Abstract
The present invention relates to a device for continuously cleaning and lubricating rollers of a rolling mill for manufacturing rolled plates. The rolled products can not be polluted by used lubricant. The device can be used for hot rolling and cold rolling, and is particularly suitable for aluminum rolling and aluminum alloy rolling. The shape of the casing of the device is an ordinary parallelepiped with one open surface, and the edges of two opposite upper side surfaces, near an opening, are in a circular arc shape; the radius of the circular arc is almost equal to that of a roller. The casing is tightly clung to the roller through a continuous elastic ring seal pad. A rotary brush is arranged in the casing, and the casing is filled with the lubricant by cycling of the lubricant and is in a state of negative pressure.
Description
What the present invention relates to is continuous cleaning and the sliding device of production milled sheet with rolling mill roll, and employed lubricant does not pollute milled sheet; It can be used for the hot rolling of metallurgic product or cold rolling, is specially adapted to the rolling of aluminium and aluminium alloy.
As everyone knows, when hot rolling or cold rolling aluminium and aluminium alloy, the surface state of its product is subjected to the influence of the surface state and the lubricating condition of roll.Usually when rolling, because in the operation of rolling or processing procedure afterwards, in annealing process, be difficult to satisfactory owing to the residue of lubricant forms the surface state that stain makes product on product.These defectives are only carried out for a long time, wasteful cleaning and (or) extra process of degreasing (before heat treatment) eliminates.
US Patent No 4061010 disclosed Zha Fan lubricating rollers are by liquid is ejected on the roll that is arranged in a housing.Therefore but under this device situation, housing is not to be pressed on the roll, although have air to flow to outside housing in the housing by peripheral clearance, has lubricant and wanders on milling material, thereby form stain during the heat treatment behind face.
The object of the invention provides a kind of roll continuous cleaning and lubricating arrangement, and this device can solve above-mentioned problems of the prior art.
For convenience of description, suppose roll mandrel to being level, normal conditions also always like this.
On every roll, at outlet side, pressing the housing of the common parallelepiped shape that an one side opens, the edge, two opposite flanks of adjacent openings is circular arc, and the semidiameter of garden arc seldom equals the radius of work roll; The edge of opening is equipped with continuous elastic ring sealing gasket.Each housing is pressed on the corresponding roll by air pressure supporting or suitable other instrument (as spring etc.).Therefore, by housing, the space that its Gask-O-Seal and corresponding roll constitute be sealing with sealing.
In these lower part of frame, arrange two rotary brush (on each shell 1), brush parallels with work roll, and contacts with roll, and preferably these brushes are with the unidirectional continuous rotation of identical speed, with the switched in opposite of roll.
The axle of brush rotates by the chain that is driven by motor.Whole transmission device is connected on the motor, and this device is placed in the chest that seal washer commonly used is housed.In each housing, by 1 or several nozzle (for example 3,1 at center, 2 of sides), in the eminence of all rolls, the same bus place near roll distributes with lubricator rolling.These nozzles guarantee the splash system lubrication of work roll; Then, lubricant is recycled to the bottom of housing, by pump they is taken away, and liquid level determines that by the height of discharging tube (1 or several) liquid level can make brush be immersed near its pivot center in liquid.
Return liquid and guarantee, so that form negative pressure in the housing by displacement pump; Lubricant can drain on the product by accidental Vent when the ring packing of housing is lined with local damage or local imperfection is arranged with regard to avoiding like this.
Usually, the service condition (characteristic and speed that brush rotate, flow of lubricant, negative pressure) of two housings on roll all is the same.
The cross section of Gask-O-Seal has important effect.It is confirmed as continuous, should be post surface, protruding garden along the bus of roll, and two vertical cross-sections along roll are the corresponding annular cross section.
The housing breaker roll is sealed fully.
For understanding the present invention better, now, illustrate with figure by the following examples:
Fig. 1: the vertical section of device
Fig. 2: the cross sectional dimensions of sealing gasket
(2a, 2b) product of (diameter 600mm) arrival end rolls into rolling band (3) at last to enter the double-roll rolling mill work roll.(4a 4b) is positioned at the outlet side of roll, and under the effect of air pressure supporting (not shown), housing is pressed on the roll by Gask-O-Seal (5) for two housings.In each housing, and the steel rotating brush that two diameters are arranged is 150mm (6a, 6b), by motor drives, to press the arrow direction and rotate, its rotating speed is 750 rev/mins, be pressed on the roll by two air pressure supporting (not shown)s, air pressure is supported on the rear wall of housing.
With 10 meters
3/ hour speed supply with 3 nozzles of emulsus lubricant (7a 7b), be positioned at the upper part of housing.(8a 8b) reclaims emulsion, adjusts supply pump and reclaims the flow of pump (not shown), and (9a 9b) indicates the negative pressure of 10～20KPa so that be installed in vacuum meter on the housing by discharging tube.
Certainly, when roll wore and tore continuously, its diameter can reduce, and the radius of housing is adapted to the vary in diameter of roll roller, and variable quantity is 6mm.
The material of Gask-O-Seal (5) is a kind of acrylonitrile-butadiene rubber, and its vertical section and size are seen Fig. 2.
The sealing pad is gluedd joint by two sections straight line portioies and two fan-shaped parts and forms together.
In the present example, rolling condition is as follows:
-A5 bandwidth: 1000 millimeters
-mill speed (outlet): 50 meters/minute
-metal inlet temperature: 450 ℃
-import thickness: 7.5 millimeters
-exit thickness: 3 millimeters
