The grate cooler’s function is to cool clinker from 1300°C to approximately 100°C, imposing stringent requirements on refractory materials due to drastic temperature changes. Under these process conditions, refractory materials in the grate cooler throat must withstand erosion and corrosion from high-temperature dust-laden flue gas. Refractory materials in the grate cooler low wall must endure abrasion from high-temperature clinker, severe temperature fluctuations, mechanical impacts, and corrosion from alkaline gases.

 

Tongda provides comprehensive refractory design and construction solutions for grate coolers. Key areas such as the grate cooler throat and low wall can utilize precast components, eliminating the need for formwork and curing, reducing cracking and spalling during kiln heating, and minimizing high-temperature wear. At the same time, in-factory prefabrication ensures more stable product performance, thereby extending the service life of the product.
