abstract
The invention relates to a heat storage brick and a preparation method thereof. Iron ore particles with iron oxide content not less than 60% are selected as main raw materials, and yellow mud and sodium silicate solution are used as auxiliary materials, which are sintered at high temperature, wherein the weight percentage of each component is: 87-93% of iron ore particles, 3-6% of 0-3mm yellow mud and 4-7% of sodium silicate solution; The preparation method is as follows: firstly, the main raw materials of granular iron ore are washed with water, then dried or dried to make the water content within 0.5%, then yellow mud and sodium silicate solution are mixed and molded in proportion, and the molded mixture is sintered at the high temperature of 930- 1030℃. The heat capacity is large, it can store more heat, and the thermal conductivity is low, which makes it have the characteristics of slow heat release and long heat release time. It is used to store heat in the inner core of heater, and the energy saving effect is obvious. At the same time, it has the characteristics of simple manufacturing process, low production cost, good product quality, wide application range and easy popularization and application.
