Refractories Market: Overview
Refractories or headstrong materials will be materials produced using thermally stable mineral totals, added substances, and a cover stage. They are nonmetallic, inorganic, heterogeneous, and permeable materials that can withstand high temperatures, for example, 500°C, 1500°C or significantly more, without experiencing physicochemical changes while as yet staying in contact with metals, gases, and liquid slag. ASTM International characterizes refractories as ‘non-metallic materials having concoction and physical properties that make them relevant for structures or as parts of frameworks that are presented to conditions above 538°C.’
Refractories Market: Drivers & Restraints
Refractories are primarily and extensively used in industrial processes, wherein they perform four basic functions. They act as a thermal barrier between a hot medium such as liquid metal, liquid slag, molten salt, or flue gas and walls of the structure containing the medium. They provide strong physical protection and prevent erosion of walls by keeping the hot medium circulated. They offer protection from chemical corrosion. They also act as thermal insulation and ensure heat retention.
Refractory materials are expensive and if they fail to perform their functions properly, considerable loss of production time can occur. Selection of proper refractories is important, as it influences product quality and energy consumption. Accordingly, the best suited refractory is the one that provides the best balance between installation and maintenance cost.
Refractories Market: Key Segments
The global refractories market can be segmented based on type, material, alkalinity, end-user industry, and region. In terms of type, the market can be segregated into specialty refractories and monolithic refractories. Specialty refractories are shaped refractory materials. Bricks are the most common specialty refractories. Refractories can be manufactured in interlocking shapes and wedges; molded or pressed to be used in walls and floors; or even curved to fit inside ladles and boilers. Monolithic refractories are unshaped refractory materials. These refractories do not have any definite form and they are given shape only during their application.
The refractories market can be segmented based on material. A wide range of materials are employed to produce refractories. These include silica, fireclay, magnesia, alumina, dolomite, silicon, zirconia, and carbon. Usually, refractories are tailor-made as per the application. The material is selected depending on several factors such as operating atmosphere, temperature profile, mode of operation, and expected characteristics.
Alkalinity of refractories is decided on the basis of their reaction with slags. Based on alkalinity, the market can be segmented into basic refractories, acidic refractories, neutral refractories, and special refractories. Basic refractories are non-reactive to alkaline slags and used with them. Similarly, acidic refractories are non-reactive to acidic slags and used with them. On the other hand, neutral refractories remain chemically non-reactive to both acidic and alkaline slags, and are used with both.
Refractories Market: Regional Outlook
In terms of end-user industry, the refractories market can be segmented into iron & steel, cement, glass, nonferrous metals, and others. Refractories are used most commonly in the iron & steel industry. In terms of region, the global refractories market can be segmented into North America, Latin America, Europe, Asia Pacific, and Middle East & Africa. China is a major consumer of refractories in the world and is expected to maintain its position during the forecast period.
