Refractory Components for Walls, Roof, Hearth

The linings of industrial furnaces require stable materials that retain their strength at high temperatures, have resistance to abrasion and to furnace gases, and have poor thermal conductivity (good heat-insulating capability). [Pg.398]

Modem firebrick (from fireclay, kaolin) and silica brick are available in many compositions and many, many shapes for a wide range of apphcations and to meet varying temperature and usage requirements. High-density, double-burned, and super-duty (low-silica) firebrick have high-temperature heat resistance, but relatively high heat loss thus, they are usually backed by a lower density insulating brick. [Pg.398]

Insulating firebrick (kaolin) with many very small air pockets is a modem replacement for tufa. [Pg.398]
