| Abstract: | The casting method of a heavy section nodular iron wheel was introduced：semi-pressured and bottom-gated gating system was adopted,some chills were put at the hot spots,and stream inoculation was conducted during pouring process.Inspection showed that the wheel had no casting defects,no nodularization fading,and all mechanical properties met requirements. |
