Zirconium mullite composite silicon carbide castable for garbage incinerator and prefabricated part
The invention provides a zirconium mullite composite silicon carbide castable for a garbage incinerator. The zirconium mullite composite silicon carbide castable comprises a coarse aggregate, a medium aggregate, a fine aggregate, an additive, a binding agent and explosion-proof fibers, the coarse aggregate comprises zirconium mullite particles with the particle size of 3-5 mm, the medium aggregate comprises silicon carbide particles with the particle size of 1-2 mm, the fine aggregate comprises zirconium mullite powder with the particle size of 0.1-0.6 mm, and the additive comprises alumina powder, silicon oxide powder and silica powder. The pouring material further comprises a certain amount of additives, the additives comprise aluminum oxide, silicon oxide and silica powder, firstly, the silica powder can fill tiny gaps of the material and reduce the porosity due to the fact that the particle size is small, and secondly, aluminum oxide and silicon oxide react at high temperature to form a mullite structure; when a mullite structure is formed, volume expansion occurs, and pores formed by the explosion-proof fibers can be blocked, so that the apparent porosity is reduced.
本发明提供了一种垃圾焚烧炉用锆莫来石复合碳化硅质浇注料，包括粗骨料、中骨料、细骨料、添加料、结合剂和防爆纤维；所述粗骨料包含粒径为3~5mm的锆莫来石颗粒，所述中骨料包含粒径为1~2mm的碳化硅颗粒，所述细骨料包含粒径为0.1~0.6mm的锆莫来石粉料，所述添加料包含氧化铝粉料、氧化硅粉料和硅微粉。本发明提供的浇筑料中还包括一定量的添加料，添加料包含氧化铝、氧化硅和硅微粉，首先硅微粉由于粒径较小，能够填充材料的微小空隙，降低孔隙率，其次氧化铝和氧化硅在高温下反应能够形成莫来石结构，形成莫来石结构时发生体积膨胀，可以阻塞防爆纤维形成的孔隙，从而降低显孔率。
