The refractory lining of the decarbonizer is exposed to considerable thermal effects (the design of some decarbonizers implies installation of additional burners), as well as the action of chemically aggressive substances (alkali, sulfates, chlorides). Andalusite-based high-aluminous refractories with silicon carbide admixtures (SiC) are well-suitable for operation under these conditions. These concretes have a low adhesion degree of dust fused on the clinker; they are resistant to the action of alkalis and abrasive wear, and have high thermal resistance values. We suggest producing the heat insulation layer from lightweight concretes or a calcium silicate slab.
Our Engineering Department will help you select an individual lining diagram pursuant to the customer’s requirements, prepare the lining design, and calculate the amount of the required materials.
