A metal product manufacturing device is provided to remove, with higher accuracy, impurities from a molten metal of a non-ferrous metal or another metal containing the impurities, obtain the molten metal having higher purity, and obtain a high-purity non-metal product or another metal product from the high-purity molten metal.

A casting equipment monitoring system detects that the condition of casting equipment is deteriorating before the casting equipment fails, or detects that the quality of castings produced by the casting equipment is deteriorating before it becomes clear that the castings are defective products. The casting equipment monitoring system includes: an information collecting device that collects, in real time, data measured by equipment within the casting equipment; and a diagnostic device that compares, in real time, the collected data with a control value, and displays a diagnosis result if the diagnostic device determines that the collected data has deviated from the control value.

A pour cup assembly (10) includes a pour cup (12) of frusto-conical shape and which has an inlet end (14), of relatively larger diameter, and an outlet (16), of relatively smaller diameter. The assembly (10) also includes two yokes (18, 20) each including a body section (22) with a part frusto-conical internal profile and opposing arms (24, 26) extending laterally from the body section (22) and that lie in a common plan. Each arm (24, 26) has a bore or hole (30) therein. The body portion (22) has an external profile that is also part frusto-conical in shape and has one or more circumferential grooves (32) in its outer surface. The grooves (32) extend parallel to the arms (18, 20) and transverse to the longitudinal direction of the body portion (22). The grooves (32) in use accommodate a tie element disposed around the body portion (22) and cup (14) to hold the assembly together while the assembly (10) is subsequently coated with ceramic material to form the pour cup assembly. This is typically done at the same time as creating the investment cast around the invested pattern. The arrangement provides a pour cup assembly (10) that can be packaged and transported more efficiently and that can be handled with lifting assistance. The assembly also allows for the use of different sizes of pour cups with the same yokes, making the assembly more versatile.

A transfer pump has a pump base with a pump chamber and an output port in the top surface of the pump base. A riser tube extends from the outlet and terminates at a launder having a first end juxtaposed the riser tube, an open top, and a bottom having a launder opening. This structure enables the movement of molten metal out of a vessel with relatively little turbulence.

A melting apparatus for steel production includes a support structure to support a shell for the production and tapping of steel, and a source or zone for the emission of fumes resulting from the tapping of the steel from the shell. The melting apparatus also includes a tapping hood integrated into the support structure and provided with a suction mouth positioned directly above the zone for the emission of fumes, the shell is provided with a bottom wall in which an E.B.T. is provided for tapping the steel.

A metallurgical system for producing metals and metal alloys includes a fluid cooled mixing cold hearth having a melting cavity configured to hold a raw material for melting into a molten metal, and a mechanical drive configured to mount and move the mixing cold hearth for mixing the raw material. The system also includes a heat source configured to heat the raw material in the melting cavity, and a heat removal system configured to provide adjustable insulation for the molten metal. The mixing cold hearth can be configured as a removal element of an assembly of interchangeable mixing cold hearths, with each mixing cold hearth of the assembly configured for melting a specific category of raw materials. A process includes the steps of providing the mixing cold hearth, feeding the raw material into the melting cavity, heating the raw material, and moving the mixing cold hearth during the heating step.
