The temper rolling is applied to eliminate the stretcher strain, to improve the flatness and to control the surface roughness of rolled-sheet as the finishing process in cold rolling. However, there are some problems remain in analysis of the temper rolling. The classical rolling theory based on the rigid plastic theory, can not deal with non-uniform elastic-plastic deformation in the thickness direction, because the deformation is partly concentrated on the surface layer of the sheet. This paper presents an elastic-plastic finite element analysis of stress and strain behaviors in plane strain temper rolling for as-annealed mild steel sheet. In the analysis, the upper yield stress, the lower yield stress and yield point elongation are taken into account for the stress-strain relation of material rolled. For the contact boundary between roll and deforming material, both slipping and sticking are considered, and the Coulomb friction law is employed to represent the slipping friction. Furthermore, calculated rolling force by the EP-FEM is compared with that by the classical rolling theory as Karman's equation and that obtained by a laboratory scale rolling experiment with bright rolls or dull rolls. As the results, in the case of small friction between roll and deforming material, the rolling force obtained by Karman's equation coincide with that by EP-FEM and that by experiment.

Effect of B addition (B≦0.012%) on the cold rolling and recrystallization textures of Fe-36%Ni alloy has been studied. The {001} <110> preferred orientation, which is increased with increasing B contents, developes in the surface layer. The surface rolling texture penetrates from the surface to a depth of less than about 20μm. The pure-metal type rolling texture of {4 4 11} <11 11 8> which is found in the inner layer, irrespectively of B contents. The surface recrystallization texture of B containing alloys is almost random. The inner recrystallization texture showes a gradual change with increasing B contents from the {100} <001> orientation to the {4 4 11} <11 11 8> orientation of rolling texture which is retained after completion of recrystallization.

Manufacturing factors and properties of hot rolled 60 kgf/mm^2 class dual phase (DP) steels by two producing methods, which were suitable for mass production, were discussed. (1) As rolled extra low temperature coiling method developed using three step cooling pattern, called as "Inline controlled quenching (ICQ) method" was suitable for massproduction of DP steel with low alloying component (1.5%Mn and low Si content less than 0.15%). It was important for stabilization of mechanical properties to control the temperature and period of the second air cooling stage between water cooling stages according to variation of chemical composition. (2) The continuous annealing (CA) method as the heat-treated type process was fit for the case that low yield ratio was especially required. (3) As the result of investigation about formability, bake hardenability and weldability, it was proved that the hole expansion ratio of DP steel was remarkably improved with inclusion shape control by calcium-addition, bake hardenability of ICQ-DP steel was larger than the CA steel due to higher solute nitrogen content, and that weldability was excellent except flash-butt welding for auto wheel rim. (4) DP steels were successfully appliable to auto wheel disc and most parts made of hot rolled mild steels and their applications have been useful for weight reduction.

In 1977, Japan Institute of Art Japanese Sword was reconstructed Tatara furnace for direct steelmaking from iron sand and charcoal, so called Kera-oshi method. This Tatara furnace called Nittouho Tatara was constructed on the base of Yasukuni Tatara furnace which had been operated until the end of the World War II in Yokota city in Shimane prefecture. For this reconstruction of the furnace and the direct steelmaking operation, the great effort of Mr. Yoshizo Abe as a leader Murage had been paid and his techniques should be made clear. Until the age of Yasukuni Tatara, Kera-oshi method was consisted of 4 stages ; Komori, Komoritsugi, Nobori and Kudari. In the 2nd stage of Komoritsugi, Komori iron sand had been used to charge because of easy reduction and production of pig iron. In 1977, Mr. Abe had met difficulty to collect Komori iron sand. Then, he developed the new technique of Tatara operation using only Masa iron sand for the last two stages in spite of Komori iron sand. He controlled the wet of iron sand and made the residual time of iron sand longer in furnace. The reduced iron particles have enough time to absorb carbon for producing pig iron.
