The invention relates to a lime shaft kiln refractory lining combined brick. The lime shaft kiln refractory lining combined brick is used for being arranged at the non-door-closing position on a shaftkiln refractory lining. The combined brick comprises a first combined brick body and a second combined brick body which is adjacent to the first combined brick body, the combination face of the firstcombined brick body and the second combined brick body is a vertical face, and the vertical face penetrates the furnace center of a shaft kiln. By means of the lime shaft kiln refractory lining combined brick, the whole structure of the lining is very stable, and the service life of the refractory lining is effectively prolonged.
