Method and apparatus for meniscus coating one or two sides of steel strip (34) with a metal or metal alloy. The apparatus includes a horizontally disposed coating tray (50, 52) for containing molten coating metal, means (46) for maintaining the temperature of the coating metal above the melting point of the coating metal, means for moving steel strip transversely past a departure lip positioned on one side of the coating tray (50, 52) and means for maintaining the level of the coating metal in the coating tray (50, 52) relative to the upper elevation of the departure lip so that an uninterrupted flow of the coating metal can be delivered over the departure lip to a surface of the strip (34). The coating tray (50, 52) may be rotatably mounted for adjusting the level of molten metal in the coating tray. The coating tray (50, 52) also may include means for lateral displacement for positioning the departure lip a predetermined distance away from the strip (34). The terminal end of the departure lip preferably includes a planar upper surface having an acute angle of at least 15 DEG relative to the horizontal plane of the coating tray. Non-oxidizing gas may be passed through a jet nozzle (42, 44) to control the coating thickness on the strip (34A). <IMAGE> |
