Heating Furnace Competitive Price Good Abrasion Resistance Fire Clay Brick for Cement Kiln
Refractory fire clay bricks can be used as high-temperature
building materials and structural materials for building kilns and
various thermal equipment, and can withstand various physical and
chemical changes and mechanical effects at high temperatures.
Feature:
Thermal shock resistance: Strong resistance to sudden changes in
temperature without damage.
Compressive strength: withstands maximum pressure capability.
Flexural strength: Strong ability to withstand shear pressure.
Thermal conductivity: Under the condition of unit temperature
gradient, the heat flow rate per unit area of the material is
related to the porosity.
