Abstract

With considering the boundary conditions for secondary cooling thermal transmission

a mathematical model for thermal transmission to suit slab caster has been established. The measurement results by using infrared thermoscope to measure the surface temperature of 230 mm x 1650 mm slab of X65 pipeline steel conform to simulation results. The cast solidification of pipeline steel with different casting speed has been simulated and calculated by mathematical model to analyze the effect of casting speed on thickness of slab shell in mold

surface temperature of slab and length of liquid core

it is obtained that at given secondary cooling conditions

in order to obtain reasonable surface temperature of slab the casting speed of pipeline steel slab should be 0.9-1.2 m/min.
