Refractory castable for predecomposition system of cement kiln for co-processing solid waste
The invention relates to a refractory castable for a predecomposition system of a cement kiln for co-processing solid waste. The refractory castable is prepared from the following components in parts by weight: 59 to 64 parts of refractory aggregate, 36 to 41 parts of refractory powder, 9 to 12 parts of binding agent, 0.2 to 0.6 part of composite functional agent and 1.35 to 2.12 parts of additive. The refractory aggregate is waste silicon carbide kiln furniture aggregate, the refractory powder is waste mullite-corundum kiln furniture powder, and the composite functional agent is boron carbide fine powder. The invention aims to solve the problems that the production cost of the refractory castable which is used as the cone part of the decomposing furnace and the cyclone preheater of the cement kiln for co-processing solid waste and the lining of the blanking articulated chute at present is higher, and the refractory castable is easy to be corroded and crust due to a severe and harsh use environment during co-processing solid waste.
一种协同处置固废水泥窑的预分解系统用耐火浇注料，按照重量比，由59‑64份的耐火骨料、36‑41份的耐火粉料、9‑12份的结合剂、0.2‑0.6份的复合功能剂和1.35‑2.12份的添加剂制成，其特征在于，耐火骨料为废碳化硅质窑具骨料，耐火粉料为废莫来石‑刚玉质窑具粉，复合功能剂为碳化硼细粉。本发明旨在解决目前用作协同处置固废水泥窑分解炉及旋风预热器的锥部和下料溜管内衬的耐火浇注料生产成本较高，以及在协同处置固废时因为恶劣严苛的使用环境导致易蚀损、易结皮等问题。
