Abstract

The invention relates to a refractory lining combination brick of a shaft kiln, which is mounted in a door closing position of a refractory lining of the shaft kiln, wherein four areas are arranged inthe door closing position. The combination brick comprises a first support brick, a second support brick, and a door closing lock brick positioned between the first support brick and the second support brick, wherein the first support brick and the second support brick are oppositely arranged to form cone hopper space; and the door closing lock brick is positioned in the cone hopper space. The overall structure of the lining is more stable; and the service life of the lining is prolonged.

Description

technical field [0001] The invention relates to the technical field of refractory inner linings of thermal furnaces, in particular to a composite brick for refractory inner linings of shaft kilns. Background technique [0002] The kiln refractory lining is the working surface of the thermal furnace for high-temperature calcination production, and is the main structure for the double-chamber lime shaft kiln to withstand high temperatures. Usually, the bottom structure of the double-chamber lime shaft kiln channel is composed of a steel structure and a refractory lining wrapped with the steel structure. The refractory lining, on the one hand, protects the bottom steel structure from oxidation by the high-temperature air flow in the furnace and isolates materials, and on the other hand, relies on the combination with the steel structure to play the role of supporting the upper lining masonry. [0003] Generally, the refractory lining mainly adopts unshaped refractory pouring st...
