Abstract
797,713. Coating apparatus. UNITED STATES STEEL CORPORATION. May 31, 1956, No. 16913/56. Class 140. A thin controllable film of lubricant is deposited on a metallic strip by passing the strip centrally between spaced-apart electrodes extending transversely thereof and electrically interconnected at their ends to form a loop, impressing a high D.C. potential across said loop and strip, dispersing lubricant in a steam of gas, and introducing the dispersed lubricant out of contact with the electrodes into the zone of maximum electrostatic intensity in the space between the strip and the transversely extending electrodes. Oils such as palm oil may be used as lubricants. As shown, the strip 2 passes round deflector roll 4 and into chamber 6 which consists of a steel outer shell 10 and an inner shell 12 of, for example, a phenolic resin insulating material. Within the shell 12, one on either side of strip 2, are a pair of metal grid frames of inverted U-shape, supported by and electrically insulated from the outer shell 10. U-shaped steel frames 14 each carry one or more vertically spaced wires 18 strung between the frame legs and opposed legs of the frames are electrically connected by metal bars 20. A high potential D.C. source 22 is connected between the frames 14 and the strip through conductor-deflector roll 8 mounted on the shell. Roll 8 can be provided with a collector ring and connected directly to the source. Spray heads 30 are connected to atomizers 32 dipping in oil reservoirs 36 made of glass and located outside chamber 6. The connecting pipes and spray heads are of non-conducting phenolic resin material. Heads 30 contain a series of outlets 38 aligned along the length of the heads. Atomization is assisted by heating lamps 46 focused on reservoirs 36 and may be varied by regulating the atomizing gas pressure. Oiling may be conducted as a separate operation or the apparatus may be incorporated in existing strip processing lines.
