05-07The macroscopic physical structure of refractory materials is composed of solid aggregates + matrix + internal pores. The four indicators of bulk density, porosity, water absorption and air permeability essentially characterize the size, quantity, connectivity and distribution structure of internal pores of the materia...

05-06Refractory castable is a finished mixed material containing aggregates (similar to "refractory concrete"), while refractory cement is a pure cementitious powder (aluminate cement). The former can be directly mixed with water for monolithic furnace lining casting, whereas the latter is only used as a binder or...

05-03In high-temperature industrial scenarios such as iron and steel smelting, cement sintering and chemical reactions, furnace temperatures soar to 1000-2000℃. Under the severe scouring of high-temperature molten materials and continuous corrosion of corrosive gas, ordinary materials soften and damage easily. As a core typ...
