摘要： 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 (10) for measuring a temperature of a metal melt (64) inside an electric arc furnace (60) vessel (62) with an optical cored wire (50) comprises a blowing lance (28) for blowing purge gas into an entry point to the vessel (62) and a detecting means for detecting a position of the optical cored wire (50). The optical cored wire (50) can be moved in a feeding channel (20) and/or in the blowing lance (28) relative to the entry point. The detecting means is configured to detect the presence of the optical cored wire (50) in or close to the blowing lance (28). This enables short distances between the leading end of the fiber and the melt and, thus, short time intervals between temperature measurement sequences.

摘要： A drop-in probe includes a measurement head having an immersion end and an opposing second end having an end face. The measurement head is formed of first and second body halves configured to mate together along a parting line. A sample chamber, arranged within the measurement head, is thermally isolated from a cooling mass thereof and includes a metal wall having a thickness of 2.5 mm or less. An inlet tube has an inlet opening to the sample chamber. The inlet opening has a diameter Dinlet and is spaced apart from the end face of the measurement head at a distance of at least Dinlet/2. When the sample chamber is filled with a sample of the molten metal, a ratio of a mass of the metal sample to a mass of the metal wall of the sample chamber is greater than 2.6 and less than 6.

摘要： The invention refers to a feeding device for feeding an optical fiber from a coil and for recoiling unused fiber for use in an apparatus for measuring the temperature of a melt. The device comprises a support for a coil, a feeding mechanism for decoiling the optical fiber from the coil and recoiling the optical fiber and at least one motor for driving the feeding mechanism. It is the object of the present invention to avoid blockage when decoiling and recoiling a fiber from a coil of a feeding device for feeding an optical fiber. The object of the invention is solved by a device for feeding an optical fiber from a coil and for recoiling unused fiber. The device comprises a support for a coil, a feeding mechanism for decoiling an optical fiber from the coil and recoiling the optical fiber and at least one motor for driving the feeding mechanism. The device comprises a load for the optical fiber which avoids a spring back effect of the optical fiber from the coil. As a result, a blockage is avoided when decoiling and recoiling the fiber.
