Abstract Aiming at the problems of H2 long funnel mold during the production of FTSC ultrathin slab continuous casting process in Tangshan Steel, a new type of mold is developed and designed. The new mold adopts the plane section instead of the funnel section of H2 mold bottom, and shorten the length from 2100 mm to 900 mm. By simulating and optimizing the slab stress in molds, a new shapefunnel mold is designed, which have merits of lower slab stress and strain and smoothtransition of curvesurfaces. The new mold is used in plant trial successfully, the results show that the mold eliminates longitudinal crack during starting cast and improves slab qualities. The mold has great applicability to steel grades and slab sections. The new mold is on a par with the mold imported in lifetime character.
