What Makes Refractories So Special?
Refractory Products are highly heat resistant materials used as linings for furnaces, kilns, reactors and incinerators. Exposure to high temperatures leads to negative effects such as corrosion and wearing out. Refractories are resistant to the stress and physical deformation induced by extreme heat temperatures. These comprise of a broad class of Refractory Products classified on the basis of their nature, their fusion temperatures, physical shape. Different industries use Refractories on the basis of their applications.
There are two basic categories of Refractories defined by their shape- Brick Refractories and Monolithic Refractories. Monolithic Refractories are of varying shapes. Some of them are of complex shapes while others vary on the basis of weight and length. The common types of Refractories are fire-clay bricks, ceramic fibers, castables, and insulating bricks. Most Refractories are made of non-metallic natural and synthetic materials or a combination of materials namely Alumina, bauxite, silicon carbide, chromite, fireclays, etc.
Characteristics Of Refractories * Different Refractory Materials have different melting points. Depending on the specific refractory elements, the melting points may vary from 3100° to 6300° F. * Porosity is another characteristic that defines Refractories. There are high porosity and low porosity refractory materials. High porosity materials are generally used for thermal back up while low porosity ones are utilize in hotter areas. * Another important characteristic is the size and shape of the refractory material. These characteristics are important as they directly affect the stability of the structure. What Makes Refractories So Special? * The ability of Refractories to withstand high temperatures and trap heat. * Refractories serve as heat conserving components. * They can withstand corrosive acids and materials. * They are resistant to physical deformation and chemical change during high temperatures. * Refractories act as a safeguard for the furnaces, kilns, etc. & saves them from wearing out and other physical damages. * In some service conditions, they can also bear loads. * They are resistant to contamination by the material or product which comes in contact with them. * They maintain thermal stability even during high temperatures and constant thermal cycling.
