Abstract: A continuous coating line includes a snout assembly exposed to molten metal. The snout assembly includes a snout tip positioned about a steel strip that is immersible in the molten metal to provide a seal around the steel strip during entry into the molten metal. The snout tip includes a refractory material that is resistant to wear, abrasion, and corrosion when the snout tip is exposed to the molten metal.

Abstract: A system for forming a steel material includes a first binder, a second binder, a punch and a carrier blank. The first binder and the second binder are configured to form a draw bead shape in the steel material by compressing the steel material between a draw bead protrusion and a draw bead channel. The punch is configured to form the steel material relative to the first binder and the second binder. The carrier blank is positioned on a surface of the steel material and is configured to cover a portion of the draw bead shape during formation of the draw bead shape in the steel material.

Abstract: A weld wheel cleaning system is provided to clean or remove a layer of embedded material and other debris produced from welding from the working surface of a weld wheel. Such a weld wheel cleaning system includes a cleaner with an abrasive material positioned on an outer surface of the cleaner. The cleaner is positionable adjacent to the weld wheel such that the abrasive material is aligned with the working surface of the weld wheel. An actuator can be used to selectively actuate the cleaner with a force sufficient to remove the layer of embedded material from the working surface of the weld wheel with the abrasive material. The debris from the cleaner can be removed by a vacuum.

Abstract: An apparatus for pumping molten metal includes a transport conduit and a gas conduit. The transport conduit includes an inlet portion and an exit portion. The inlet portion defines an inlet port. The exit portion defines an exit diameter and an exit port. The inlet port is in communication with the exit portion to communicate molten metal from the inlet port to the exit port. The gas conduit defines a gas delivery conduit. The gas delivery conduit is in communication with the exit portion and defines a gas delivery diameter. A ratio of the gas delivery diameter to the exit diameter is 0.5 or more.
