What is Furnace Lining (with picture)
Paul Scott. Furnace lining is needed to protect furnace parts from extreme heat. Furnace lining is a protective and insulating layer of heat resistant material attached to the inside of the shell hearth and tap holes of a furnace. This layer serves to protect the furnace parts from the extreme heat developed during smelting operations.
