Abstract: An article of equipment intended to be submerged in molten zinc, molten aluminum and mixtures thereof, said article containing an alloy material comprised of: Percent Carbon 1.6-2.6 Chromium 15.0-30.0 Tungsten 10.0-30.0 Molybdenum 2.0-8.0 Iron 10.0-50.0 and including, vanadium, niobium, cobalt, boron, and manganese and being substantially free of silicon.

Abstract: A rotating shaft for pumping or degassing hydrogen from molten metal comprising a motor connected to the upper end of a hollow shaft. An impeller is connected to the lower end of the shaft in the molten metal. The shaft is telescopically housed within a heat resistant shield shaft. The shield is clamped in a state of longitudinal compression to prevent tensile forces from damaging the shield as the impeller is being rotated.

Abstract: An apparatus for moving a stream of molten metal in a bath of molten metal having a housing and steel alloy legs to prevent the housing from rising in the molten metal. The steel legs are protected by tubular shields made of a heat resistant material. The shields each has a lower end attached to the housing and has an inner diameter that is larger than the leg's outer diameter to accommodate the thermoexpansion of the leg. Inert gas is introduced in the space between the steel leg and the shield to form an oxygen-free environment around the leg.

Abstract: An apparatus for moving a stream of molten metal in a bath of molten metal having a pumping member, a pump housing, a power device, a connecting element to connect the power device to drive the pumping member in motion, and a shielding element rotatably mounted on the pump housing and drivingly connected to pumping member. The connecting element comprises a pumping shaft having an upper end connected to the power device, and a lower end drivingly connected to the shielding element to rotate the pumping member when the power device is actuated. The shaft and the shielding element have a first and a second coefficient of thermal expansion, respectively. The shaft is telescopically disposed in the shielding element out of contact with the molten metal and formed a chamber between the shaft and the shielding element sufficient to permit thermal expansion of the shaft without imposing a radial thermal stress on the shielding element.

Abstract: A gas jet-operated pump for removing dross from the surface of a bath of molten metal. The pump can be employed for delivering molten metal to the dross for diluting it or for removing it from a selected area.

Abstract: Apparatus for moving and degassing molten metal in a conduit by delivering a gas jet into the conduit in the same direction as the metal is moving, so the momentum of the gas jet pushes the metal along its path of motion.

Abstract: An article suitable for submergence in molten zinc, aluminum and aluminum/zinc melts. The article is formed of an alloy comprising from greater than 1.0% to less than 5.0% carbon; from greater to 10.0% to less than 30.0% chromium; from greater than or equal to 0.0% nickel to less than 30.0% nickel; from greater than 1.0% to less than 15.0% tungsten; from greater than 1.0% to less than 10.0% molybdenum; from greater than 0.0% to less than 10.0% vanadium; from greater than 0.0% to less than 10.0% niobium; from greater than 0.0% to less than 20.0% percent cobalt; from greater than 0.0% to less than 5.0% boron; from greater than 10.0% to less than 50.0% iron; from greater than or equal to 0.0% to less than or equal to 6.0% zirconium; from greater than 2 to less than 6.5% manganese; and from greater than or equal to 0.0% to less than 1.0% silicon.

Abstract: A jet column reactor apparatus for moving molten metal in a bath of such metal is formed with a monolithic refractory body.

Abstract: A method for making either a ringless annealing furnace roll or a furnace roll having a series of spaced ring for supporting a metal strip being removed from an annealing furnace. Each ring is centrifugally cast with an outer rim of a steel alloy that is relatively insoluble with respect to the alloy of the strip being transferred from the furnace, and an inner liner of an alloy that can be readily welded to a roll. The inner liner material is fused to the rim material to form a composite ring.

Abstract: A steel mill roll has its ends supported in self-aligning bearings that do not require a liquid or grease lubricant, and which are capable or operating at roll shaft temperatures up to 1500.degree. F.

Abstract: A method for centrifugally casting a multi-alloy low adhesion furnace roll, includes separately casting each layer and then solidifying the layers when all layers have been cast.

Abstract: A furnace roll for transferring steel strips from an annealing furnace has several spaced rings along the body of the roll. The rings have a width and diameter chosen such that the load on each ring is optimized depending upon the material of the strip and the ring material. The selected ring material is relatively insoluble with the strip material.

Abstract: A bubble-actuated pump is used for removing dross from the surface of a bath of molten metal. A modification of the pump is employed for delivering molten metal to the dross for diluting it.

Abstract: A bubble-operated pump for recirculating molten metal in a bath of such metal.

Abstract: A fabricated bubble operated pump for diluting dross in a steel treating bath.
