Molten salt furnace pouring material and preparation method thereof
The present invention particularly relates to a molten salt furnace pouring material and a preparation method thereof. The technical scheme comprises: adopting low iron, a coal gangue clinker being subjected to an iron reducing treatment and a corundum material as main raw materials, adopting hydrated alumina as a binding agent, and carrying out inspection, crushing, iron removing, material matching, mixing, random inspection and other steps to prepare the low iron and high anti-thermal shock molten salt furnace pouring material. According to the present invention, the pouring material has strong CO erosion resistance, such that the condition that the furnace hearth lining body become abnormal loose can be effectively avoided; the pouring material does not contain cement, has high high-temperature strength and excellent thermal shock resistance, and can bear strong erosion of high temperature flue gas and coal ash and sharp fluctuation of the furnace hearth temperature; and with the iron reducing and the high thermal shock resistance of the molten salt furnace pouring material, the service life of the furnace hearth lining body can be significantly improved, and the long service life and the high reliability of the molten salt furnace lining can be achieved.
