Description
Technical field
The utility model relates to steel plate rolling technical field, has particularly related to a kind of super large reduction ratio and has lubricated by force cold-strip steel spray beam device and rolling mill.
Background technology
Can produce a large amount of heats with steel in the process of rolling, these heats make roll can produce uneven thermal expansion when rolling, form roller heat convex degree learning, thus affect template.Therefore, in the operation of rolling, need to take away by adopting emulsified liquid injection gear to spray emulsion the heat produced in the operation of rolling, the internal stress of release working roll is to improve the life-span of roll, reduce the surface of the friction between band steel and roll and between roll and roll, simultaneously cleaning band steel and roll, thus improve fineness and the template of belt steel surface.
Spray beam device is the longest emulsified liquid injection gear used in belt steel rolling process.Spray beam device mainly comprises brace summer and nozzle, and wherein nozzle is fixedly assemblied on brace summer, and during use, emulsion sprays to the roller of rolling mill by nozzle, thus cools it and clean.Due in belt steel rolling process, the maximum position of caloric value is at the contact position place of working roll with band steel, therefore the nozzle of existing spray beam device is all only towards the working roll of rolling mill and the contact position of band steel, the i.e. Roll-gap position place of double-working, and in fact, in belt steel rolling process, intensification region is not only present in the position that working roll contacts with the strip, the first half in the latter half in top working roll radial direction and bottom working roll radial direction is in fact all can the region of rapid temperature increases, only spraying emulsion to the roll gap place of working roll is can not well play to prevent working roll from producing the problem of uneven thermal expansion, especially when processing super large reduction ratio strength strip steel, the problems referred to above are particularly outstanding.
Notification number is that the Chinese patent of CN 201815544 U discloses a kind of section cooling device for working rolls, the scheme of spraying emulsion to the middle part of working roll and roll gap place is respectively disclosed in the description of this patent, but, it is arrange respectively (the 11st section, description and Figure of description) for spraying the spray beam device of emulsion to the middle part of working roll and roll gap place, this obviously needs to use a lot of spray beam devices, it is the cost that can increase steel rolling equipment, in addition, owing to being the spray beam device arranged respectively, therefore need to locate respectively each spray beam when installation, therefore very inconvenient to the installation of spray beam device, working strength is larger, and in fact for same working roll, intermediate position and Roll-gap position are relatively-stationary, if it is later relative fixing to adjust angle for the middle part of spraying cold same working roll and the nozzle of the two spray beam devices at roll gap position, then can realize once mounting spray beam device can to the effect of Liquid injection cooling while of the middle part of working roll and roll gap position.In view of this, what introduce in above-mentioned patent specification is obviously unscientific by installing that more spray beam devices cool working roll additional, belt steel rolling equipment need a kind of cost lower, be more convenient to the cooling system installed.
