HEATER TUBE FOR MOLTEN METAL IMMERSION
PROBLEM TO BE SOLVED: To provide a heater tube for molten metal immersion comprising a silicon nitride-based sintered body in which thermal conductivity and density are higher than those of the conventional products, the silicon nitride-based sintered body having excellent thermal conductivity.SOLUTION: A heater tube for molten metal immersion 1 has a cylindrical heater housing part 4 equipped with a closed end 2 and an open end 3, in which the heater housing part 4 comprises silicon nitride, a compound containing yttrium, and a compound containing magnesium. An outer circumferential surface of the heater housing part 4 has a surface roughness Ra of 0.5-10 μm.SELECTED DRAWING: Figure 1
【課題】従来よりも熱伝導率や密度が高く、かつ熱伝達率が良好な窒化珪素質焼結体からなる金属溶湯浸漬用ヒーターチューブの提供。【解決手段】閉口端２と開口端３とを備えた筒状のヒーター収容部４を有し、ヒーター収容部４は、窒化珪素と、イットリウムを含む化合物と、マグネシウムを含む化合物と、を含み、ヒーター収容部４の外周面の表面粗さＲａが０．５〜１０μｍである金属溶湯浸漬用ヒーターチューブ１。【選択図】図１
