Description
Technical field
The invention belongs to rolling automatic control technology field, particularly relate to the water system of cut deal roller repairing device.
Background technology
Roller repairing device form conventional at present has ultra-fast cooling device and cooling facility for laminar flow etc., also has production line ultra-fast cooling device and cooling facility for laminar flow simultaneously configured.The configuration requirement of different cooling devices to water system is different.Cooling facility for laminar flow water pressure is lower, general employing high-level tank water, namely by supply-water pump group, water is delivered to elevated tank, cooling water in elevated tank is under the effect of deadweight, feed to cooling facility for laminar flow, so water supply process hydraulic pressure is more stable, adjust stream function because elevated tank possesses water storage, water utilizing process energy consumption is lower simultaneously.Ultra-fast cooling device be that the pressure of cooling water is higher by water feature, if adopt high-level tank water, one-time investment is comparatively large, adopts water pump directly to supply water so general.
Generally, factory is only equipped with a kind of cooling device of form, therefore relatively simple to the designing requirement of water system.Along with the development of technology, occurred the cooling device that ultrafast cold-peace section cooling configures simultaneously, due to demand that is different to the requirement of water system and production technology, generally need to configure supply-water pump group respectively, equipment investment is very large.
Summary of the invention
Object of the present invention is exactly for prior art Problems existing, there is provided a kind of water system parallel for ultrafast cold-peace section cooling dual system, this water system can meet ultra-fast cooling device and cooling facility for laminar flow and only adopt a set of supply-water pump group with water simultaneously.
Above-mentioned purpose is realized by following proposal:
A kind of water system parallel for ultrafast cold-peace section cooling dual system, it is characterized in that, described water system comprises water cooling pond, supply-water pump group, water main, elevated tank, high-level tank water pipe, control valve, open and close valve and cooling facility for laminar flow supply channel; The water inlet end of described supply-water pump group is connected to described water cooling pond, and the water side that described water main connects described supply-water pump group is connected to ultra-fast cooling device; Described elevated tank is connected on described water main by high-level tank water pipe; Described cooling facility for laminar flow supply channel connects described elevated tank and cooling facility for laminar flow.
According to above-mentioned water system, it is characterized in that, high-level tank water pipeline is provided with control valve, control valve is according to production technology demand determination opening degree, and ultrafast cold when being used alone, control valve opening degree is set as 0%; When section cooling is used alone, control valve opening degree is set as 100%; When ultrafast cold-peace section cooling uses, if section cooling average consumption is at 500m simultaneously
3/ below h, control valve opening degree is set as 10%, and section cooling average consumption is at 500 ~ 1000m
3time between/h, control valve opening degree is set as 15%.
Beneficial effect of the present invention: the process water requirement of the various operating mode such as the present invention utilizes same set of water system to meet ultrafastly coldly to be used alone, section cooling is used alone, ultrafast cold-peace section cooling uses simultaneously, has effectively saved water system investment.
Accompanying drawing explanation
Fig. 1 is the structural representation of water system of the present invention.
Detailed description of the invention
See Fig. 1, water cooling pond 1 of the present invention, supply-water pump group 2, water main 3, high-level tank water pipe 4, control valve 5, elevated tank 6, open and close valve 7, ultra-fast cooling device 8, cooling facility for laminar flow supply channel 9, cooling facility for laminar flow 10.The water inlet end of supply-water pump group 2 is connected to water cooling pond 1, be responsible for fetching water from water cooling pond 1 and deliver to elevated tank 6 or ultra-fast cooling device 8 by water main 3 after supply-water pump group 2 supercharging, high water tank feed pipe 4 is provided with control valve 5, for adjusting elevated tank 6 output, position after the elevated tank 6 of water main 3 (position namely after high-level tank water pipe 4 and water main junction) is provided with open and close valve 7, use for during ultrafast cold 8 maintenance, cooling water inside elevated tank 6 to use through cooling facility for laminar flow supply channel 9 supplying layer flow cooling device by conducting oneself with dignity.
Supply-water pump group 2 is full variable frequency pump group, and model is 24SH-9, Q=2850m
3/ h, H=75m, quantity 3; Elevated tank volume 100m
3.Maximum water demand when ultra-fast cooling device is used alone: hydraulic pressure 5bar, water yield 6500m
3/ h; Maximum water demand when cooling facility for laminar flow is used alone: hydraulic pressure 1bar, water yield 2500m
3/ h; When ultrafast cold-peace section cooling uses simultaneously, ultrafast cold water pressure 5bar, maximum amount of water 6000m
3/ h, section cooling hydraulic pressure 1bar, most flood 1500m
3/ h.The above water yield is limit water consumption when producing extreme kind or specification, and for general kind and specification, actual used water amount is much smaller than maximum water consumption.
During normal production, open and close valve 7 is often opened.When section cooling is used alone, control valve 5 opens to 100%, open a supply-water pump and can meet industrial water demand, most of current direction elevated tank in water main 3, only has a small part current direction ultra-fast cooling device 8, for nozzle from water-cooled, equipment from water-cooled, control system carries out the closed-loop control of elevated tank water level, elevated tank is provided with liquid level gauge detect high water tank.When elevated tank water level is lower, improve water pump frequency, when water level is higher, reduce water pump frequency.When ultrafast cold be used alone time, control valve 5 cuts out (being namely adjusted to 0%) (if section cooling has from water-cooled needs, control valve 5 can give suitable aperture 5 ~ 10%, cooling water is made to get to elevated tank), determine to open water pump number of units according to ultrafast cold process water requirement, control system carries out pressure closed loop according to ultrafast cold process requirements, and pressure detecting point is positioned at ultra-fast cooling device segregated collection pipe.When ultrafast cold-peace section cooling uses simultaneously, control valve 5 is opened to suitable aperture, determines to open water pump number of units according to process water requirement.Control system carries out pressure closed loop according to ultrafast cold process requirements.For Heavy Plate Production, the off time of ultra-fast cooling device and cooling facility for laminar flow was greater than the steel time, can utilize and open control valve 5 pairs of elevated tank moisturizings off time, avoid cistern water level lower than lower limit, the high-order minimum rate of water make-up requirement of control valve 5 aperture demand fulfillment.Minimum rate of water make-up=(maximum water consumption × use the water time)/monolithic steel plate rolling time, the above parameter of the steel plate for different size, kind is different, and therefore the aperture of control valve 5 is different.In general, if section cooling average consumption is at 500m
3/ below h, control valve opening degree is set as 10%, and section cooling average consumption is at 500 ~ 1000m
3time between/h, control valve opening degree is set as 15%.
