Title:
CONTINUOUS TEMPERATURE MEASURING APPARATUS AND COMPONENT ANALYZING APPARATUS FOR MOLTEN METAL
Document Type and Number:
Japanese Patent JPH05312651
Kind Code:
A
Abstract:
PURPOSE:To obtain an apparatus for continuously measuring temperature and analyzing components of molten metal stably. CONSTITUTION:The continuous temperature measuring/component analyzing apparatus for molten metal comprises an optical measuring unit 4, a tuyere 3, and a gas transmissive porous body 15 having central through hole, wherein the optical measuring unit is disposed at the base end part of the tuyere while the gas transmissive porous body 15 is projected in front of the tuyere so that a through hole 17 will communicate with the central port of the tuyere. Since a desired mashroom shape is obtained for the measuring hole tuyere and a straightforward optical path is obtained stably, temperature and compositional elements of molten metal can be measured stably, continuously, and accurately.
