Castables for CDQ Coke Oven

CDQ castable is a high-strength, wear-resistant refractory material mainly used in coke drums in CDQ devices. It aims to extend the service life of the coke drum lining, reduce heat loss, and lower operating and maintenance costs.
It is mainly composed of high-alumina bauxite, hollow alumina balls, alumina powder, silicon powder and other ingredients. It has high refractory temperature, compressive strength and bulk density, and has good thermal conductivity and thermal stability. This material has been improved on the basis of traditional castables. By adjusting the particle grading and adding different admixtures, the amount of cement is reduced, the medium-temperature strength and load softening temperature are improved, and the thermal conductivity is reduced, thereby improving the overall performance and service life of the material.
This castable has the following characteristics and application advantages:
High temperature resistance: It can withstand high temperature environment and maintain stable working performance.
Anti-stripping: It has good anti-stripping performance, ensuring that the material will not fall off easily during long-term use.
Erosion resistance: It can effectively resist the scouring and erosion of coke and protect the lining of the coke tank.
Anti-scouring: It has strong ability to resist medium scouring and reduce material loss. Good thermal shock resistance: It has good thermal shock stability and can adapt to environments with drastic temperature changes.
