Characteristics

CLC series

By the reduction of the mixing amount of alumina cemet, CLC shows following characteristics.

  • Spalling resistance at high temperature is strengthened.
  • Alkali resistant against foreign alkaline component is strengthened.

Alkali resistace test

(1) Corrosive agent:NaCl 1000℃×24Hrs

Conventional castable
Matrix became weekend
CLC-A6CL49-RE
No deterioration occurred in strength.

QD Series

QD series, developed by our own technology, have following properties compared with our conventional RE type (RE type: adding additives for preventing explosive spalling)

  • Reduction of the possibility of explosive spalling
  • hort dry out time becomes possible with high speed heating up
