The development work of the super-large ductile iron grinding table was presented from following aspects: molding process, pouring system, chill design, riser position, pouring process and trial manufacture of the product. The casting process was improved and the development risk of the casting was decreased by the theoretical arithmetic and MAGMA simulation. And then the super-large ductile iron grinding table was successfully developed.
