General Information
CMAX corundum bricks use compact electrosmelted corundum and alumina powder as main raw materials., shaped under high pressure after machine-blending and fired at high temperature.Alumina content in more than 48% of a neutral refractory material. By alumina or other higher raw material forming and calcined alumina content. Thermal stability, high refractoriness in more than 1770 º C. Good slag resistance, used for building steel-making furnace, glass furnace, cement rotary kiln lining.
Feature
Low porosity
High compressive strength
Good chemical stability
Application
Linings of high-temp industrial kilns and furnaces
