FURNACE WALL STRUCTURE OF MOLTEN METAL CONTAINER AND METHOD FOR CONSTRUCTING FURNACE WALL OF MOLTEN METAL CONTAINER

摘要

This furnace wall structure of a molten metal container contains a heat insulation material which exhibits a thermal conductivity of 0.01 to 0.15 W/(m·K) in a temperature range of 25 to 300°C and which has a melting point of 1000 to 1400°C and a thickness of 2 to 10mm in a position in the longitudinal section view, said position being within a thicknesswise region of 0.75×T to 0.92×T (mm) from the inside surface of a magnesia/carbon refractory toward a steel shell. T is the thickness of the furnace wall exclusive of the steel shell.
