Description
Technical field
The present invention relates to hot-rolling mill strip production fields, and in particular to a kind of Rapid Cleaning continuous casting two cold filter, spray boom,
The system and method for nozzle.
Background technology
Two cold filter of steel mill, spray boom, spray nozzle clogging are a hard nut to cracks, due to conticaster drier oil, hydraulic oil
During leakage, substantial amounts of hydraulic oil enters the secondary cooling water circulatory system, generates a large amount of greasy filth and causes secondary cooling water filter, spray boom, nozzle
It blocks, and current two cold filter is larger to sludge filtration difficulty.Since the blocking of di-cold spray nozzle causes strand cold in fan-shaped section
Uneven, cooling is not enough.Inhomogeneous cooling causes the surface defects such as the various face cracks of strand, off-square.Cooling can not enough cause to cast
Base bulge or even bleed-out.
The mode cleared up at present mainly manually cleans filter, spray boom, nozzle, frequent due to blocking, and workload
Quite big, effect is poor, often clear complete di-cold spray nozzle, one pour time after block again.
The content of the invention
To overcome the deficiency, the present invention provide a kind of Rapid Cleaning continuous casting two cold filter, spray boom, nozzle system and
Method the characteristics of mainly for greasy filth tamper, dissolves greasy filth using high temperature and high pressure steam, achievees the purpose that Rapid Cleaning.
The technical solution adopted in the present invention is：A kind of Rapid Cleaning continuous casting two cold filter, spray boom, the system of nozzle,
Including two cold filters, spray boom, nozzle, high temperature and high pressure steam pipe, the import of the two cold filter is cold with two by water inlet pipe
Total valve of intaking connects, the outlet corresponding spray boom and nozzle of two cold filters, and the water inlet pipe is equipped with bypass high temperature and pressure and steams
Steam pipe road, high temperature and high pressure steam pipeline are connected with steam generation facility, and high temperature and high pressure steam pipeline is equipped with steam valve.
Specifically, the steam generation facility is using the flue Steam Recovery boiler in steel mill.
A kind of Rapid Cleaning continuous casting two cold filter, spray boom, the method for nozzle, including following technique：
(1) high temperature and high pressure steam pipeline is increased between caster two cold total valve and two cold filters, it is desirable that steam is
Saturated vapor, pressure >=1.5MPa, temperature >=150 DEG C；
(2) cleaning process：S1, two cold water inlet total valves are closed after the completion of conticaster one pours time；S2 opens fan-shaped
Steam valve between section secondary cooling water water inlet total valve and two cold filters on high temperature and high pressure steam pipeline, progressively opens to the maximum,
Two cold filters, spray boom, nozzle are cleaned.
Specifically, in order to improve cleaning performance, in cleaning process, spray boom is divided into different groups, a point different branch is distinguished
It is cleaned, ensures that branch pressure is maximum.
Specifically, it is ineffective for the nozzle or spray boom that have blocked, nozzle, spray boom can be unloaded in advance, then into
Row cleaning, improvement effect.
Specifically, improve steam clean the frequency can also improvement effect, keep nozzle be chronically at kilter.
The invention has the advantages that：The characteristics of for greasy filth tamper, dissolves greasy filth using high temperature and high pressure steam,
Achieve the purpose that Rapid Cleaning；Labor intensity is very small, and the filter, spray boom, nozzle after cleaning can keep dry the long period
Only, blocking interval time is long again, is conticaster production run, ensures that slab quality provides guarantee；The cigarette of BOF steelmaking shop
Road Steam Recovery boiler can meet the condition requirement of this method steam, therefore can utilize itself completely for BOF steelmaking shop
Resource realizes cleaning process, saves and utilizes resource.
Description of the drawings
Fig. 1 is the structural diagram of the present invention.
1 two cold water inlet total valves, 2 two cold filters, 3 water inlet pipes, 4 outlet pipes, 5 spray booms, 6 nozzles, 7 high temperature and high pressure steams
Pipeline, 8 steam valves.
Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.
A kind of Rapid Cleaning continuous casting two cold filter as shown in Figure 1, spray boom, the system of nozzle, including two cold filters
2nd, spray boom 5, nozzle 6, high temperature and high pressure steam pipeline 7, the import of the two cold filter 2 are total by the cold water inlet of water inlet pipe 3 and two
Valve 1 connects, and the outlet of two cold filters 2 is connected with outlet pipe 4, and multiple spray booms 5, the end of spray boom 5 are connected on outlet pipe 4
Nozzle 6 is set to, the water inlet pipe 3 is equipped with bypass high temperature and high pressure steam pipeline 7, high temperature and high pressure steam pipeline 7 and steam generation
Device is connected, and high temperature and high pressure steam pipeline 7 is equipped with steam valve 8.
Specifically, the steam generation facility is using the flue Steam Recovery boiler in steel mill.
A kind of Rapid Cleaning continuous casting two cold filter, spray boom, the method for nozzle, including following technique：
(1) high temperature and high pressure steam pipeline 7 is increased between caster two cold intakes 1 and two cold filter 2 of total valve, it is desirable that
The steam of conveying be saturated vapor, pressure >=1.5MPa, temperature >=150 DEG C；
(2) cleaning process：S1, two cold water inlet total valves 1 are closed after the completion of conticaster one pours time；S2, fan is opened
