APPARATUS FOR TEMPERATURE MEASUREMENT IN A CONVERTER

摘要

The apparatus is used for exact temperature determination of the steel melt of a converter with the aid of the measurement of the thermal radiation. There is a radiation measuring instrument connected at one end of a passage. The other end of the passage immerges into the steel melt. The immerged end of the passage has a cross-sectional area of less than 1 cm2 and an inert gas flows there in the steel melt at the rate of 10 grams per minute for each 1 mm2 of the cross-sectional area of the immerged end.
