Abstract
The invention relates to an immersion device and a method for detecting a position of an optical cored wire using an immersion device. An immersion device for measuring a temperature of a metal melt inside an electric arc furnace vessel with an optical cored wire comprises a blowing lance for blowing purge gas into an entry point to the vessel and a detecting means for detecting a position of the optical cored wire. The optical cored wire can be moved in a feeding channel and/or in the blowing lance relative to the entry point. The detecting means is configured to detect the presence of the optical cored wire in or close to the blowing lance. This enables short distances between the leading end of the fiber and the melt and, thus, short time intervals between temperature measurement sequences.
