It was carried out the melting and refining of iron scrap by the inductive heating of coke packed bed under reducing atomosphere. Folloing results were obtained as a summary.(1)Experiments and mathematical modeling were performed with inductive heating of a single cylindrical graphite. (2) Two layr packed bed for iron sphere and coke was heated inductivelly. Results obtained were numerically simulated by a mathematical model. (3) New measuring method of liquid hold-up was developed on the basis of the measurements of electric resistivity in the electrolytical liquid. (4) New method was proposed for examining flow pattern of continuous or discontinuous liiquid flow in packed bed. (5) Measuring method of wetted area on the solid surface was proposed. (6) Wall effect of packed bed could be removed by the lining of hemisphere sheet. (7) Smelting phenomena ofiron scrap was investigated by using the mathematical model of high-frequency induction furnace. Results obtained were reported as several papers. Some new measuring methods such as liquid hold-up, flow pattern and wetted area will be widely applied to another fields because it is novel methods.

它是通过在还原原子球下的可乐床的电感加热来进行铁废料的融化和精炼。 （1）实验和数学建模是通过单个圆柱石墨的电感加热进行的。 （2）将两个用于铁球和可乐的床床加热。通过数学模型在数值上模拟了获得的结果。 （3）根据电解液中电阻率的测量，开发了新的液体持有方法。 （4）提出了新的方法来检查包装床中连续或不连续的液体流动的流动模式。 （5）提出了固体表面上湿面积的测量方法。 （6）填充床的壁效应可以通过半球床单的衬里去除。 （7）使用高频感应炉的数学模型研究了铁废料的冶炼现象。获得的结果报告为几篇论文。一些新的测量方法，例如液体持有，流动模式和湿区域将被广泛应用于其他领域，因为它是新方法。
