A nozzle put into a molten metal in vertical upwards continuous casting for casting a cast product by pulling up the molten metal, the nozzle includes a nozzle body having an intake hole through which the molten metal is taken in and which is formed in a lateral surface of the nozzle body and a flange portion formed on lower side of the intake hole and projecting beyond the nozzle body.

An example molten material funnel includes a first outlet lip and a second outlet lip. The first and second outlet lips are configured to both contact molten material communicated through the molten material funnel.

Systems and methods are disclosed for using magnetic fields (e.g., changing magnetic fields) to control metal flow conditions during casting (e.g., casting of an ingot, billet, or slab). The magnetic fields can be introduced using rotating permanent magnets or electromagnets. The magnetic fields can be used to induce movement of the molten metal in a desired direction, such as in a rotating pattern around the surface of the molten sump. The magnetic fields can be used to induce metal flow conditions in the molten sump to increase homogeneity in the molten sump and resultant ingot.

It is intended to suppress flaming and smoking due to combustion of combustible substances in a certain-shaped joint material, while maintaining hot sealability of the certain-shaped joint material. A certain-shaped joint material for hot installation is obtained by: adding organic additives to a blend in a combined amount of 26 mass % to 50 mass %, with respect to and in addition to 100 mass % of the blend, wherein the blend comprises 50 mass % to 90 mass % of gibbsite type aluminum hydroxide raw material, 1 mass % to 9 mass % of clay, and 9 mass % to 23 mass % of graphite, with the remainder mainly composed of an additional refractory raw material; and subjecting the resulting mixture to kneading, forming and drying.

A casting nozzle comprises an elongated body defined by an outer wall and comprising a bore defined by a bore wall and extending along a longitudinal axis, X1, from a bore inlet to a downstream bore end, said bore comprising two opposite side ports, each extending transversally to said longitudinal axis, X1, from an opening at the bore wall defining a port inlet adjacent to the downstream bore end, to an opening at the outer wall defining a port outlet which fluidly connects the bore with an outer atmosphere. Upstream from, and directly above each port inlet, one or two flow deflectors protrude out of the bore wall and extend from an upstream deflector end remote from the port inlet to a downstream deflector end close to the port inlet.
