| Abstract: | The foundry method design of a nodular iron reductor housing with ferrite matrix was de-scribed. The problems which maybe arise in castings production were analyzed. No defects such as shrinkage cavity/porosity, cold shut, misrun and cracking and so on have been found with castings produced with designed method, and the blow hole and sand inclusion defects have been also con-trolled effectively. Material properties met technical requirements. The rationality of the method has been confirmed. |
