ABSTRACT:
An apparatus for determining carbon contents in molten metal comprising an entrance chamber with an entry port in a side wall, a sampling chamber, a ring-shaped disk to be set between both chambers and a temperature sensing means which is protected from the flowing sample metal by a protective thermal insulation member, protruding through the entrance chamber to the sampling chamber. The molten metal flowing from the entry port is cooled by contacting with the protective thermal insulation member. The insulation member will turn to be a riser when the sample metal starts solidifying in the sampling chamber. Thus enabling precise rapid carbon determination and simultaneously offering appropriate specimen for spectrographic analysis.
