Cement industry consumes around 15% of global refractory production. The average amount of refractories used in cement industry’s manufacturing of each tone of clinker is around 1kg.
In recent years cement industry has become processed with highly challenging conditions due to the usage of wastes as alternative fuel and raw materials. The quality of consumed wastes and the chemical reactions they undergo effect the refractory linings aggressively. The dominant impacts of alkalis, chlorine& sulfur gasses and halogenic components directly identifies the performance of refractories in pre-heater, rotary kiln and cooler. The presence of acid gasses increases the need of alkali and abrasion resistant refractories to keep a great service performance. Refractory performance is one of the most important parameters in cement industry due to its direct impact on the production speed and capacity. This fact has mandated the use of very special raw materials for the refractories industry. Products containing special components such as silicon carbide and zircon have been developed. Furthermore, alternative products that are free of silicon carbide and zircon content have also been developed to be used in more prevalent locations during the cement production process and yield to lower costs for the customer.
