Product Information
High Alumina Fire Bricks are a type of refractory material that is widely used in various industrial applications due to their excellent thermal and mechanical properties. Among these bricks, the SK36 and SK38 grades are specially designed to withstand high temperatures and chemical attacks, making them suitable for use in furnaces, kilns, and other high-temperature processing units.
While they share many similarities, there are some differences in their properties due to variations in their alumina content and manufacturing processes.
