Frequently Asked QuestionsWhat is Refractory?It is unfortunate that the superb protection provided by perfectly installed and selected refractory products is not better understood because there is always a product for every situation.Wherever there is metal such as steel or aluminium and high temperatures, refractory products are used to insulate the metal from the heat, thus protecting it and maintaining its integrity. The product or products used depends upon the individual requirements but usually, heat resistant fire bricks, castable cements or rammable plastics are the products of choice because they are consistently reliable and provide long service. Some products are also abrasion resistant which ensures a long life in extreme industrial situations. The right product correctly installed will protect the metal and save a considerable amount of money long term. In boilers, refractory products are used to pack gaps and openings to keep the fire within the fire box and prevent energy from escaping. Even more importantly, refractory products provide seals to ensure correct gas-flow. Refractory linings such as castable cements are also used to line wet and dry ash hoppers while kao-wool, ceramic cards and boards are used where heat is less extreme. What are refractory products and their purpose?Whatever the product, its purpose is to insulate, protect and seal for a long period of time. Fire bricks differ from ordinary bricks because they are considerably more than the baked clay bricks used as veneers on exteriors of buildings. Scientifically designed specifically for specialist application, they vary in density, hardness, shape, weight and size. Industrial kiln bricks are shaped to accommodate the circular rotary kilns but considerable skills are required to ensure they perfectly installed.EBR supervises its comprehensive services from design to construction.
