Description
Technical field
The utility model relates to field of steel metallurgy, belong to steel mill fan-shaped sections of slab continuous spray tube spray gun structure
It improves, especially a kind of spray spray gun for replacing continuous casting segment online using special assembling tool.
Background technique
In continuous-casting of steel billet production process, high-temperature molten steel is cooling by crystallizer, and the green shell of slab is initially formed, using
The aerosol that every section of fan-shaped section spray system generates persistently cools down, and steel billet solidifies from outside to inside, then is aligned, and qualified steel is eventually become
Base.
The spray system of conticaster is the most crucial device of conticaster, and spray system directly influences the quality of slab.Even
Casting machine spray system mainly includes fan-shaped section secondary cooling compressed air hose, fan-shaped section secondary cooling water pipe and is attached thereto
Aerosol spray gun etc..
The quality of sheet billet continuous casting fan-shaped section secondary cooling spraying effect directly influences slab quality, if the nozzle of spray gun
Blocking, will cause surface quality of continuous casting plate bland defect, such as corner crack, star-like crack etc.；Slab internal soundness defect includes three
Angular region crackle, central crack etc..It is also easy to generate the blank shapes defects such as bulge, seriously affects the quality of continuous casting steel billet.
Although having in slab production process to secondary cooling water water quality and strict requirements.But it is sprayed in secondary cooling and is
It unites under the hot conditions environment that uses, since scale, greasy dirt and microorganism etc. cause spray nozzle clogging to lose the thing of refrigerating function
Therefore it happens occasionally.And randomness is presented in the blocking of nozzle, (the blocking quantity of nozzle, which arrives greatly, seriously affects slab quality when serious
When) just needing to interrupt production, maintenance down hangs production line to the fan-shaped section there are spray nozzle clogging and carries out dismounting and change nozzle etc.
Upkeep operation.Again up the fan-shaped section replacement fixed before.It is every to carry out primary such fan-shaped section replacement operation, this
Process needs 3 to 5 hours time, seriously affects the production efficiency of conticaster.
Intrinsic nozzle and the spray gun body of rod are linked together, due to the limitation of the fan-shaped section working space of conticaster, in life
Plug nozzle is replaced in producing line to be difficult to realize, and spray gun and nozzle can only be replaced when fan-shaped section carries out off-line maintenance operation.
Utility model content
The purpose of this utility model is to provide a kind of sprays for replacing continuous casting segment online using special assembling tool
Spray gun, structure is reasonable and the performance is reliable, can replace spray gun online, saves the repair time, improves production efficiency.
Purpose of the utility model is realized as follows: a kind of replace continuous casting segment using special assembling tool online
Spray gun is sprayed, spray spray gun is that its structure of segment type spray gun is to be made of mutually matched spray gun upper body of rod with spray gun lower body of rod,
Upper end has the spray gun upper body of rod of air water incoming end, and taper sleeve type spray gun bellmouth is arranged in lower end, and upper end has the spray gun of socket
Nozzle is arranged in its lower end of lower body of rod, is matched between the bellmouth of spray gun upper body of rod and the socket of spray gun upper body of rod by sealing ring sealing
It closes；The structure of special assembling tool is to be arranged hydraulic cylinder in magnetic holding device sleeve, and sleeve upper end hinged two is symmetrical
The articulated opposite opened semi-ring fixture in outside connecting rod the upper end, two hinged symmetrical inner link the upper ends of hydraulic cylinder piston rod upper end
It is hinged on clip arm, opposite opened semi-ring fixture and spray gun lower beam mates.
Working principle of the utility model is:
The fan-shaped section spray system of the utility model design, the spray gun body of rod change into merogenesis by original integral design
Formula, i.e. a spray gun body of rod are divided into two sections.One end of upper body of rod is connected with compressed air hose and water pipe line, and the other end is designed to
Bellmouth, inner wall circumferentially design twice annular groove；One end of lower body of rod connects nozzle, and the other end is designed to socket, outer wall edge
Circle designs twice annular groove (seal groove), built-in high-temperature resistant seal ring.Two pole bodies are attached by bell and spigot, socket joint
It is sealed between mouthful using two pass high-temperature resistant seal ring.
It dismantles the band nozzle body of rod blocked: making opposite opened semi-ring fixture first and with lower body of rod in vertical direction pair,
Handle rotates 90 degree to horizontal position, and hydraulic cylinder starting, the elevating lever being connected with hydraulic cylinder rises, when the band nozzle body of rod passes through open type
The semi-ring fixture center of circle, puts the power knob on fixed handle, and open type semi-ring fixture holds the spray gun body of rod, hydraulic cylinder piston rod descent tape tightly
Dynamic to be attached thereto the elevating lever decline being integrated, the spray gun body of rod with nozzle is extracted out of another section of spray gun body of rod bellmouth, is examined
Repair the body of rod that work removes spray nozzle clogging.
Intact nozzle body of rod process: crawl power knob is assembled, the intact band nozzle body of rod, folder are clamped on tool
Next handle rotates 90 degree and starts hydraulic, to be connected with hydraulic cylinder elevating lever rising to horizontal position cylinder, when inserting with the nozzle body of rod
Mouth is inserted into bellmouth with after the bellmouth centering of another section of body of rod, and two sections of bodies of rod of spray gun are connected as one, and electromagnet fixture is magnetic
It disappears, encircles clamping and loosen, fixture is detached from with the nozzle body of rod.Hydraulic cylinder piston rod decline, which drives, is attached thereto the liter being integrated
Bar decline is dropped, and replacement plug nozzle work terminates.
The good effect that the utility model generates:
The utility model is the spray gun Optimal improvements to secondary cooling water spray system, and newly-designed spray gun can online more
It changes, does not need continuous casting machine fan-shaped segment to dismantle, hangs continuous casting machine production line.Gap is shut down using production process, is counted according to production
Spray gun replacement operation is carried out after drawing the pouring time of replacement steel grade or tundish, the repair time is saved, improves production effect
Rate.
The utility model is structurally reasonable, reliable performance, realizes online replacement spray gun, saves the repair time, improve
Production efficiency.
