Preparation method of flue castable for reducing gas corrosion in fluidized bed boiler
The invention relates to the technical field of flue castable materials, in particular to a preparation method of a flue castable material for reducing gas corrosion in a fluidized bed boiler, and the preparation method comprises the following steps: S1, preparing mixed powder, S2, preparing a splicing layer, S3, preparing a reinforcing material, and S4, preparing an anti-corrosion flue castable material. According to the invention, the splicing layer is adopted, so that the corrosion resistance, especially the gas corrosion resistance, of the flue castable is remarkably improved, and the mechanical strength and the impact resistance of the material are improved; the reinforcing material is poured, the surface layer material is poured after airing, the three materials are combined for use, and the corrosion-resistant flue pouring layer with high comprehensive quality is obtained; the strength and the wear resistance of the pouring layer are further improved by pouring the reinforcing material; and a long-acting protective layer with high temperature resistance, acid medium resistance and chemical smoke corrosion resistance is formed through the surface layer material.
本发明涉及烟道浇注料技术领域，具体是涉及一种降低流化床锅炉中气体腐蚀的烟道浇注料的制备方法，包括：S1、混合粉配料，S2、制备拼接层，S3、制备加固料，S4、制备防腐蚀烟道浇注料；本发明采用拼接层，显著提高烟道浇注料的耐腐蚀性能，尤其是对抗气体腐蚀的能力，提高材料的机械强度和抗冲击性能；浇注加固料、晾干后浇注表层料，三种材料组合使用，得到综合质量强的耐腐蚀的烟道浇注层；通过浇注加固料进一步提升浇注层的强度和耐磨性；通过表层料形成具有耐高温、耐酸性介质和耐化学烟雾腐蚀的长效保护层。
