Description
Technical field
The present invention relates to a kind of cutting slag cleaning plant, a kind of energy-efficient cutting slag cleaning rifle.
Background technology
Currently, the slag tumor (being commonly called as dross, also referred to as burr) that steel mill's continuous casting line strand flame cutting is formed, always
The problem that steel making working procedure is relatively scratched one's head, is because: these casting blank section bottoms and the slag tumor of corner, both sides, directly affects next
Operation-steel rolling.If these slag tumors are not cleared up before strand enters steel rolling process, on the one hand can directly cause strand feed mill
Difficulty, has a strong impact on rolling mill practice and rolling efficiency.On the other hand the slag tumor of casting blank section is transported at a high speed when entering milling train
The roll turned pulverizes, and a large portion is ground in stocking, forms a lot of rough oxidation cinder hole on stocking surface.Cause
For through after roll continue rolling, until finished product, stocking is that thickness is the most thinning, area progressively becomes big, so being equal to is by residual
Substandard products area is progressively exaggerated.The large area that slight slag tumor causes milling material is defective, has had a strong impact on rolling quality
Amount and rolling lumber recovery.
To this end, all steel mills all can not stint input, adopt all necessary measures and method to allow people be vexed this
" burr " is removed.
Currently mainly take two ways to remove the slag tumor (being commonly called as dross, also referred to as burr) of casting blank section corner
It is: artificial chisel, flat chisel or by directly beaing removal with hammer.This be the most original be also maximally effective a kind of unhairing
Thorn method (can accomplish to let slip not at all).But, labor cleaning gets up that labor intensity is big, tool wear fast (slag tumor and
Strand degree of fusion is good, fusion intensity high), (all between several tons to tens tons, deburring to wait until every block casting base length service cycle
After the temperature of strand lowers, the strand of stacking is scattered by overhead traveling crane to be utilized, and just can carry out labor cleaning's burr work,
Stack is also wanted after having cleared up), human and material resources, financial resources, equipment investment are big, and danger coefficient is high, and work efficiency is extremely low.Two are: profit
Remove with special equipment flash trimmer.Due to this body structure of flash trimmer and own characteristic thereof, the application of flash trimmer is caused to be subject to
To following circumscribed restriction.(1) the equipment initial stage puts into big, energy consumption height: at present, flash trimmer substantially price is in RMB 700,000
About unit, cost of equipment is high, the initial stage puts into big；Additionally flash trimmer complete machine match power is at about 70 kilowatts, and power consumption is high, so
Big power consumption can deserve to be called a no small spending for the slim profit that continuous-cast blank produces.(2) floor space
Greatly, production line length is long: starting so that continuous casting line overall length increases substantially of flash trimmer equipment, the thing followed is Factory Building
Span wants big, and Factory Building and auxiliary facility initial stage put into big.(3) flash trimmer floor space is big, determines that flash trimmer can only be applied
In single current or the two parallel sheet slabs of stream, and the parallel small billet of the compact multithread that occupies the bigger market share, rectangular bloom, little
The continuous casting lines such as slab cannot use at all.(4) flash trimmer self structure and process characteristic determine that another is occupied relatively by it
The round steel billet burr that the round billet continuous casting machine of the big market share is produced is willing and yet unable to help (because circle base dross is the most flat at one
The arc surface in face) (5) flash trimmer tool wear is fast, maintenance workload is big, operating cost is high: flash trimmer is to pass through high-speed rotary
The fly cutter rotary-cut turned or a lot of circular arc cutting knife rely on forward and reverse movement of semifinished product " to scrape " to fall, due to burr i.e. slag tumor and casting
Base degree of fusion is good, fusion intensity is high, causes tool wear block, and maintenance workload is big, and operating cost is high.On the other hand, continuous casting is
Casting continuously, in a casting cycle, strand is continuously toward going out, even if finding tool wear, deburring effect
Dying, be also not do enough time to shut down and change, can only by with！By the time after this cast terminates, then shut down more
Change, so personnel at the scene have same common recognition: when just having changed cutter, the deburring effect of flash trimmer is exactly good, but good
Jing Buchang, there is abrasion in cutter one, and deburring effect is had a greatly reduced quality immediately.
In view of As-Is, we, in line with the Innovation principle of " high-quality, efficient, energy-saving and environmental protection ", have developed: efficiently save
Can cutting slag cleaning rifle.
Summary of the invention

Pipe 5, stainless steel bend 12, stainless steel tube (with 5) screw-threaded coupling joint (with 3), locking nut 11 and peripheral hardware water supply connector 6, go out
Water swivel 10 grade forms.Described nitrogen (or compressed air) pipe-line system by inlet suction port 1, air inlet connecting headstock 2, joint (with 7),
Flange-connection stainless steel metal flexible pipe 4, joint 7, air outlet adapter seat 8 etc. form.Described cooling water system is by gun body and nitrogen (or compression sky
Gas) pipeline combines, by related seals mechanism (teflin ring 13), the intermediate cavity formed and associated adapter forms.Institute
State blow slag nozzle 9 be by install additional between air outlet adapter seat red copper pad 14 (heat conduction and sealing) by screw-threaded coupling joint (with
3) and locking nut 11 screws connection.
Gun body water supply connector 6 and water out adapter 10 indicate " JS ", " CS " mark respectively, and the pipe joint that will indicate " JS " leads to
Cross a metal hose to be connected with continuous casting cutting gun water out adapter, the pipe joint indicating " CS " is cut with former by another metal hose
Rifle water return pipeline connects (or being fixed by the other end in line), completes cooling water system and connects.Inlet suction port 1 indicates " JQ " mark,
The inlet suction port that " JQ " indicates will be indicated, controlled with from energy-efficient cutting slag cleaning rifle source of the gas by a metal hose
Nitrogen (or compressed air) pipeline of case is connected, and completes gas circuit and connects.
When flame cutting machine burning torch cutting oxygen is opened, when starting to cut steel billet, the cleaning rifle PLC control of energy-efficient cutting slag
System processed receives signal, and in source of the gas control chamber, nitrogen (or compressed air) electromagnetic valve obtains electric opening, and gases at high pressure are by efficiently
Flange-connection stainless steel metal flexible pipe 4 in energy-conservation cutting slag cleaning rifle gun body, is blown slag nozzle 9 ejection at a high speed by special so that high velocity air
Flame cutting cuts the oxidizing slag that oxygen blows down blow away.Meanwhile, play the effect quickly cooling down casting blank section corner, make cutting oxygen
The oxidizing slag that stream is quickly blown down cannot fuse with strand corner, thus fundamentally stops the formation of slag tumor, thoroughly solves
Casting blank section corner dross problem.
After cutting, flame cutting cutting oxygen is closed, and energy-efficient cutting slag cleaning rifle PLC control system receives
Signal, in source of the gas control chamber, nitrogen (or compressed air) electromagnetic valve dead electricity is closed, and waiting is ordered next time.
The above is the preferred embodiment of the present invention, it is noted that come for those skilled in the art
Saying, on the premise of without departing from the technology of the present invention principle, it is also possible to make some improvement and deformation, these improve and deformation also regards
For protection scope of the present invention.
