- 摘要： [Problem] The present invention addresses the problem of providing a high heat conductive heat insulation material that can reduce the hindrance to temperature rise of a refractory during preheating, shorten the preheating time, and improve heat insulation properties after preheating.
  [Solution] A heat conductive heat insulation material 1 according to the present invention coats the surface of a refractory used for casting and contains a substance imparting heat conductivity. Therefore, the high heat conductive heat insulation material can reduce the hindrance to temperature rise of the refractory during preheating, shorten the preheating time, and improve the heat insulation properties by forming voids as the high heat conductive heat insulation material burns out.

- 摘要： A continuous casting nozzle 1 includes a nozzle main body 2 and a nozzle hole 3 formed to extend through the nozzle main body so that molten steel flows therethrough, and an alumina-hardly-adherable refractory 5 containing components of MgO, CaO and SiO 2 is disposed on an inner surface defining the nozzle hole. Consequently, even when a temperature of the nozzle is low, adhesion of inclusions in molten steel to a portion in contact with the molten steel can be reduced, with the result that the nozzle hole can be prevented from being blocked and the continuous casting nozzle can contribute to an improvement in the steel quality.
