Definition

Adjective: - Describing a furnace or similar high-temperature vessel whose interior walls are covered with a layer of refractory material. This lining is designed to withstand extremely high temperatures without melting, degrading, or transferring heat excessively.

Usage

This term is a technical adjective used almost exclusively to describe industrial equipment, particularly furnaces, kilns, boilers, or incinerators. It specifies a key construction feature related to heat resistance.

Examples

• The factory installed a new refractory-lined furnace to improve efficiency and safety.
• For melting certain alloys, a refractory-lined chamber is essential to contain the heat.
• Maintenance of the refractory-lined kiln is scheduled for next month.

Advanced Usage

• The term can be used in a broader engineering context to describe any vessel or duct that must handle high-temperature processes, such as a refractory-lined exhaust stack or a refractory-lined reactor.
