REFRACTORY LINING STRUCTURE OF ROTARY KILN

摘要

PROBLEM TO BE SOLVED: To prevent the corrosion of a kiln rotary outer cylinder and to reduce the occurrence of they mechanical damage of a refracting material, by a method wherein an iron plate is interposed between the inner surface of a kiln rotary outer cylinder and a lining refracting material. ;SOLUTION: An iron plate 3 is interposed between a kiln rotary cylinder (an outer cylinder) 1 and a lining fire resisting material 2. Lining with a monolithic refractory as the refractory material 2 is effected, a long one in a rotary direction is interposed as the iron plate 3, but a shaped baked or not-baked refractory may also be used. Further, the iron plates having a given size are interposed at the backs of respective shaped refractory. This structure prevents a kiln rotary cylinder from corrosion due to a material containing alkali, chlorine, or sulfur, a mixture thereof, and variation in oxidation and reduction, and widely suppresses so that the mechanical damage of a lined refractory material is prevented from acceleration owing to the increase of deformation and bending of a kiln.;COPYRIGHT: (C)1999,JPO
