JAPAN'S IRON AND STEEL INDUSTRY

Measures against water pollution in the iron and steel industry.

During the last ten years or so, a number of statutory provisions have been enacted with the eventual object of controlling and restricting the amount of pollution which can be permitted or tolerated in the water systems of the European Continent. Against this background the authors examine the iron and steel industry as it exists in France, tabulating the principal processes likely to be encou...

Characterization and Catalytic Behaviour of Nanostructured Iron Oxide Powder from Waste Pickle Liquor of Steel Industry

Nanostructured iron oxide powder that has been recovered from waste pickling liquor unit of steel industry was studied for oxidation catalytic applications. In this research, the powder was characterized by X-ray diffraction (XRD) and transition electron microscopy (TEM) for determination of phase structure, morphology and particle size. Furthermore, the specific surface area of the powder was ...

Kinetics of Ceramic Phase Crystallization in a Glass Derived from Wastes of Iron and Steel Industry

Intensified environmental regulations have posed numerous challenges in the disposal of industrial wastes. The steel industry is one of the biggest production industries, with a considerable amount of daily wastes. Production of glass-ceramic from the steel industry waters is one of the proper solutions for this problem. In this study, the application utilization of different wastes (such as bl...
