Rotary kiln according to their uses: mainly used for calcining cement clinker kilns, production of dry and wet cement kiln cement kiln production of two categories. Metallurgy chemical kiln is mainly used in metallurgy industry, steel plants depleted iron ore magnetic roasting; chromium, nickel, iron ore roasting; refractories plant bauxite mine and alumina calcined aluminum roasting clinker, aluminum hydroxide; chrome ore roasting plants and chrome ore and other minerals. Limekiln (ie, active lime) for firing steel mills, ferroalloy plant with lime and light burned dolomite. In the process of calcining kiln will be some with corrosive gases or materials. After investigation, the most serious corrosion in the rotary kiln where the middle section, in front of no significant corrosion, indicating that corrosion has a culture. Appears after etching the cylinder structure having a multilayer sheet corrosion. Volatiles produced by the body in a kiln at 1200 degrees Celsius ingredients to the volatile composition and cement and bricks react refractory erosion. Clay with adsorption capacity can reach every brick eroded material through the cylinder. Solve corrosion kiln measures to be taken include: improved kiln system operability, improve the quality and masonry kiln lining methods to increase his shielding effect. Lower raw material composition adjustment harmful elements in the composition of sulfur alkali match, reducing the chance of accumulation of harmful substances.
