Formula and preparation method of steel slag heat storage brick for high-temperature heat storage
The invention belongs to the technical field of heat storage materials, and particularly relates to a formula and a preparation method of a steel slag heat storage brick for high-temperature heat storage. The steel slag heat storage brick comprises the following components in percentage by mass: 64-65% of steel slag, 5-6% of talc, 9-10% of feldspar, 5-6% of kaolin and 15-16% of bauxite. The method comprises the steps of mixing, ball-milling, drying, adding a binder, granulating, aging, pressing and sintering to obtain the steel slag heat storage brick. The steel slag heat storage brick prepared by the invention is high in heat-conducting property, can realize relatively fast heat absorption and heat release during application, can realize high-temperature heat storage to 1300 DEG C, is relatively high in heat stability at a high temperature, is free of obvious cracking, is excellent in mechanical property, and can realize low-cost high-temperature heat storage.
本发明属于储热材料技术领域，具体涉及一种用于高温储热的钢渣蓄热砖配方及其制备方法。所述钢渣蓄热砖包括：钢渣、滑石、长石、高岭土和铝矾土，其中钢渣、滑石、长石、高岭土、铝矾土的质量百分比为64％‑65％：5％‑6％：9％‑10％：5％‑6％：15％‑16％。经过混合球磨、干燥、添加粘结剂、造粒、陈腐、压制及烧结得到钢渣蓄热砖。本发明制备的钢渣蓄热砖导热性能好，应用时可实现较快的吸热和放热，可以实现高温蓄热到1300℃，同时高温下热稳定性较好，无明显开裂，力学性能优良，可以实现低成本高温储热。
