Definitions

  • This invention relates to an apparatus for the high current density electrotreating (pickling. cleaning. etc.) of metal strip and is more particularly related to improvements in electrode positioning and construction.
  • FIGURE is a diagrammatic representation of a longitudinal cross-section of the apparatus, illustrating the essential features of this invention.
  • the apparatus consists of a tank 2, containing an electrolyte (not shown) suitable for the contemplated electrolytic treatment.
  • the metal strip 3 is passed in a substantially horizontal plane, through non-conductive bumper rolls 4a, into the tank and between electrode pair configurations 5a 5b, 6a 6b, and 7a 7b. respectively.
  • the electrodes are oriented in a conventional electrotreating position; that is. their longitudinal axes (1') lie in a segment of a plane which is parallel to the plane segment formed by the strip face and (ii) are generally perpendicular to the direction of strip travel.
  • the strip On exiting the tank, the strip is again passed through bumper rolls 4b, placed somewhat closer to the strip than the electrodes themselves.
  • bumper rolls which also act as guide rolls, serve to prevent undesirable contact of the strip with the electrodes. Their use is especially desirable in commercial practice, where a high rate of strip travel (increased vibration) and poor strip shape (waviness) would both combine to make such undesirable contact a virtual certainty.
  • Plastic pipe bumpers 8 may also be placed within the tank to provide additional insurance against such undesirable contact.
  • the deleterious effects of stray currents are to a substantial extent eliminated, thereby further reducing the tendency to arcing and/or strip burns, attendant in the use of very high current densities.
  • the portion of the electrodes facing the top surface of the strip exhibit a convex shape and preferably be of a generally semicircular shape.
  • the portion of the electrodes not facing the strip i.e., the top portions of electrodes 5a, 6a and 7a may, for example, be flat.
  • the shape of the bottom electrodes is not critical and conventional electrodes of rectangular cross-section may be employed. In actual practice a large number of electrodes will be produced at one time. In order that the electrodes may be interchangeable it will generally be preferable to employ bottom electrodes 5b, 6b, 7b which are similarly of a generally cylindrical shape.
  • top electrode 5a does not overlie electrode 5b. It has been found that additional enhancement of efficiency may be achieved if the electrodes forming a pair configuration do not so overlie one another. Stated another way, if we imagine a vertical axis drawn through both the top and bottom electrodes, then the distance between these two axes should be greater than the sum of the cross-sectional widths of both electrodes, divided by 2. In the specific case where round electrodes are employed, then the distance between the vertical axes should be greater than: the sum of the diameters of both electrodes divided by 2 (i.e. greater than the sum of the two radii). The beneficial effect of such electrode offset is shown in Table II. Unless otherwise stated, electrolyzing conditions were the same as above. However, utilizing the knowledge gleaned from the data of Table I, only round electrodes were evaluated in the runs below.
  • baffles 9 Separating the respective electrode pair configurations are insulative baffles 9 for directing the current through the strip.
  • These bafiles which may, for example, be made of polypropylene, are positioned a short distance from the strip surface, but nevertheless sufficient so that the passage of the strip therethrough is not encumbered. Since a significant portion of the current would tend to travel in a straight line between the electrodes (eg. a line between 5a and 6a) it may be seen that the baffles serve to block that route, and force that otherwise lost current through the strip. It is therefore desirable that the baffles be sufficiently close to the strip so as to cause a substantial portion of the current which would normally travel in such straight lines, to be diverted therefrom and travel through the strip (see the dashed lines of the FIGURE).
  • An apparatus for the electrolytic treatment of metal strip within an electrolyte bath comprising:
  • n a number, n, of electrode pair configurations, n being at least 2, in which the electrodes forming each of said pairs are,
  • a d-c source of EMF adapted to supply a current density within the range of 500 to 10,000 Amps/ft to said strip, and connected so as to make the electrodes in each pair approximately the same potential and of a polarity opposite to that of the pair configurations adjacent thereto;
