| Abstract |
Thermal deformation of slab mold during continuous casting was analysed by the coupled finite element method with heat and thermo-elasto-plastic deformation. In order to consider the effect of air gap on the heat transfer coefficient between strand and mold, thermal deformation of strand and temperature distributions in strand and mold were calculated. The effects of mold thickness, temperature of cooling water, velocity of cooling water and mold taper on deformation of mold was investigated. The deformation of mold was due to the difference of thermal expansion between mold and supporting plate of mold. During heating in continuous casting process, mold was deformed toward the strand, while mold was deformed toward the supporting plate of mold during cooling. The amount of deformation increased with increasing the hot face temperature in mold. |
