Abstract
This utility model is for problems of the prior art, the blast furnace providing drilling rod in a kind of Tie Kou of being easily opened, ferrum mouth opening procedure will not be stuck in ferrum mouth passage, can repeatedly utilize, reduce stokehold spare parts consumption is atomized tapping outlet drill rod, and it has U-type groove.
Description
Technical field
This utility model relates to technical field before metallurgy high furnace iron-smelting furnace, particularly relates to a kind of blast furnace atomization tapping outlet and exempts to bore
Head drilling rod.
Background technology
Present Domestic iron and steel production capacity surplus is serious, and enterprise to get a profit must drop unit cost by every possible means, improves enterprise
The industry competitiveness of product in market.Blast furnace ironmaking cost is mainly made up of two parts: original fuel consumption and stokehold standby redundancy in stove
Consume；Tapping outlet drilling rod belongs to stokehold standby redundancy consumption.
Existing blast furnace open hole drilling rod mostly is the drilling rod that cross section is circular strip drill bit, uses spiral shell between drilling rod and drill bit
Stricture of vagina connected mode.In actual production, there is two ways tapping outlet: 1, first open atomization with band drill bit round drill rod and be drilled into red point,
Disclosing tapping outlet with drill rod again, this method needs field worker repeatedly to change drilling rod and drill rod even uses the mode burning oxygen just can open ferrum
Mouthful, expend the time long, often because of in can not going out clean cupola well in time slag ferrum cause blast furnace checking, slow wind even hanging；2, directly use
Band drill bit round drill rod is opened atomization and is drilled ferrum mouth, and this method can quickly open tapping hole, but long at ferrum mouth passage stroke and to pass through
The red point of high temperature, drill bit consume is too much, and drill bit drainage exhaust duct is narrow and small during tapping outlet, holds when ferrum mouth is deep especially
Easily being blocked by stemming residue, atomization failure, stick of tool phenomenon occur, drill bit loses together with drilling rod；Existing blast furnace open hole
Drilling rod is not the most well positioned to meet the requirement that blast furnace ironmaking high efficiency low consumption produces.
Summary of the invention
This utility model is for problems of the prior art, it is provided that one is easily opened Tie Kou, ferrum mouth opening procedure
Middle drilling rod will not be stuck in ferrum mouth passage, can repeatedly utilize, reduce the blast furnace atomization tapping outlet of stokehold spare parts consumption and bore
Bar.
For preventing from beating tapping outlet overlong time, use blast furnace atomization tapping outlet drill rod, connect including adapter sleeve, cannulated threaded
Bar, hexagonal hollow drill pipe and U-type groove；Described hexagonal hollow drill pipe uses hexagonal steel to process, and its cross section is regular hexagon,
Adapter sleeve connecting portion all uses unified standard cannulated threaded to connect as the drilling rod that cross section is circular strip drill bit, it is simple to fast
Speed is changed.
For preventing drill bit and drilling rod during tapping machine tapping outlet to be stuck in ferrum mouth passage, using cross section is that circular strip is bored
It is deep that 0.5m in ferrum mouth passage is only crept in atomization left by the drilling rod of head, and following replacing hollow hexagonal drilling rod is opened atomization and continued to drill ferrum
Mouthful.Hexagonal hollow drill pipe uses hexagonal steel to manufacture hollow structure, and its cross section is regular hexagon, adds brill ferrum and makes a slip of the tongue
Drilling rod and the space of ferrum mouth passage in journey.
For improving drilling life of drill pipe, hexagonal drilling rod and whorl brace rod are hollow, and atomization can pass through, and hexagonal
Hollow drill pipe is not provided with drill bit, only processes a pair symmetrical wide 80mm, deep 30～the U-type groove of 50mm, tapping outlet at boring bar head
During the enough ambassadors of hole be atomized and can pass through, good cooling results, drill rod abrasion is less, and can be before next time tapping outlet
Continuing processing drilling rod front end 30～50mmU type groove, repeatable processing is used for multiple times.In production practices, the present utility model
Techniques below effect can be brought.
1, material used by the drilling rod of circular strip drill bit is 42CrMo alloy material, and price is: drill bit 50 yuan/；Drilling rod 300
Unit/root.Hollow hexagonal drilling rod material is 45# steel and does not use drill bit, and whole radical valence lattice are 150 yuan/root.Use from Liu Gang 6# blast furnace
From the point of view of situation, when not using hollow hexagonal drilling rod, circular strip drill bit drilling rod, bit consumption are respectively 24,100, averagely
Month drill bit drilling rod cost consumption adds up to be 10200 yuan；After using hollow hexagonal drilling rod, the drilling rod of monthly average circular strip drill bit is zero
Loss, a small amount of drill bit that only weares and teares is 52, and hexagonal drilling rod consumption is 28, the average moon drill bit drilling rod cost consumption add up be
6800 yuan；Year direct economic benefit is more than 40,000 yuan.
2, because changing hexagonal hollow drill pipe again with one 0.5m ferrum mouth passage of circular strip drill bit drilling rod subdrilling, so two
Plant drilling rod and connecting of adapter sleeve is threadeding of unified standard, Fast Installation and dismounting can be realized, improve tapping outlet speed
Degree, reduces the impact on blast fumance of the various burst accident, produces indirect economic effect.
3, this blast furnace atomization tapping outlet drill rod remains at drilling rod front end and processes 30～50mm Deep U Trenchs, keeps
The space of drainage exhaust, it is ensured that the effect of atomization cooling drilling rod front end, has stopped stokehold brill taphole drilling head and has been blocked up by stemming waste residue
Fill in drilling rod is stuck in ferrum mouth passage ferrum mouth of not opening and burn the phenomenon of oxygen, not only increase tapping outlet speed before State of Blast Furnace, Er Qiejie
Save alloy bit and circular cross-section drilling rod consumes.
