bocal inferior de panela acionado por indução

摘要

A ladle (2) or other container for molten metal (5) is provided with an outlet nozzle (4) that allows a stream of molten metal to flow by heating the nozzle (4) to the melting temperature of the metal (5). The nozzle (4) is, for example, tubular and made of AI2O3 or SiO2 and is surrounded by a graphite tube (8) in thermal contact with the nozzle (4). The nozzle (4) is heated by heating the surrounding graphite tube (S) inductively. Once the temperature of the nozzle (4) exceeds the liquidus temperature of the metal (5) in the ladle (2), the metal (5) will flow out of the ladle (2) through the nozzle (4).
