• Unshaped Refractory Materials

          Unshaped refractory materials are defined as” mixtures consisting of aggregates, additives, and binders, prepared for direct use in the state of delivery or after adding suited liquids”. In contrast to refractory bricks, they are without specific shape and are in majority placed in larger sections behind molds and templates forming a monolithic lining. Gunning installations without the requirement for a mold are increasing due to ease of application and higher installation speed.

Tabular alumina fraction

abular alumina is made of Al2O3, after ingredients, grinding and forming, smelting in high temperature furnace turned to α- Al2O3.

Tabular alumina has good heat resistance and good bulk temperature thermal shock capabilities. The crystal staggered plate shape, to increasing the mechanical strength of the particles
