In petrochemical plants and refineries, special refractory products are used more frequently than standard classical refractory materials. In addition to low alumina high silicon dioxide refractories with acidic character very special corundum based products with 90-99% alumina content is needed. These refractories have high performance. Hence, the refractory consumption speed in these sectors is slow and the consumption rate is very low. With its qualified products, Haznedar Group promptly responds to the needs of such sectors with a requirement of wide range of refractory materials.
