is equipped with the reinforcing bar with grasp at the middle part of stifled body, the bar connecting drill bit and stifled body are diametrically equipped with fastening bolt in drill tip；The stifled body is solidified by refractory clay.The utility model can effectively solve long-time blowing-out process accident caused by not blocking up iron mouth because of clay gun before and lose.
Description
Technical field
The utility model is related to blast furnace stifled iron notch tools, and especially carrying out tapping machine in the state that clay gun blocks up failure answers
The emergent stifled iron notch tool of the blast furnace of anxious stifled iron notch or artificial stifled iron notch.
Background technology
The stifled iron notch equipment used before State of Blast Furnace at present is clay gun, and stemming is thrown into iron mouth using clay gun, so that it may with by iron
Mouth blocks, and continues to smelt inside blast furnace.But clay gun is it is possible that failure loses function of blocking up, once not blocking up iron mouth will
Blast fumance is interrupted, the accidents such as slag iron landing, personal injury can be also caused, is one of stokehold considerable safety production hidden danger.
Utility model content
In order to block iron mouth when ensureing clay gun failure, the utility model provide a kind of tapping machine meet an urgent need stifled iron notch or
The security tool manually blocked up can effectively solve long-time blowing-out process accident caused by not blocking up iron mouth because of clay gun before and damage
It loses.
The technical solution adopted in the utility model is：A kind of blast furnace is met an urgent need stifled iron notch tool, including reinforcing bar, grasp, drill bit,
Fastening bolt and stifled body, the stifled body are in taper type, are equipped with the reinforcing bar with grasp at the middle part of stifled body, the reinforcing bar connects
Drill bit and stifled body are connect, fastening bolt is diametrically equipped in drill tip；The stifled body is solidified by refractory clay.
The utility model has the beneficial effects that：When clay gun, which loses, blocks up function, which is installed to tapping machine front end,
The tools for alignment iron mouth is sent into using feeding motor, is held out against by rotation tapping machine, can restore raw in stove within a short period of time
Production.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structure chart of horn mouth ferrule mold.
Specific implementation mode
The utility model will be further described below with reference to the accompanying drawings.
It meets an urgent need stifled iron notch tool as shown in Figure 1, the utility model is a kind of blast furnace, including reinforcing bar 1, grasp 2, drill bit 3, tight
Fixing bolt 4 and stifled body 5.Smooth processing is carried out to 50 bit faces of φ on tapping machine, the reinforcing bar 1 of 150mm long, which is welded on, removes conjunction
On the drill bit 3 of golden cutter head.It is welded with grasp 2 on reinforcing bar 1, the threaded hole of M12 is machined in the side of 3 screw buckle of drill bit, it will
Reinforcing bar 1 is put into the horn mouth casing that a detachable overall length is 200mm, refractory clay is filled inside pipe sleeve, resistance to
The stifled body 5 of taper type is formed after the solidification of chamotte material.
End blocking tool can be connect with opening driver drilling rod by the screw buckle of drill bit, it will using the feeding function of tapping machine
End blocking tool fills in Tie Kou, and after it is firm, reversion drilling rod makes drilling rod be detached from end blocking tool.
The utility model is simple and reliable, easily manufactures, uses and replaces, and cost is relatively low；Once problem occurs for clay gun not
It can block up, installing end blocking tool using tapping machine can be completed work of blocking up, and ensure blast fumance；Stokehold is substantially increased to set
Standby stability and validity, blast fumance are protected.
