GENCO SPECIAL REFRACTORIES FOR CARBON BLACK REACTOR

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
