Refractories: Overview, Types, and Applications

A large number of the heavy-duty sectors are seeking high-quality flow control refractory products that are designed and manufactured to meet their specific needs. As the industrial sector is witnessing a never-before bloom these days, the demand for refractory products has gone to a new high. As for refractory manufacturers in India, the unmatched quality and outstanding performance of products are inspiring the global manufacturers to place repeated orders. 

Refractories: an introduction 

A refractory material or refractory is a material that has an unmatched ability to resist decomposition by heat, any type of pressure, or even a chemical attack. What’s more, these products retain their form and strength even under extreme temperatures. Some of the top categories of refractories include the following:

 

• Polycrystalline
• Polyphase
• Inorganic
• Non-metallic
• Porous, and
• Heterogeneous.

Types of refractories based on thermal conductivity

• Normal refractories - fusion temperature range 1580–1780 °C (e.g. Fire clay)
• High refractories - fusion temperature range 1780–2000 °C (e.g. Chromite)
• Super refractories - fusion temperature of > 2000 °C (e.g. Zirconia).

Applications 

Refractory materials produced and supplied by the leading refractory manufacturers in India are used in a comprehensive range of industrial structures. Some of them include the following:

 

• Furnaces
• Boilers
• Incinerators, and
• Chemical reactors.

The primary job of these refractory solutions is to protect different materials from intense heat. These solutions provide a kind of insulation from the extreme heat that various industrial structures are exposed to. When overlooked, heat damages them severely and creates an immediate need for costly repairs. Some of the major industries that require refractory dry-outs include the following:

 

• Foundry
• Glass
• Aluminum
• Cement
• Ceramic
• Refineries
• Chemical plants
• Power plants, and
• Steel mills.
