Geopolymer unshaped refractory material as well as preparation method and application thereof
The invention belongs to the technical field of refractory materials, and relates to a geopolymer unshaped refractory material as well as a preparation method and application thereof. The geopolymer unshaped refractory material comprises a binder, a fine aggregate and a coarse aggregate, the binder is a solid waste-based geopolymer; the fine aggregate is silicon-manganese slag; the coarse aggregate is silicon carbide particles; the mass ratio of the solid waste-based geopolymer to the silicon-manganese slag to the silicon carbide particles is 1: (1-2): (1-4). The main raw material is industrial solid waste, so that the production cost is greatly reduced. When being applied to a ladle, the molten iron ladle has the characteristics of overall compactness, high cohesiveness, stripping resistance and high temperature resistance, and can bear scouring and transferring of actual iron alloy liquid for nearly hundreds of times, so that the ladle repairing period is prolonged to 10 days once from two days once, the working intensity of workers is greatly reduced, and the use safety of materials and equipment is enhanced.
本发明属于耐火材料技术领域，涉及一种地聚物不定形耐火材料及其制备方法和应用。所述地聚物不定形耐火材料包括粘结剂、细骨料和粗骨料；所述粘结剂为固废基地聚物；所述细骨料为硅锰渣；所述粗骨料为碳化硅颗粒；所述的固废基地聚物、硅锰渣和碳化硅颗粒的质量比为1：1‑2：1‑4。本发明的主要原料为工业固废，大大降低了生产成本。本发明应用于铁水包时具有整体致密、粘结性强、抗剥落、耐高温的特性，可承受近百次实际铁合金液体的冲刷转运，使修包周期从两天一次延长到10天一次，大幅减少工人的工作强度，增强了材料和设备使用安全性。
