Microstructure, chemical composition, physical property and high temperature process of furnace materials from Shuiquangou site were analyzed in order to promote an exploratory scientific study on cast iron smelting furnace materials in ancient China. The results showed that raw materials were locally collected and gone through a screened process; there were at least two productions of furnace lining which used in different parts of the furnace. Furnace materials can provide enough Na2O, Al2O3, and SiO2 into slags. The refractoriness of them were about 1 200–1 300°C, and the smelting temperature was among 1 300– 1 500°C.
