Alkali-Resistant Bricks for Cement Kilns
Alkali-resistant bricks for cement kilns refer to clay refractory bricks that are primarily made from low-alumina refractory clay and possess alkali erosion resistance in cement kiln systems. The main raw materials for alkali-resistant bricks include mullite, pyrophyllite, and silica. The alkali resistance mechanism of these bricks involves reacting with alkali metal oxides at high temperatures to generate a high-viscosity liquid phase, which forms a glaze protective layer. This layer covers the brick surface and blocks surface pores, preventing the penetration…
