Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
The double-deck industrial furnace lining of one of the present utility model, as shown in Figure 1, comprises internal layer, skin is coaxially connected with outside internal layer, internal layer is rearranged vertically by several inner ring 1, and skin is rearranged vertically by several outer shrouds 2, and inner ring 1 and outer shroud 2 are annular or arch; Form arc shaped slits a7 between adjacent two inner ring 1, form arc shaped slits b8 between adjacent two outer shrouds 2, arc shaped slits a7 and arc shaped slits b8 mutual dislocation vertically.
As shown in Figure 2 and Figure 3, inner ring 1 is made up of several internal layer blocks 1-1, and form radial gap a9 between adjacent two internal layer block 1-1, outer shroud 2 is made up of several outer block 2-1, forms radial gap b10 between adjacent two outer block 2-1; Radial gap a9 and radial gap b10 along the circumferential direction mutual dislocation.
