【Abstract】 A new type of crucible for aluminum melting was developed, which could be used as the substitute for imported crucible. By adopting proper chemical composition and foundry method the required structure and properties were obtained. The working life of new type crucible was 2-3 times and more of the imported crucible.更多还原
