METHOD FOR MEASURING TEMPERATURE OF MOLTEN BODY IN COPPER CONVERTER

摘要

PURPOSE:To eliminate trouble due to fume generated in a converter, etc. by covering the outer end of the tuyere of a copper converter with a transparent body, regulating the flow rate of gas blown into a molten body in the converter to Mach 1 or above in the standard state at the tip of the tuyere, and measuring the temp. of the molten body with a noncontact type thermometer through the transparent body. CONSTITUTION:A transparent body 12 is fixed in a cap 7 on a tuyere box 1 of a copper converter to form a peeping window. A radiant pyrometer 13 is placed at a position close to the transparent body 12 at the outside of the converter and on the extension of a tuyere pipe 3. Air is sent to the tuyere from a blast pipe 2 so that the flow rate (Nm/sec) of the air blown into the molten body 8 under high pressure is regulated to Mach 1 or above in the standard state at the tip of the tuyere pipe 3, and the temp. of the molten body 8 is measured with the pyrometer 13 through the transparent body 12.
