In order to verify the accuracy of a one-dimensional computer program of finite difference heat transfer model for heat flow analysis in continuous casting process, computed surface temperature and solidified shell thickness were compared with measured values. The computed results showed a good agreement with measured values. This implies that the computer program is effective means for predicting temperature profile and solidified shell thickness of slab. The computed solidification constant(k) with S3 cooling pattern(Specific water flow : 0.57㎏-water/㎏-steel) was 23.8㎜/min^(0.5) and k with FK cooling pattern(Specific water flow : 0.94㎏-water/㎏-steel) was 26.3㎜/min^(0.5) in No.2 Continuous Slab Caster of POSCO. Relationship between heat transfer coefficient(h : J/㎡ see·℃) and water flux on the surface of hot slab was obtained as following equation by the laboratory scale experiment. h=14.02 W^(0.7◎)
