Abstract: The invention includes a vessel (24) for containing a bath (28) of molten coating metal such as zinc, a sink roll (30) submerged into the bath defining a path of travel for a metal strip (12) through the bath with the strip applying force to the roll as a result of tensile load on the strip and a pair of stabilizing rolls (32). Sink roll (30) is supported by a pair of spaced arms (36) and each stabilizing roll (32)is supported by a pair of spaced arms (44). Each roll has a cylindrical body (52) having an outer surface for being in contact with strip (12) and a trunnion (54) projecting axially from each end of the roll body. Each arm (36) has an upper end (38) and a lower end (40), the upper ends being mounted at positions (42) above the vessel and the lower ends for being submerged into the bath. Each lower end of the arms includes means (58) for supporting the roll and means (56) for restraining lateral thrust of the roll.

Abstract: A shallow vessel (50,52) for being horizontally disposed when containing a molten metal or metal alloy (66) for meniscus coating one side of a clean metal strip (34A) when the strip is moved vertically past one side of the vessel. The vessel includes a shell (68) such as austenitic stainless steel, a refractory lining (70), a molten metal departure lip (72) mounted on the upper surface of the side of the vessel, a spirally shaped induction coil (64) for maintaining the molten metal above its melting point and a flux concentrator (74). The induction coil is positioned below the refractory lining and the flux concentrator is positioned below the induction coil. The induction coil and the flux concentrator underlie the area occupied by the molten metal.

Abstract: Method and apparatus for meniscus coating one or two sides of steel strip with a metal or metal alloy. The apparatus includes a horizontally disposed coating tray for containing molten coating metal, gas heaters for maintaining the temperature of the coating metal above the melting point of the coating metal, stabilizing rollers for moving steel strip transversely past a departure lip positioned on one side of the coating tray and adding solid or molten metal to the coating tray for maintaining the level of the coating metal in the coating tray 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. The coating tray may be rotatably mounted for adjusting the level of molten metal in the coating tray. The coating tray also may include a sled for lateral displacement for positioning the departure lip a predetermined distance away from the strip.

Abstract: A process for magnesium desulfurization of ferrous metal melts in a vessel comprising the provision of a fluid, high sulfur capacity slag wherein the weight ratio of slag constituents associated with sulfur to slag constituents associated with oxygen is greater than 0.8, followed by addition of magnesium to the melt in an amount sufficient to combine with the sulfur in the melt, transfer to the sulfur removed by the magnesium addition to the slag, and retention of the removed sulfur in the slag, thereby improving magnesium desulfurization efficiency and substantially eliminating sulfur reversion from the slag back to the melt.
