Description
Technical field
The utility model relates to a kind of device of rolled plate, especially relates to a kind of for the rolling cooling device of Aluminum Alloy Plate differential temperature.
Background technology
Water is the most cheap alloy element, and adopting rational cooling technology will be the most promising and technology benefit to the quality that promotes rolled plate.
Water spray cooling controlled rolling board quality TMCP (thermo-mechanical control process) has relatively ripe application in the iron and steel technology.Nineteen sixty-five, the strip mill that the pittsburgh,U.S.A city is 2286 has carried out control cooling experiment to the slab of 25.4mm.1980, Japanese Fushan factory built up first online steel plate cooling device (OLAC).1998, area, JFE west Japan iron processed institute Fushan (former NKK Fushan factory) Thick Plate Plant adopted the novel acceleration cooling system of so-called Super-OLAC (Super On-Line Accelerated Cooling).Its maximum characteristics are to have avoided transition boiling and film boiling, have realized comprehensive nuclear boiling, have the cooldown rate that can reach limit cooling and high cooling uniformity.The nozzle of the upper cooling system of Super-OLAC and the close together of steel plate, along rolling direction the water of certain pressure is ejected into the plate face with certain angle, the air film that forms between the remaining water of plate face and the steel plate is purged, thereby reach fully contact between steel plate and the cooling water, realize nuclear boiling.2003, a unique in the world cover cut deal online Equipment for Heating Processing-Hop installed at present in Japanese Fushan factory, was up to now the most advanced On-line Control cooling and the equipment of heating.The Hop system is installed on after the straightener, as shown in Figure 1.In order to improve the efficiency of heating surface, simplification device adopts huge induction coil, can carry out to steel plate the heating of two-forty.HOP and Super-OLAC combine, and can change flexibly on the roll line pattern of cooling, heating, can be according to needs Design and implementation freely, and the free degree of organizational controls significantly increases.
Also have in the application of spraying cooling controlled rolling board quality in aluminum alloy rolled, adopt emulsion cooling roll such as quenching unit at the bottom of the Continuous Roller of solution heat treatment and in the operation of rolling.These technology all in the plate rolling process and rollingly just take after complete, there is not yet and just adopt heat treatment mode before rolling.
China's present Main Problems of high-performance aluminium alloy cut deal material is that combination property and uniformity can not meet design requirement.In the production, the ultra-high-strength aluminum alloy slab is difficult to deeply inside in the distortion of rolling starting stage, causes the structure property of surface and heart section seriously inhomogeneous.At present, can not rolling for aluminum alloy ultra-thick plate, Adopts measure has: increase rolling roller diameter; Increase rolling single pass drafts; Adopting the Asymmetric Rolling technology is the rolling method of imperial shape.But be subjected to the restriction of manufacturing technology, the now increase of the drafts of the size of milling train and single pass has been difficult to break through, and existing modifying rolling mill Cheng Long shape milling train is also very unrealistic.
The utility model content
The utility model provides a kind of for the rolling cooling device of Aluminum Alloy Plate differential temperature, it mainly is to solve the distortion of the existing ultra-high-strength aluminum alloy slab of prior art in the rolling starting stage to be difficult to deeply inner, cause surface and the structure property of heart section seriously inhomogeneous, and the increase of the drafts of the size of milling train and single pass has been difficult to the technical problem of breakthrough etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Of the present utility model a kind of for the rolling cooling device of Aluminum Alloy Plate differential temperature, comprise roller-way, the upper and lower of described roller-way is equipped with spray equipment, spray equipment includes support, support is provided with a plurality of nozzles, nozzle and vertical direction are 10-20 ° inclination angle, take the rolling direction central plane of Aluminum Alloy Plate as the plane of symmetry, tilt to sheet material edge respectively.
The utility model all increases a cooling device before and after the cut deal reversable mill, after aluminium alloy flat bloom heats through homogenising, arrive the cooling device part through rollgang, cooling device sprays a large amount of emulsion cooling aluminium alloy cast ingots, make ingot casting produce certain thermograde in short transverse, skin temperature reduces rapidly, heart section keeps the condition of high temperature, because alloy all has hardening at subcritical temerature, the characteristic of hot mastication, therefore the ingot casting of this state enters after the milling train, and areal deformation is difficult, the middle part distortion is rolled not saturating problem easily when having overcome traditional Medium and Heavy Plate Rolling.Simultaneously, sheet material is after supercooling, and surface temperature is lower than recrystallization temperature, can not produce dynamic recrystallization in the operation of rolling, has some cold rolling advantages concurrently, and is good such as surface quality, the glossiness advantages of higher.The above aluminum alloy ultra-thick plate of sheet material, the especially 50mm that produces by the utility model is than even with produced in conventional processes hot rolled plate structure property out, and surface quality is high.
Be equipped with up and down spray cooling device at rolling-mill housing front and back, roller-way, this device is regulated and control water spray craft by the speed that changes roller-way, the switching of nozzle, pressure and the flow of injection.The roller-way in spray district is different from the roller-way that does not spray the district on the milling train, and this roller-way adopts stainless steel brush roll, has increased to greatest extent the spray area of lower surface, does not substantially have the spray dead point.The spray medium is selected emulsion.
As preferably, the described support that is positioned at the spray equipment of roller-way top is provided with the hydraulic cylinder that it is swung up and down.Upper spray cooling device is a head, adopts a hydraulic cylinder to support, and as required lifting is so that at ordinary times maintenance.
As preferably, described nozzle becomes arranged in arrays, and the adjacent column nozzle is symmetrical arranged mutually.Nozzle and vertical direction are 15 ° inclination angle, take the rolling direction central plane as the plane of symmetry, tilt to sheet material edge respectively, be conducive to like this by the kinetic energy of spray medium take away the slab remained on surface by the warmed-up medium of sheet material.
Therefore, the utility model makes the plate surface hardening by cooling, and the center hot mastication is realized surperficial and heart section rolls simultaneously, and it is even to produce structure property, and the Aluminum Alloy Plate of surface-brightening is simple and reasonable for structure.
