Abstract:In the current study,the standard and production status of rack steel for offshore platform at home and abroad were described from the view of manufacturing of extra-thick plate blanks,and the production technology and difficulties of the extra-thick plate blanks were analyzed. Based on this,the water-cooled mould casting technology with sequential solidification and the result of pilot test were introduced,and the feasibility of casting plate blanks of rack steel with water-cooled mould casting technology was predicted by simulation. The simulation results show that the rack steel plate blanks of large piece weight and high quality can be generated by water-cooled mould casting technology with sequential solidification,which explores a economical and practical process for producing rack steel plate blanks.
