Description
Technical field
The utility model belongs to Ferrous Metallurgy equipment technical field, and in particular to a kind of low consumed blast furnace casting opening
Machine.
Background technology
Steel market continuous slide in recent years, integrated iron and steel works' production and operation situation is increasingly serious, only makes great efforts to reduce
Enterprise's production cost, integrated iron and steel works could be supported to survive.
Before State of Blast Furnace during tapping outlet, during drill bit and drilling rod are advanced in taphole mud bag, closer to cupola well high-temperature region, institute
The hot-fluid of receiving is more, and because of drill bit and drilling rod is rotated in itself in high speed and the working condition of impact, is ceaselessly connect with stemming
Touch wiping, aggravate drill bit and the rubescent softening of drilling rod, when performance of then losing the job, particularly blow-on door to red of mud drum, lose
The drill bit and drilling rod of service behaviour are difficult to continue on a fire door and once open to wear, can only by increase drill bit or drilling rod consumption come
Improve fire door and open the rate of wearing, even result in iron mouth leakage iron when part, influence stokehold and tap a blast furnace work.
The method of drill bit drilling rod is protected during traditional tapping outlet free air cooling and nitrogen cooling, but in production practices
In, due to having O in air2In the presence of, the scaling loss of drill bit drilling rod is more accelerated when drill bit drilling rod is rubescent, and nitrogen cooling can also go out
The situation of existing drill bit scaling loss.Therefore how overcome the deficiencies in the prior art is current Ferrous Metallurgy equipment technical field urgent need to resolve
The problem of.
Utility model content
The purpose of this utility model is to solve the deficiencies in the prior art, there is provided a kind of low consumed blast furnace casting opening
Machine, it is excessive and bore that the blast furnace casting tapping machine solves drilling rod and drill bit scaling loss during generally blast furnace open hole
Lost the job the situation that performance causes iron mouth not open leakage iron after head drilling rod scaling loss, make opening process drill bit and drilling rod consumption big
The problem of width declines, while iron mouth is once opened the rate of wearing and greatly improve, improve blast fumance stability.
To achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of low consumed blast furnace casting tapping machine, including angling cylinder, rock drill, tapping machine cantilever, angling cylinder
Clutch end is connected with the power intake of tapping machine cantilever, and the clutch end of rock drill is connected with one end of bit shank；Pricker
The other end of tail is provided with delivery port, and the other end of bit shank is fixedly linked by one end of adapter sleeve and drilling rod；Drilling rod it is another
End is connected with drill bit, and drilling rod is hollow structure, and drill bit is provided with jet, and jet passes sequentially through drilling rod, adapter sleeve and bit shank
Delivery port be connected；Tapping machine cantilever is socketed in outside drilling rod；
Also include nitrogen tube and water pipe, nitrogen tube is connected with the two entrances of triple valve respectively with water pipe；Triple valve goes out
Mouth is connected by pipeline with the water inlet of bit shank.
It is further preferred that pipeline is metal hose.
It is further preferred that the entrance that nitrogen tube is connected with triple valve gradually subtracts along airflow direction, cross-sectional area
It is small.
Iron mouth channel environment, tapping machine structural behaviour and energy medium are combined by the utility model, bore opening process
Head and drilling rod consumption decline to a great extent；
Operation principle and process：The method of drill bit drilling rod is protected to be free air cooling and nitrogen cold during traditional tapping outlet
But, but in production practices, due to having O in air2In the presence of, the scaling loss of drill bit drilling rod is more accelerated when drill bit drilling rod is rubescent,
And the situation of drill bit scaling loss also occurs in nitrogen cooling.
Because water is significantly better than gas cooling to the cooling effect of drill bit drilling rod, the utility model passes through in tapping machine restocking
If industrial water lines, coupling with original nitrogen tube, nitrogen outlet is changed to " V " shape head, is easy to high pressure nitrogen that cooling water is broken up into mist
Change, filled by bit shank to drilling rod, reach the purpose that rod bit is protected in opening process.
Compared with prior art, its advantage is the utility model：
（1）About 2 ~ 3 drill bits are consumed before transformation per stove iron, 2 drilling rods, consume 1 drill bit, 1 brill after transformation per stove iron
Bar, part heat drill bit and drilling rod are repeatable to be utilized（I.e. single stove iron bit consumption ＜ 1；Drilling rod consumption ＜ 1）；
（2）Fire door once opens rate of wearing and improves about 10%, improves blast fumance stability.
