Abstract
A lightweight ceramic refractory covering for water cooled members forming the structural portion of a metallurgical furnace which is thermally insulating and resists wet scale attack, corrosion and vibrational stresses. The covering comprise an inner layer of thermal insulating ceramic refractory fiber blanket, an open weave ceramic cloth about the blanket, an inner layer of veneering mortar, compressed rings or strips of ceramic fiber material, and a hot face layer of veneering coating.
Claims12
A refractory covering for application to a fluid conveying member comprising a thermal insulating ceramic fiber blanket layer disposed about and contacting the member;
- a cloth wrapped about the blanket, said cloth of an open weave type which permits penetration of a veneering mortar therethrough;
- and a layer of said veneering mortar applied to the cloth, said veneering mortar being dimensionally and chemically compatible with said cloth.
