Definitions

  • This invention relates to a device for brushing and continuously lubricating rolling mill rolls for flat products rolled without pollution of said products by the lubricant used; it can be used for hot or cold rolling of metallurgical products, in particular for that of AI and its alloys.
  • Document FR-A-2 017 092 discloses a system for brushing rolling mill rolls in a closed enclosure, but in which the inlet 140, 140a of the evacuation pipes 142, 140 of the fluid is located at the lower level of enclosure 135a; therefore the brushes 122a, 123a do not bathe in the corresponding fluid, contrary to the object of the invention.
  • each of the cyclinders is applied, preferably on the outlet side, a generally rectangular enclosure open on one face, and therefore the two opposite sides, adjoining the opening, are limited by an arc of a circle whose radius is substantially equal to that of the working cylinders; the edge of the opening is provided with a continuous elastic peripheral seal.
  • Each of the enclosures is supported on the corresponding cylinder using pneumatic cylinders or any other equivalent means (spring, etc.). The enclosure, the cylinder and the corresponding peripheral seal thus delimit a closed and sealed space.
  • the brush axes receive the rotational movement in a known manner by a chain driven by a motor.
  • the entire transmission, coupled to the engine, is placed in a housing fitted with conventional seals.
  • the rolling lubricant is distributed, at the top and near the same generator of the cylinders, by one or more adjustments (for example 3: 1 central and 2 lateral). These adjustments ensure the watering of the working cylinder; the lubricant is then recovered from the bottom of the enclosures, from where it is taken up by a pump. Its level, determined by the height of the return pipe (s), is such that the brushes are immersed in it up to the vicinity of their axis of rotation.
  • the recovery is ensured, for example, by a positive displacement pump, so as to create a vacuum in the enclosure; in this way, accidental leakage of the lubricant on the product is avoided in the event of failure or local imperfection of the peripheral seal of the enclosure.
  • the cross section of the peripheral joint is of paramount importance. It has been determined that this, which is continuous, must have a convex cylindrical surface along the generatrices of the cylinder, and the corresponding toric surface along the two straight sections of the cylinder.
  • the product 1 engaged upstream of the working rolls 2a, 2b - diameter 600 mm - of a duo rolling mill comes out in the form of a laminated strip 3.
  • On the downstream side of the rolls there are two enclosures 4a, 4b which are supported on the cylinders by means of the peripheral seal 5 under the action of jacks (not shown).
  • In each of the enclosures there are two rotary brushes 6a, 6b made of 150 mm diameter steel, driven by an electric motor in the direction indicated by the arrows, at a speed of 750 rpm and which are pressed against the cylinders by two cylinders tires (not shown) pressing themselves on the rear wall of the enclosure.
  • nozzles 7a, 7b distributing the lubricating emulsion at the rate of 10 m 3 / hour.
  • the emulsion is taken up by the outlet pipes 8a, 8b.
  • the flow rate of the supply and return pumps (not shown) is adjusted so that the vacuum gauge 9a, 9b installed on the enclosure indicates a vacuum of 10 to 20 kPa.
  • the peripheral seal 5 used is a PER-BUNAN seal, the section and dimensions of which are given in FIG. 2.
