Description
Technical field
The utility model belongs to steel-making continuous casting field, and in particular to a kind of crystallizer cooling water system.
Background technology
Crystallizer is the very important part of conticaster, is referred to as the heart of continuous casting installation for casting.In continuous casting production process
In, liquid metals solidifies the discharged heat overwhelming majority and is taken away by cooling water in a crystallizer, crystallizer cooling water system
During normal work, cooling water is that strand is cooled down indirectly by the cooling to copper plate of crystallizer so that casting stream from
Uniform green shell is formed when driving crystallizer, crystallizer cooling water uses closed loop sofe water, and cooling water passes through water pump forced feed knot
Brilliant device, after backwater enters heat exchanger cooling by overbottom pressure, then is used by pump pressurized circulation.
But when crystallizer cooling water system breaks down, when causing crystallizer cooling water pressure, flowed fluctuation, meeting
Influence slab quality, and if then influence production direct motion --- the cooling water flow into crystallizer is low, too small cooling current
Speed can cause cooling water before crystallizer is flowed out by be absorbed to the heat that substantial amounts of metal freezing discharged and steep temperature rise,
After temperature reaches the boiling point of water, vapor can be then produced between cooling water and crystallizer wall, heat will be largely effected on
Transmit, or even the serious consequences such as mould deformation, bleed-out can be caused.
From the foregoing, it will be observed that the stability of crystallizer cooling water system is directly related to the safe operation of continuous casting and crystallizer uses
Service life, it is therefore necessary to improve the reliability of whole cooling water system, avoid cooling water from fluctuating, it is long-term to prevent that bleed-out from limiting production
The stability of operation.
Utility model content
The purpose of this utility model is to provide a kind of crystallizer cooling water system, which avoids cooling water
Fluctuation, it is therefore prevented that bleed-out limits the stability of production longtime running, and reliability is high.
Technical solution is used by the utility model：
A kind of crystallizer cooling water system, including the circulation line connected with crystallizer, the inlet pipeline of circulation line by
Pump pressurization, water return pipeline are cooled down by heat exchanger, and inlet pipeline and/or water return pipeline are equipped with accumulator, and water return pipeline is equipped with
Flow control valve.
Further, water return pipeline is equipped with pressure sensor and temperature sensor.
Further, the connecting line of circulation line and accumulator is equipped with maintenance valve.
Further, accumulator dischargeable capacity is 10-100L, design pressure 0.3-2.5Mpa.
The beneficial effects of the utility model are：
During cooling water system normal operation, by Flux Valve Control flow, during cooling water system job insecurity, when
When system line pressures raise, cooling water enters accumulator accumulation of energy, until system line pressures no longer rise, when system pipeline pressure
When power declines, accumulator discharges energy, and cooling water is pressed into circuit, so that the decline of relieving system loine pressure.The cooling
Water system avoids the fluctuation of cooling water, it is therefore prevented that bleed-out limits the stability of production longtime running, and reliability is high.

Embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of crystallizer cooling water system, including the circulation line connected with crystallizer 4, circulation line
Inlet pipeline is cooled down by the pressurization of pump 1, water return pipeline by heat exchanger, and (the water inlet of accumulator 2 is equipped with inlet pipeline and water return pipeline
Pipeline and water return pipeline are formed by main pipe rail and bye-pass, and accumulator 2 may be provided on manifold, may also be arranged on branch pipe,
Certainly, in practical applications, accumulator 2 individually can be only set on inlet pipeline, can also only be set on water return pipeline
Accumulator 2), water return pipeline is equipped with flow control valve 7.
During cooling water system normal operation, flow is controlled by flow control valve 7, during cooling water system job insecurity,
When system line pressures raise, cooling water enters 2 accumulation of energy of accumulator, until system line pressures no longer rise, works as system pipes
When road pressure declines, accumulator 2 discharges energy, and cooling water is pressed into circuit, so that the decline of relieving system loine pressure.Should
Cooling water system avoids the fluctuation of cooling water, it is therefore prevented that bleed-out limits the stability of production longtime running, and reliability is high.
As shown in Figure 1, in the present embodiment, water return pipeline is equipped with pressure sensor 5 and temperature sensor 6.Pressure passes
Sensor 5 and temperature sensor 6 can monitor the pressure and temperature of cooling water at any time, control flow to provide ginseng for flow control valve 7
Examine.
As shown in Figure 1, in the present embodiment, the connecting line of circulation line and accumulator 2 is equipped with maintenance valve 3.
2 dischargeable capacity scope of accumulator is 10-100L, and design pressure scope is 0.3-2.5Mpa, specifically in the present embodiment
In, sheet billet continuous casting production 1500 × 200mm strands, cooling water system passes through to wide, the leaving water temperature of leptoprosopy branch, flow survey
Amount, the measurement of 4 total inflow temperature of crystallizer, control crystallizer 4 is wide, pneumatic control valve of leptoprosopy circuit adjusts cooling water inflow,
The setting value of technological requirement is automatically achieved, cooling water pressure 1.2Mpa, the effect volume of accumulator 2 is 30L, design pressure is
1.6Mpa。
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of the appended claims for the utility model.
