Abstract：The small molten iron ladles used in domestic foundries are usually lined with single-layer refractory material. In order to slow down the temperature drop of molten iron during the pouring process, a new small type of lining structure of molten iron ladle was designed. The lining was made of three refractory materials with thermal conductivity. The results show that the three-layer refractory lining design slows down the temperature drop of molten iron in the pouring process,and has significant effect on the improvement of casting temperature and energy saving and emission reduction. Under the same working condition, the final casting temperature of molten iron in the three-layer lining is 29 ℃ higher than that in the single-layer lining.
