熱伝導率迅速測定装置

Thermal Conductivity Rapid Measuring Apparatus

平橋 明(Akira Hirahashi) 川村 紘一(Koichi Kawamura) 宮本 一真(Kazuma Miyamoto) 要旨 : 耐火物や断熱材の熱伝導率を正確に知ることは重要である。本文では川崎製鉄㈱計量器工 場にて開発した“熱線法”にもとづく熱伝導率測定装置の原理，仕様，特徴および２，３の測 定例を述べている。本装置を用いて，10kcal/m･h･℃以下の耐火物や断熱材の熱伝導率を， 常温から1000℃まで迅速に，連続的に測定することができる。 Synopsis :

It is significant to accurately determine the thermal conductivity of refractories and adiabatics. This article describes the principle, specifications, characteristics of the thermal conductivity measuring apparatus with Hot Wire Method developed by Kawasaki Steel Corporation, together with some data obtained using this apparatus. This apparatus has made it possible to get rapid and continuous measurements of the thermal conductivity under 10 kcal/m･h･℃ ranging from room temperature to 1000℃. (c)JFE Steel Corporation, 2003
