Abstract：Thin-web beam blank embodied the near net-shape characteristic. Temperature distribution of thin-web beam blank continuous casting was calculated by finite element numerical simulation. The effect of casting speed and secondary cooling water ratio on temperature, solidified shell thickness and liquid core length was analyzed. The results are concluded as follows: when the web width is thinner, the thermal conductivity is lower, the shell thickness of web and fillet center is about 4mm thinner than flange tip’s; when casting speed made every increase of 0.1m/s, the surface temperature at the mold exit will increase 80-100℃ and the solidified shell thickness will be thinned 0.8-1.2mm and liquid core length will be reduce by 1.2-1.6m; when water ratio in secondary cooling made every increase of 0.05L/kg, the surface temperature at secondary cooling exit will reduce by 8-16℃ and liquid core length will reduce by 0.13m.
