What is a common application of refractories in industrial processes?

Refractories are specifically designed to withstand high temperatures and harsh conditions, making them ideal for use as linings in high-temperature furnaces. In industrial processes such as metal smelting, glass manufacturing, and ceramics production, furnaces operate at extremely high temperatures. The primary function of refractories in this context is to provide insulation and to protect the furnace structure from heat and chemical attack, ensuring operational efficiency and safety.

The unique composition of refractory materials allows them to maintain their structural integrity and resist melting or deformation when exposed to elevated temperatures. This characteristic is crucial, as any failure in the furnace lining can lead to catastrophic failures in processes that require precise temperature control. Hence, implementing refractories as linings is vital in industries that demand durability and resistance to thermal shock, abrasion, and chemical reactions.
