[0002] At present, in the production process of lithium battery electrode materials, a roasting furnace is required to carry out a roasting treatment on them, and a rotary kiln is usually used for the roasting preparation of lithium battery electrode materials.

[0003] However, the lining of the lithium battery sintering furnace in the prior art is mostly built by combining refractory bricks and high-temperature mortar in the furnace. Since the sintering temperature of the mortar for mortar joints is lower than the firing temperature of the refractory bricks, the high-temperature mortar will shrink or expand under the influence of the high temperature in the furnace, causing instability in the furnace structure and cracks in the brick joints of the refractory bricks. It is impossible to effectively prevent the high-temperature heat inside the kiln from escaping, resulting in heat loss inside the kiln and unstable temperature inside the kiln, which not only causes high fuel consumption, but also easily leads to the situation that the lithium battery electrode material after baking does not meet the production requirements. For this reason, we propose a lithium battery sintering kiln lining. Utility Model Content

Through the cooperation of the positioning block 203 and the locking groove 204, multiple lining bricks 103 are formed into a whole. When the lithium battery electrode material is fired at high temperature in the furnace, the expansion of the locking frame 201 made of metal will further increase the stability of the installation of the lining brick 103, prevent the formation of large gaps between the lining bricks 103 and the lining bricks 103 during the firing process in the furnace, and prevent the heat in the furnace from dissipating.
