Research on Hot Extrusion Technology of C-shape Steel
AP1000 nuclear power station is the advanced third generation nuclear technology in the world,and C-shape steel is used as structural trestle of its cooling water tower.Through the process innovation of die design,deformation,heating,glass lubrication and other aspects,TP304L billet with diameter of 277mm was successfully extruded into C-shape steel with horizontal extrusion machine.Product dimensions and mechanical properties of C-shape steel meet the design requirements after examination,and it's applied to the AP1000 nuclear power station in China.
