Title:
ガラス溶融物を誘導するための貴金属管、その使用及びそのための方法
Document Type and Number:
Japanese Patent JP4197909
Kind Code:
B2
Abstract:
The double-walled noble metal duct ( 1 ) for conducting a glass melt has an outer noble metal pipe ( 1 b) and an inner noble metal pipe ( 1 a) extending within the outer pipe, so that an inner space ( 21 ) is formed within the inner pipe and an intermediate space ( 23 ) is formed between the inner pipe ( 1 a) and the outer pipe ( 1 b). The intermediate space is completely filled with glass melt when the double-walled noble metal duct conducts the glass melt, when the outer pipe ( 1 b) has an exhaust vent ( 4 ). The outer pipe ( 1 b) also has a bottom outlet ( 7 ) communicating with the intermediate space for removal of oxygen bubbles formed on the outer wall. The noble metal duct can be used in glass conditioning and in the manufacture of glass articles that are devoid of polyvalent ions.
