Development of Large Thickness Alloy Steel Castings for Fossil Based Power Plant Equipments Using Casting Simulation

New age thermal power plants are employing steam turbines which are functioning at supercritical parameters. Steel castings of various size and weight form important and essential part of these machines. HP/IP Inner Casings, HP Outer Casing, Valve Casings, Valve Covers, etc. are some such castings. Some of these castings have wall thickness as high as 350 to 600 mm and strict control on manufacturing process is required in order to achieve desired quality and mechanical properties in the castings...
