Iron-based heat storage brick and preparation method thereof
The invention provides an iron-based heat storage brick and a preparation method thereof. The iron-based heat storage brick comprises the following raw materials in percentage by mass: 30-40% of hematite powder, 15-25% of magnesite powder, 20-30% of titanium concentrate powder and 20-30% of argil. According to the preparation method, all the raw materials are mixed with a binding agent solution, compression molding and sintering are performed, and the iron-based heat storage brick with high heat storage density, high compression strength and good high-temperature stability is obtained. The preparation method is low in raw material cost, iron oxide in the iron-based heat storage brick can be recycled, and the iron-based heat storage brick is high in economical efficiency, environmentally friendly and wide in application prospect.
本发明提供一种铁系蓄热砖及其制备方法，所述铁系蓄热砖的组成原料按质量分数计包括：赤铁矿粉30～40％、菱镁矿粉15～25％、钛精矿粉20～30％和陶土20～30％；所述制备方法将各原料与结合剂溶液混合后，进行压制成型并烧结，得到了储热密度高、耐压强度大且高温稳定性好的铁系蓄热砖。所述制备方法的原料成本低，铁系蓄热砖中的氧化铁可回收再利用，经济性高且绿色环保，具有广阔的应用前景。
