The data obtained by experiments of small scale are readily explained by the reduction mechanism which was previously reported(1)(2). The diffusion constant of CO gas through sponge iron layer at 1000°C(Dvs) is 0.62 cm2/sec. Carburization, sulfur elimination and tin removal are also discussed. The conditions used for plant layout are calculated by the method which was obtained in the previous reports(1)(2).
