The invention discloses a laying method for a lining of a reduction furnace. Laying of the lining is performed in the reduction furnace from bottom to top. The laying method for the lining comprises the following steps: a: the lower half part of the lining is laid in a staggered-joint manner, expansion joints are reserved in a spray gun area, after half of the lining is laid, an arch form is manufactured, and a support is prepared; and b: the upper half part of the lining is also laid in a staggered-joint manner, a filler is well filled, when laying reaches a lock brick, the lock brick needs to be processed in advance, after the lock brick is completely laid, a steel plate of 2-3 mm in thickness is adopted for strengthening and locking, flat laying is adopted at the broken part of a spherical arch and expansion joints are reserved. By adoption of the laying method, the service life of the lining of the reduction furnace is prolonged, the operation efficiency is improved, the maintenance cost of the reduction furnace is lowered, and high economic benefits are brought for enterprises.
