Description
Technical field
The utility model relates to the milling train technical field, particularly a kind of rolled piece homogeneous cooling apparatus.
Background technology
In hot rolling iron and steel, non-ferrous metal field, the form of cooling device has a variety of, for example laminar flow cooling, reinforced cooling, aerosol cooling or the like.And use through the cooling device form that multi-form nozzle is housed on the cooling medium pipe the most extensive, the cooling facility for laminar flow of hot-strip, hot rolled steel plate for example.
In the production process in fields such as hot rolling iron and steel, non-ferrous metal, at the width of rolled piece, the problem of non-uniform of temperature is inevitable; In cooling procedure subsequently, because cooling water flows freely on the rolled piece surface, the water at the rolled piece middle part rolled piece limit portion that need flow through discharges; The intensity of cooling that makes rolled piece limit portion causes the excessive temperature differentials of rolled piece middle part and rolled piece limit portion, under some operating mode greater than the rolled piece middle part; Can reach more than 100 ℃, the problem of non-uniform of temperature is further aggravated, therefore; Take place because the inequality of rolled piece temperature causes the inhomogeneous of properties of product through regular meeting, caused the product degradation to sell, even scrapped; Reduced the lumber recovery of product, increased production cost, and the plate shape of product, performance etc. have been produced very big harmful effect.
Prior art has multiple mode to solve, improve the middle part in the rolled piece cooling procedure, the problem of limit portion excessive temperature differentials.
Publication number is 201046471 Chinese utility model patent " a kind of edge-masking device " (patent No.: disclose a kind of radical occlusion device 200720100874.X); This device comprises devices such as swing arm, baffle plate, connecting rod; Through the length variations of connecting rod regulate two side shields to moderate; Thereby realize that edge dam is in best cooling water and blocks the position, obtain the best width that blocks, thereby reach the problem of the excessive temperature differentials that improves rolled piece center and limit portion.Since this technology be cooling water water conservancy diversion with limit portion outside rolled piece, caused the waste of laminar flow water, be unfavorable for energy efficient, improved production cost; This technology only relates to the last spray apparatus of laminar flow cooling, does not relate to other parts, and it is of limited application.
Publication number is 201423388 Chinese utility model patent " a kind of laminar flow cooling is the spray apparatus down " (patent No.: 200920069198.3) disclose a kind of spray apparatus down; This device comprises devices such as positioning seat, slide block, baffle plate; Through regulating the channel width of cooling water, reduce the temperature drop of strip edge portion.Cover though this technology is the cooling water with limit portion, can practice thrift the part cooling water, still have the part cooling water to be gone out, can cause the waste of laminar flow water equally, be unfavorable for energy efficient, improved production cost by water conservancy diversion; This technology only relates to the following spray apparatus of laminar flow cooling, does not relate to other parts, and it is of limited application.
Publication number is 201357174 Chinese utility model patent " a kind of laminar flow stage cooling device " (patent No.: disclose a kind of cooling device 200920068019.4); This device comprises devices such as deciding standpipe, dividing plate; Pass through dividing plate; Foundation realizes the laminar flow cooled region in the width respective change corresponding to the slit laminar flow of band channel width, thereby reduces the temperature drop of strip edge portion.In actual production, this technology can't play the purpose that improves cooling uniformity when steel plate/belt steel sideslip, and this technology can't guarantee that cooling water is not excessive under the unstable situation of hydraulic pressure.
Because laminar flow cooling is that the upper and lower surface of rolled piece is cooled off simultaneously, and between each cooling section, is provided with devices such as side-spraying device or top spray apparatus, therefore, more than the common issue with that exists of technology be:
1. do not take all factors into consideration the solution that goes up spray apparatus, following spray apparatus, side-spraying device, the versatility of technology is poor, restricted application.
2. fundamentally do not solve the problem of waste laminar cooling water, be unfavorable for energy efficient, increased production cost.
