Abstract
The utility model discloses a rolling-mill roller-box type sectional cooling device, which is applied to a plate and strip rolling mill with large rolled-piece heat-conduction coefficient. The rolling mill comprises an upper working roller and a bearing seat and is characterized in that the bearing seat is movably connected with a sectional water-supply box through a rotary shaft, the sectional water-supply box is symmetrically distributed in the shape like a Chinese character 'ba' at the inclined upper part of the upper working roller, a quick-change joint is arranged at the upper end of the sectional water-supply box, nozzles are arranged in the middle of the sectional water-supply box, a collecting box is arranged at the lower part of the sectional water-supply box, a pressure roller is arranged at the lower part of the collecting box, and the working surface of the pressure roller is freely laminated with the working surface of the upper working roller and supported on the end plate of the sectional water-supply box; and each nozzle is divided into an I section, a II section, a III section and a IV section along the length direction of the working roller, and each section is connected with a flow collecting pipe with a control valve, wherein the number of the nozzles is configured as specified. The device adopts a two-stage recovering device, has the function of sectional cooling, not only solves the problem of roller cooling, but also better solves the isolation problem of a cooling fluid and a rolled piece, realizes the coarse adjustment for the thermal camber of the roller and obtains better plate shapes.
Description
Technical field
The utility model relates to lubricating, cool off or heating of roll, relates in particular to the external refrigeration of the big sheet strip hot rolling mill of rolled piece thermal conductivity factor to top working roll.
Background technology
In the rolling field of non-ferrous metal, the big milling train of especially rolling rolled piece thermal conductivity factor reduces cooling fluid as much as possible when need cool off topping roll and is ejected on the rolled piece at present.Milling train top roll cooling device structure as shown in Figure 3 in the past.This cooling device is directly cooling fluid to be ejected into the top working roll surface by spray beam, and this device flows to the roll both sides after also having adopted pressure roller cooling fluid can be collected simultaneously.In fact this cooling device that has added pressure roller also is difficult to both sides are all blocked and flowed to cooling fluid, and the position that cooling fluid is ejected into roller surface is also relatively by last, and cooling effect is also bad.Simultaneously, this device does not possess the segmentation refrigerating function yet, and the coarse adjustment that can not realize the hot convexity of breaker roll is to obtain plate shape preferably.Also have some milling trains to adopt pressure roller to reclaim in recent years, but effect neither be fine, and the recovery cross-sectional area of dash roller and roll formation is little, can not satisfies the recovery needs of big flow cooling fluid.
Summary of the invention
The purpose of this utility model is, proposes a kind of rolling mill roll box type stage cooling device, is intended to solve the cooling problem of the big non-ferrous metal rolled piece of thermal conductivity factor when rolling, to guarantee rolling quality.
Technical solution of the present utility model is achieved in that
A kind of rolling mill roll box type stage cooling device, comprise top working roll and bearing block thereof, it is characterized in that: the end face of described bearing block flexibly connects by gyroaxis and segmentation water supply box, described segmentation water supply box is the oblique upper that splayed is symmetrically arranged in top working roll, and there is hydraulic quick coupler its upper end, and there is nozzle at its middle part, there is the collection box its underpart, pressure roller is arranged at the bottom of collecting box, and the working face of pressure roller and the working face of top working roll are freely fitted, and are supported on the end plate of segmentation water supply box; Described nozzle is divided into I, II, III, IV section along the working roll length direction, and every section all is connected with the header that has control valve, and nozzle quantity wherein disposes in accordance with regulations.
Compared with prior art, advantage of the present utility model mainly shows:
The minimizing cooling fluid overflows to the rolling requirement on the rolled piece when 1, having realized the breaker roll cooling.
2, can carry out segmentation control to cooling fluid, realize the coarse adjustment of the hot convexity of breaker roll, and then obtain better plate shape.
3, can adapt to different roller footpaths automatically, after the top working roll surface is stained with metal fillings, open pressure roller automatically and prevent to damage cooling device, can automatically reset then.

The specific embodiment
Rolling mill roll box type stage cooling device shown in Fig. 1,2 and 4 mainly partly is made up of gyroaxis 1, hydraulic quick coupler 2, segmentation water supply box 3, nozzle 4, collection box 5 and pressure roller 6 etc.
This device links to each other with the roll chock of both sides by gyroaxis 1, the outside feed system of cooling fluid links to each other with hydraulic quick coupler 2, hydraulic quick coupler 2 is supplied with segmentation water supply box 3 with cooling fluid, nozzle 4 is installed on the segmentation water supply box 3, nozzle 4 sprays to the cooling fluid on top working roll surface and carries out first order recovery by collecting box 5, and by the orifice flow of both sides to the roll both sides, collecting box 5 and 7 cooling fluids of overflowing of top working roll by the applying realization second level recovery of pressure roller 6, and flowing to the both sides of top working roll 7 with top working roll 7.This device is by the position of appropriate design gyroaxis 1, and realize by the gravity effect make pressure roller 6 tightly fit to top working roll 7 surfaces, can be fit to different roller footpaths, and can after being stained with metal fillings, top working roll 7 surfaces open automatically, prevent to damage cooling device, be stained with the metal fillings position by after can also automatically reset by gravity.
The fragmentation feature of this rolling mill roll box type stage cooling device is by control valve 10 and segmentation water supply box 3 common realizations.Hop count according to technological requirement design segmentation water supply box 3 is I, II, III, IV ... and control valve 10A, B, C, the D of selection respective numbers ... by pipeline these control valves 10 are connected with segmentation water supply box 3 corresponding sections, can realize that the nozzle 4 in each control valve (10) control correspondent section carries out the sprinkling of cooling fluid.
