KA40
Dezhen
690220
Characteristics of this series products are as follow:
The brick is made from sintered special grade clay, pressed by high pressure and sintered at high temperature, with excellent spalling resistance, alkali,sodium,sulfur,chlorine and alkalic salt corrosion. Low thermal conductivity, a better and ideal choice for steel industry.
