  • SPECIAL REFRACTORIES FOR CARBON BLACK REACTORdownload

GENCO SPECIAL REFRACTORIES FOR CARBON BLACK REACTOR

Special refractories used for carbon black reactors require very high refractoriness and excellent resistance to thermal spalling.
GENCO special refractories for carbon black reacors provides,

High refractoriness

  • Used purity over 99.7% fused alumina and purity over 99.5% chrome refractories to minimize impurity, then can get a high temperature melting point.

Abrasion resistance

  • High strength through sintering in excess of 1750℃ under ultra-high temperature

Densification

  • Porosity reduction by densification of gradation and sintering under high temperature.
  • Protect permeation of alkali and SiO2 as ash through low pores

Stability of volume expansion

  • A good stability of volume expansion under high working temperature by using raw materials of high purity
  • Contraction prevention under working temperature by pre-heat treatment
