Objective To study the change of properties of crucible melted aluminum alloy with CaO-based refractories. Methods According to the method of comparative experiment, the performance indexes of aluminum alloy melting with two different lining materials were determined. Results According to the test data, it can be seen that the aluminum alloy melted in two crucibles with little change in performance. Conclusion CaO based refractories can meet the needs of aluminum alloy smelting equipment, which has a wide range of applications.
