Special high-strength wear-resistant castable for cement kiln flashboard
The invention belongs to the technical field of refractory castables, and particularly relates to a special high-strength wear-resistant castable for a cement kiln flashboard. According to the preparation method, mullite granules, mullite powder, magnesium aluminate spinel powder, silicon carbide powder, aluminum titanate powder, silicon oxide ultrafine powder, silicon nitride ultrafine powder, pure calcium aluminate cement, explosion-proof fibers, a water reducing agent and a binding agent are mixed, so the purpose of effectively preparing the special castable for the cement kiln flashboard is achieved. The castable special for the cement kiln flashboard is high in strength and good in wear resistance, the flashboard is not prone to falling off in the frequent adjustment process, the composite explosion-proof fibers can be melted to form air holes to reduce internal stress, the internal stress can be evenly distributed through the connection effect of the carbon fibers, and finally, the castable is not liable to burst.
本发明属于耐火浇注料技术领域，尤其涉及一种水泥窑闸板专用的高强度耐磨浇注料。本发明通过将莫来石粒料、莫来石粉料、镁铝尖晶石粉料、碳化硅粉料、钛酸铝粉料、氧化硅超细粉料、氮化硅超细粉料、纯铝酸钙水泥、防爆纤维、减水剂以及结合剂混合的方式，达到有效制得水泥窑闸板专用浇注料的目的。本发明具有水泥窑闸板专用浇注料强度高，耐磨性能好，闸板处频繁调节过程中不易脱落，以及复合型防爆纤维不仅可以熔化形成气孔来减轻内部应力，还可以通过碳纤维的连接作用将内部应力分摊均匀，最终可以保证浇注料不易爆裂的优点。
