A fundamental model is proposed to flatten the temperature distribution of a high temperature steel slab. It is composed of the impinging jet removing the heat to the edge of the slab and the porous medium converting gas enthalpy into thermal radiation. As the first stage, the characteristics of flow situation and impingement heat transfer caused by a laminar slot jet are numerically obtained for the dimensionless distance between the nozzle exit and the heated surface H=0.5~1.5, the dimensionless distance between the heated side surface and the porous medium C=1.5~5.0 and the Reynolds number R_e=600~1200. Experiments were also carried out by impinging air to a uniformly heated slab. Numerical values are compared with experimental results. The effective conditions are discussed for practical problems.
