  Refractory, in simple terms, is a type of material that can retain its strength in high-heat conditions and is resistant to chemicals. The process of producing high-performance refractory requires synthetic & natural materials, which are usually non-metallic. These materials can withstand high temperatures, physical wear & corrosion caused by chemical agents or other forms of mechanical stress. For instance, industries such as steel require high-performing refractory coatings because the furnaces go through extreme temperatures during the process of converting iron into steel. Likewise, refractory materials are also essential for industries that produce copper, glass, cement, and aluminium, among others. 

  

  Important Factors to Consider While Selecting Refractories

  Evaluation Criteria

  The four factors of evaluation while designing insulation systems and selecting the right insulation materials are: Physical properties, thermal performance, chemical properties and costs.

  Type of Refractory

  To achieve satisfactory results from the type of refractory material you choose for a certain furnace, you need to have a better understanding of the limitations and the strong points of different types of refractories. Most often, you can achieve desirable results by using different types of refractories in different parts of the same furnace. 

  Operating Conditions

  The selection of refractory materials should always be based on the properties and specifications that are suitable for the operating conditions. There may be cases where the refractory materials fail even though the operating practices haven't been changed. For this reason, the skill of masonry work and proper equipment for application are very important. 

  Quality of Refractory

  The success and failure of thermal equipment is totally dependent on the refractories. This also dictates the safe and profitable operation of the plant. Reviewing manufacturing facilities, quality-control programs, and testing the important properties is essential.

  One must carefully analyse the service conditions, availability of refractory materials, ease of installation, along with future repairs and maintenance, which are some of the most important factors to consider during the selection and design of refractories.
