Example Embodiment
[0043] Example 1
[0044] In this embodiment, fused and high-purity composite raw materials are used to manufacture low thermal conductivity magnesia-aluminum spinel bricks for cement kiln transition zone. The formula of each layer material is:
[0045] Refractory layer: sintered magnesia with a particle size of 5-0mm accounting for 45% of the total, and magnesia-aluminum spinel with a particle size of 4-0mm accounting for 10% of the total. The particle size of fused magnesia is 3-0mm, which accounts for 40% of the total. The grain size of corundum is 2-0mm, accounting for 5% of the total.
[0046] The specific configuration is as follows:
[0047] 5-0mm sintered magnesia 45%
[0048] 4-0mm Magnesium Aluminum Spinel 10%
[0049] 3-0mm fused magnesia 40%
[0050] 2-0mm corundum 5%
[0051] The above-mentioned raw materials are weighed, mixed, and kneaded with a naphthalene-based binder to make a low thermal conductivity magnesia-aluminum spinel brick refractory layer raw material.

[0075] Example 3:
[0076] In this embodiment, fused and high-purity composite raw materials are used to manufacture low thermal conductivity magnesia-aluminum spinel bricks for cement kiln transition zone. The formula of each layer material is:
[0077] Refractory layer: sintered magnesia with a particle size of 5-0mm accounting for 68% of the total, and magnesia-aluminum spinel with a particle size of 4-0mm accounting for 10% of the total. The particle size of fused magnesia is 3-0mm, accounting for 19% of the total. The particle size of corundum is 2-0mm, accounting for 3% of the total.
[0078] The specific configuration is as follows:
[0079] 5-0mm sintered magnesia 68%
[0080] 4-0mm Magnesium Aluminum Spinel 10%
[0081] 3-0mm fused magnesia 19%
[0082] 2-0mm corundum 3%
[0083] The above-mentioned raw materials are weighed, mixed, and kneaded with a naphthalene-based binder to make a low thermal conductivity magnesia-aluminum spinel brick refractory layer raw material.
