Refractories

Definition

Refractories are heat-resistant nonmetallic ceramic materials used in high-temperature industrial processes.

Purpose

The purpose of refractories is to withstand high temperatures and harsh environments in industrial processes, protecting equipment and maintaining structural integrity.

Examples of Use

• Refractories are used to line furnaces, kilns, and reactors in the steel, glass, and cement industries.
• In foundries, refractories are used in molds and crucibles to withstand molten metal temperatures.
• Power plants use refractories to line boilers and incinerators, ensuring they can operate at high temperatures without degradation.

Related Terms

• Firebrick: A type of refractory brick designed to withstand high temperatures.
• Kiln: A high-temperature oven used for firing ceramics or processing materials.
• Insulating Brick: A type of refractory material with low thermal conductivity, used to reduce heat loss.

Notes

Refractories are critical for the efficiency and safety of high-temperature industrial processes, requiring precise composition and installation to perform effectively.
