High Thermal Shock Resistance Fe2O3 Clay Refractories Bricks
Description: High temperature solid clay bricks are classified to Medium-duty Fireclay brick,High-duty Fireclay brick and Super-duty Fireclay brick. sintered brick is made from clinker clay through mixing, shaping, drying, sintering and matching It has good corrosion resistance and wear resistance, good thermal shock resistance and good writing resistance. High mechanical strength, high temperature volume stability.
Low coefficient of linear expansion
Low thermal conductivity,
Strong resistance to the acid slag erosion,
Excellent thermal shock resistance,
High Refractoriness under load,
Low high-temperature creep rate.
