Abstract
A kind of fan-shaped section spray system is online and off-line cleaning plant and manufacture method, belongs to billet continuous casting machine secondary cooling water cooling technology field.This device includes saw blade, saw blade holding frame and holding rod；Saw blade is arranged on holding frame, and holding frame is connected by welding manner with holding rod；During cleaning, this device is repeatedly drawn send more than 10 times along parallel and spray direction.Advantage is, this apparatus structure is simple, cheap for manufacturing cost, small-sized one-handed performance of being easy to, saves and dismantles and install the time of spray total due to shower nozzle blocking, especially fan-shaped section outer arc, it is substantially reduced worker's activity duration, improves safety coefficient, it is ensured that spray water spray effect.
Description
Technical field
The invention belongs to billet continuous casting machine secondary cooling water cooling technology field, in particular, provide a kind of fan-shaped section spray system
Online with off-line cleaning plant and manufacture method, it is adaptable to spray in steel mill slab caster two cold water cooling system
Blocking cleaning, cleans efficient, simple and direct.
Background technology
Cooling water is mainly directly injected on casting billet surface by secondary cooling system, makes the rapid cooled and solidified of strand.
Use nozzle spray that cooling water can be made fully to be atomized in two cold-zones, and have higher jet velocity and penetrate a large amount of
The steam risen is ejected on casting billet surface equably, and area coverage wants big, but the cooling water of accumulation on strand
Lack.It is symmetrical that secondary cooling water jet quality directly affects slab quality and casting speed, the especially water distribution of secondary cooling water system
Floor blank conticaster.Fan-shaped section occurs spray clogging online at present, causes strand to have surface quality problems, tears open
Unload spray, cleaning spray and return dress spray and become and water one of steel work hard work task, how to ensure cleaning spray
How reducing labor intensity on the premise of drenching quality is the problem being currently needed for solving.
Summary of the invention
It is an object of the invention to provide that a kind of fan-shaped section spray system is online and off-line cleaning plant and manufacture method,
Solve that fan-shaped section is online and off-line due to spray nozzle blocking, repeated disassembled and assembled sprays and causes unnecessary labour force
Waste problem, decreases labor strength, on the premise of spray need not be dismantled, efficiently clears up spray nozzle
Device.According to fan-shaped section spray nozzle construction features and fan-shaped section roll system gap, in conjunction with two cold room structure, use spray
Drench blocking outward appearance phenomenon, utilize worker when two cold house's internal check spraying effects, it is possible to cleaning spray bifurcated is asked
Topic.
The cleaning plant of the present invention includes three parts such as saw blade, holding frame and holding rod, and saw blade is arranged on holding frame,
Holding frame is connected by welding manner with holding rod, and details is as depicted in figs. 1 and 2.During cleaning, by this dress
Put and repeatedly draw send more than 10 times along parallel and spray direction；Check spraying effect, if also clogging,
Again spray total dismounting is processed.Length of saw blade is 250mm
The making step of the cleaning plant of the present invention is as follows:
(1) measure spray nozzle sized data, measure minima between fan-shaped section upper roller system.
(2) make U-shaped saw bow, make a call to four holes above, dragsaw bar screw arbor assembly is installed.
(3) guide board structure is made.
(4) connecting rod is done in making, is welded to connect bar and saw bow.
(5) making hand-held rod member, this rod member can stretch.
(6) holding rod, holding frame and saw blade are assembled.
The use of apparatus of the present invention:
When checking fan-shaped section secondary cooling water spraying effect, carry this device.When finding spray blocking or bifurcated:
According to blocking spray to oneself distance, regulate holding rod length；Open with spray spray according to oneself position
Orientation angle, regulation holding frame direction and holding rod direction.This device is placed on blocking spray heads, slowly moves
Close to shower nozzle, holding frame two side shield first touches shower nozzle, then proceedes near shower nozzle, and saw blade just contacts spray.
During cleaning, this device is repeatedly drawn send more than 10 times along parallel and spray direction；Check spraying effect, if
Also have clogging, then spray total dismounting is processed.
Advantages of the present invention: this apparatus structure is simple, cheap for manufacturing cost, small-sized one-handed performance of being easy to, save by
Dismantle and install the time of spray total in shower nozzle blocking, especially fan-shaped section outer arc, it is substantially reduced worker
Activity duration, improve safety coefficient, it is ensured that spray water spray effect.

Detailed description of the invention
The cleaning plant of the present invention includes three parts such as saw blade, holding frame and holding rod, and saw blade is arranged on holding frame,
Holding frame is connected by welding manner with holding rod, and details is as depicted in figs. 1 and 2.
Device makes:
(1) spray nozzle sized data diameter 20mm is measured, sprinkler height 8mm, measure fan-shaped section upper roller system
Between minima 30mm.
(2) make U-shaped saw bow, make a call to four holes above, dragsaw bar screw arbor assembly is installed, in detail such as accompanying drawing Fig. 3
And Fig. 4.
(3) guide board structure such as accompanying drawing Fig. 5 and 6 is made.
(4) connecting rod is done in making, is welded to connect bar and saw bow.
(5) making hand-held rod member, this rod member can stretch.
(6) holding rod, holding frame and saw blade such as accompanying drawing Fig. 7 and Fig. 8 are assembled.
The use of device:
(1), when checking fan-shaped section secondary cooling water spraying effect, this device is carried.
(2) when finding spray blocking or bifurcated, first by this device detailed description of the invention:
A, according to blocking spray to oneself distance, regulate holding rod length；According to oneself position and spray
Orientation angle, simple adjustment holding frame direction and holding rod direction are opened in spray.
B., this device is placed on blocking spray heads, and slowly mobile close to shower nozzle, holding frame two side shield first connects
Contacting shower nozzle, then proceed near shower nozzle, saw blade just contacts spray.
C. this device is repeatedly drawn send more than 10 times along parallel and spray direction.
D. spraying effect is checked, if also clogging, then spray total dismounting is processed.
