Description
Technical field
The utility model belongs to the technical field that hot rolled steel plate production line supplies water, and particularly relates to a kind of medium plate cooling after rolling system.
Background technology
On hot rolled steel plate production line, in order to improve the quality of products, increasing Heavy Plate Production line is configured with the after-rolling cooling system that superpower cooling system and Controlled cooling system constitute jointly.Different steel grade has different requirements to process for cooling.In order to realize the cooling requirement of different steel grade more flexibly, superpower cooling device generally has two kinds of patterns, high pressure mode and low-voltage, when superpower cooling system adopts high pressure mode, provides cooling water by supporting variable frequency pump; When superpower cooling system adopts low-voltage, need additional low-lift pump group, add equipment cost, also can be supplied water by the general pump of Controlled cooling system, need the water consumption considering superpower cooling device like this, add the investment of pump group and pump house floor space.
Summary of the invention
The object of the utility model patented technology is to provide a kind of medium plate cooling after rolling system, can meet the cooling requirement of different steel grade, save equipment investment simultaneously.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of medium plate cooling after rolling system, comprise superpower cooling system and Controlled cooling system, described superpower cooling system comprises the variable frequency pump and superpower cooling device that are connected by pipeline, described Controlled cooling system comprises controlled cooling model device, general pump and elevated tank, described general pump is connected by the import of pipeline with described elevated tank, the outlet of elevated tank is connected with superpower cooling device with described controlled cooling model device respectively by pipeline, the pipeline that described elevated tank is connected with superpower cooling device is provided with the first valve, it is characterized in that, the pipeline that described variable frequency pump is connected with superpower cooling device is provided with the second valve, variable frequency pump is connected by pipeline with the import of described elevated tank, the pipeline that elevated tank is connected with variable frequency pump is provided with the 3rd valve.
By such scheme, described first valve, the second valve and the 3rd valve are operated pneumatic valve.
The beneficial effects of the utility model are: provide a kind of medium plate cooling after rolling system, when superpower cooling device and controlled cooling model device all use low-pressure water, by general pump and variable frequency pump simultaneously to high-level tank water, save the investment of pump group, pump house floor space is little, adds the flexibility that pump group regulates.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Wherein: 1. controlled cooling model device, 2. superpower cooling device, 3. elevated tank, 4. the first valve, 5. the second valve, 6. the 3rd valve, 7. general pump, 8. variable frequency pump.
Detailed description of the invention
For understanding the utility model better, below in conjunction with drawings and Examples, the utility model will be further described.
As shown in Figure 1, a kind of medium plate cooling after rolling system, comprise superpower cooling system and Controlled cooling system, superpower cooling system comprises the variable frequency pump 8 and superpower cooling device 2 that are connected by pipeline, Controlled cooling system comprises controlled cooling model device 1, general pump 7 and elevated tank 3, general pump 7 is connected by the import of pipeline with elevated tank 3, the outlet of elevated tank is connected with superpower cooling device 2 with controlled cooling model device 1 respectively by pipeline, the pipeline that elevated tank is connected with superpower cooling device is provided with the first valve 4, the pipeline that variable frequency pump is connected with superpower cooling device is provided with the second valve 5, the import of elevated tank is connected by pipeline with variable frequency pump, the pipeline that elevated tank is connected with variable frequency pump is provided with the 3rd valve 6, first valve 4, second valve 5 and the 3rd valve 6 are operated pneumatic valve.
Controlled cooling model device 1 is lower with water hydraulic pressure, and General Requirements is 0.2Mpa.In order to the continuity of the stability and water supply that ensure hydraulic pressure, controlled cooling model device is generally supplied water to elevated tank 3 by general pump 7, then is supplied water to controlled cooling model device by elevated tank.
Superpower cooling device 2 is higher with water hydraulic pressure, and be generally 0.5Mpa, so superpower cooling device is directly supplied water by variable frequency pump 8, now the 3rd valve 6 is closed, and the second valve 5 is opened.According to the difference of producing steel grade, in actual production, do not need superpower cooling device water under high pressure to cool, and need by superpower cooling device low-pressure water water cooling.In this case, the 3rd valve 6 is opened, and the second valve 5 is closed, and is supplied water simultaneously, open the first valve 4 simultaneously, supplied water by elevated tank to controlled cooling model device 1 and superpower cooling device 2 by variable frequency pump 8 and general pump 7 to elevated tank 3.
