Influence of Production Factors on Lightweight Refractory Thermal Conductivity
Tóm tắt
Information is provided about the thermal conductivity of highly porous refractory specimens prepared using kaolin, clay, combustible, sintering additives, and also foam. Data for the properties of samples of lightweight refractories prepared by different methods are analyzed. The emphasis is on combination of specimen heat insulation and strength properties The thermal conductivity achieved for foam samples is 0.37 W/(m·K) at 650°C in combination with satisfactory compressive strength of 3.8 MPa.
