Abstract
1,222,198. Coating ferrous metal with zinc. JONES & LAUGHLIN STEEL CORP. June 26, 1969 [June 28, 1968], No.32304/69. Heading C7F. Ferrous substrate coated with Zn by passing it into an evacuated chamber having a pressure less than 10<SP>-3</SP> torr, wire brushing said substrate in said chamber sufficiently to cold work and deform the substrate surface and activate it, vapour depositing zinc on to the brushed surface and maintaining the final substrate temperature above about 375‹F. Steel strip 1 passes from uncoiling reel 3 through pickling, degreasing, washing and drying system 14 into vacuum chamber 2 at a speed which may exceed 200ft/min. Rotary wire brush 11, acting in the opposite direction to the strip and against counter-roll 12 activates the strip by removing at least 2 x 10<SP>-4</SP> 1b/sq. ft of steel into hopper 13, and the strip passes over crucible 5 containing liquid zinc 6 so that vapour 7 may coat the surface. An electron beam heater 9, in conjunction with thermocouple 10, regulates the strip temperature above 375‹ F., preferably between 450‹ F. and the re-evaporation temperature of the zinc. The heater may precede the vapour source if required.
