Abstract:
A method for producing a turbine casing for a rotating machine is provided. The casing is manufactured by a casting process, and is cast in two casing halves which are separated by a parting plane which passes axially through the turbine casing. Each casing half is first cast in one piece in each case, and each casing half is separated into at least two casing sections which are joined together for forming a casing half in each case.
