Description
Technical field
The present invention relates to the cooling technology field of hot-strip, be specifically related to a kind of superpower cooling device.
Background technology
Improving the performance of rolled piece by controlling roller repairing, is the effective way of hot-rolled product exploitation.Cooling facility for laminar flow and superpower cooling device is mainly relied on as being with the cooling of steel at present for rolling rear product.And think gauge pipe line steel (as X80 etc.) and the high-strength steel grade of part (as DP, MP, MS etc.) being needed to the cooling of more high strength, cooling facility for laminar flow can not meet the demands, and therefore needs to adopt superpower cooling device to cool.
During cooling device work, be generally supplied water to cooling device by supply-water pump.When band steel needs to cool, cooling device is opened, and after band steel has cooled, cooling device needs to close.Cooling device can pass through the frequent opening and closing of valve, but the supply-water pump of correspondence but can not frequent like this opening and closing, so all cooling devices all need to solve the flexible control problem of contradiction between the continuous unlatching of supply-water pump and the discontinuous water-spraying control of band steel and spray water tank.
The cooling length of cooling facility for laminar flow about 40 meters, flow 4200m3/h, water pressure is 0.07Mpa, can control the opening and closing often organizing spray water tank flexibly.Because cooling facility for laminar flow pressure of supply water is lower, generally by supply-water pump, cooling water is beaten to elevated tank, then supplied water to cooling device by elevated tank; When laminar cooling system does not need cooling, supply-water pump still to high-level tank water, but is equipped with overflow passage on elevated tank, and unnecessary water overflow is walked, and the operation and maintenance of whole cooling device is simple comparatively speaking.
The cooling capacity of superpower cooling device is very strong, and relatively very short (being generally only between 7-10 rice), as 1780mm hot rolling line, superpower cooling system cooling zone length only 7 meters, the cooling water inflow of system is 7000mm to the maximum to cooling zone length
3/ h.Like this, be subject to the restriction of self space, superpower cooling device flexible control can not often organize opening and closing and the Flow-rate adjustment of spray water tank as common cooling facility for laminar flow, and cooldown rate and the chilling temperature precision of whole device all can reduce.Further, in order to improve the heat exchange efficiency of cooling water, the more common section cooling of cooling water pressure of superpower cooling is compared much bigger, and general cooling water pressure is 0.5Mpa, is obviously now unpractiaca by the form of elevated tank overflow.Some superpower cooling device has been installed and has been held pressure relief valve on its water main, and like this when cooling device does not need water-spraying control, supply-water pump is not also shut down, and its unnecessary cooling water is let out to rolling line slag runner by holding pressure relief valve.But, in actual applications, find that the drawback done like this is very large, reason is exactly because cooling water pressure is higher, flow is also very large simultaneously, holding pressure relief valve when arranging cooling water, can produce very large vibrations, plant running is very unstable, simultaneously very unfavorable to the maintenance of its plant equipment and electrical instrumentation.Therefore, be necessary to improve prior art.
