| Abstract: | The configuration of nodular iron housing used for ASF355 gear box was introduced.In order to reach the high nodularity requirement,some measures were adopted including strict controlling chemical composition,adjusting melting charge mature ratio,stabilizing nodularizing treatment process,intensifying stream inoculation and strengthening operation control etc.As the result,the nodularity fully reached 90% and higher. |
