摘要:
A furnace plant including at least one furnace vessel comprising side walls, a bottom and a roof. At least one heater is configured to heat metal in the furnace vessel. A compartment includes sidewalls lined with refractory material. The compartment forms an extension of the furnace vessel. At least one electromagnetic stirrer is arranged outside and adjacent to the compartment. A refractory plate is arranged inside the compartment. The refractory plate includes an upper edge configured to be positioned below a meniscus of molten metal and includes a lower edge positioned spaced apart from a bottom of the compartment. The plate is arranged such that a gap between the plate and a wall of the compartment increases toward the bottom of the compartment.
