Maintenance and Application of High Alumina Refractory Castables High alumina refractory castable are widely applied in high heat industries. Specifically they are used in building power plant blast furnace melting furnace heating furnace soaking furnace heat treatment furnace and induction furnace in different parts. the castable (W/Cc) evaluated. The setting time was measured by the Vicat needle the specific area was evaluated by Blaine and the refractoriness evaluated by Orton cone. The castable had also its compres-sive strength measured at 24 hours after a drying process at 110°C for 36 hours and after a heat treatment at 815°C and 1400°C for 4 hours.

Alumina Castable-High Alumina Refractory-Rongsheng Kiln
High standard quality alumina castable can be used in smelting furnace heating furnace and other thermal facilities with no slag or corrosion. Alumina refractory castable made from high purity alumina cement has very low calcium content. As we all know calcium is a common component in the raw material of alumina refractories. Oct 04 2012 · In this study four types of castables as calcium-aluminate cement (CAC)-bonded and nano-silica (NS)-bonded castables based on tabular-alumina and bauxite aggregates were prepared to investigate the replacement of the calcium-aluminate cement by NS. All samples were allowed to dry at 110 °C then fired at 800 and 1200 °C. Bulk density and apparent porosity of samples were measured.
