建立了连铸板坯直接热装加热数学模型，并用有限差分法进行求解，获得了各期加热温度分布及加热时间，此模型可用于连铸板坯直接热装加热制度的确定。
The mathematical model of direct hot charging of continuous casting slab was established and solved by finite difference method. The distribution of heating temperature and heating time were obtained. The model can be used to determine the direct hot charging heating of continuous casting slab.
