| Abstract: | To meet the requirement of hardness for as-cast locking bar gray iron castings, the craft process, including chemical composition, charge composition, inoculation, pouring temperature and opening time, was analyzed and explored theoretically. By means of strict implementation of melting process operation, high attention to inoculation measures and strengthening process control of each link in production, the hardness of locking bar castings satisfies the technical requirements, and the castings receive the recognition from the lock manufacturing enterprises. |
