Abstract

Bu buluş, ateşe dayanıklı seramik kaplama ihtiva eden ve içerisinden metal eriyiğe bir sıvının gönderilmesine yarayan püskürtme tertibatının (20) geçtiği metalürjik eritme potası ile ilgilidir. Bu tertibat şu bileşenlerden oluşmaktadır: a) boru şeklinde ateşe dayanıklı seramik kılıf (26), b) bu kılıfa (26) eş merkezli olarak yerleştirilmiş bir dış boru (34), c) bu dış borunun (34) içerisinde eşmerkezli olarak konumlanmış bir iç boru (38), ve d) bu iç ve dış boru (38, 34) arasında eksensel yönde bulunan bir kanal (36) ki bu kanal e) eksensel yönde ileri ve geri hareket ettirilebilecek, ayrıca f) ateşe dayanıklı seramik kaplama içerisinde döndürülebilecek şekilde yerleştirilmiştir. Tertibat ayrıca ikincil metalürjik işleme yöntemiyle de ilgilidir.The present invention relates to a metallurgical melting crucible containing a refractory ceramic coating through which the spray device (20) for sending a liquid to the metal melt passes. This assembly consists of the following components: a) a tubular fire-resistant ceramic sheath (26), b) an outer tube (34) placed concentrically to this sheath (26), c) an inner tube (34) located concentrically inside this outer tube (34). pipe (38), and d) a channel (36) in the axial direction between these inner and outer pipes (38, 34), which channel e) can be moved back and forth in the axial direction, and f) rotated within the refractory ceramic coating. has been placed. The apparatus also relates to the secondary metallurgical processing method.
