Preparation and use method of mullite combined SiC-based cement kiln grate cooler hanging brick
The invention discloses a preparation and use method of a mullite combined SiC-based cement kiln grate cooler hanging brick, which is prepared from silicon carbide with the particle size of 5-3mm, silicon carbide with the particle size of 3-1mm, silicon carbide with the particle size of 1-0.5 mm, silicon carbide with the particle size of 0.5-0.088 mm, silicon carbide with the particle size of 0.088 mm, metal silicon with the particle size of 0.088 mm, mullite, mullite with the particle size of 0.5-0.088 mm, mullite with the particle size of 0.088 mm and polyvinyl alcohol as binding agents. According to the preparation and use method of the mullite combined SiC-based cement kiln grate cooler hanging brick, silicon carbide is adopted as a main material, and a certain amount of aluminum-rich mullite is added to react with silicon dioxide formed by oxidation of silicon carbide at high temperature to form new mullite, so that the refractoriness under load of the material is increased, and the utilization rate of the material is increased; polyvinyl alcohol is used as a binding agent to improve the strength of a semi-finished product, and the prepared hanging brick has good wear resistance and structural stability, the service life is remarkably prolonged, the requirement for long-term operation of a cement kiln can be met, the frequency of furnace shutdown overhaul is reduced, and economic benefits are remarkable.
本发明公开了一种莫来石结合SiC基水泥窑篦冷机吊挂砖的制备和使用方法，由粒径5～3mm碳化硅、粒径3～1mm碳化硅、粒径1～0.5mm碳化硅、粒径0.5～0.088mm碳化硅、粒径0.088mm碳化硅、粒径0.088mm金属硅、莫来石，由粒径0.5～0.088mm莫来石、粒径0.088mm莫来石、聚乙烯醇作结合剂，本发明一种莫来石结合SiC基水泥窑篦冷机吊挂砖的制备和使用方法，采用碳化硅为主要材料，添加一定量的富铝莫来石在高温下与碳化硅氧化形成的二氧化硅反应形成新的莫来石，从而提高材料荷重软化温度，聚乙烯醇作结合剂提高半成品强度，而且本发明所制备的吊挂砖具有良好的耐磨性和结构稳定性，使用寿命显著提高，可满足水泥窑长期运行的需求，减少停炉检修的频率，经济效益显著。
