Tundish Technology for Clean Steel Production


Book Description

Continuous casting of steel has become a widely used process and an important step in steel production. The worldwide share of continuously cast steel has increased significantly in the last 25 years or so. However, concurrent with this increase in production levels are stringent quality requirements that have become crucial in the face of progressively increasing machine throughputs and larger product dimensions. As a result, steel cleanliness and strict composition control are now the primary concern of steelmakers.The tundish is the last metallurgical vessel through which molten metal flows before solidifying in the continuous casting mold. During the transfer of metal through the tundish, molten steel interacts with refractories, slag, and the atmosphere. Thus, the proper design and operation of a tundish are important for delivering steel of strict composition and quality. This pioneering book is the first of its kind to cover all aspects of tundish technology, ranging from fundamental aspects and theory necessary for understanding the basic concepts of tundish operations to operational aspects of the tundish. Written by internationally recognized experts in continuous casting technology in general and tundish technology in particular, this book is sufficiently fundamental to serve as a graduate-level textbook on process metallurgy or as an important reference for metallurgical researchers; at the same time, it is comprehensive enough to contribute to the understanding of scientists and engineers engaged in research and development in the steel industry.




Tundish Technology for Clean Steel Production


Book Description

The diversity and specialization in orchid floral morphology have fascinated botanists and collectors for centuries. In the past 10 years, the orchid industry has been growing substantially worldwide. This interesting book focuses on the recent advances in orchid biotechnology research since the last 10 years in Taiwan. To advance the orchid industry, enhancement of basic research as well as advanced biotechnology will provide a good platform to improve the flower quality and breeding of new varieties. The important topics covered include the new knowledge of basic genome, through floral morphogenesis, floral ontology, embryogenesis, micropropogation, to functional genomics such as EST, virus-induced gene silencing, and genetic transformation.

Steel Production


Book Description

The authors address the problems of determining the implications of different environmental standards and public policies by investigating their effect on industrial costs and resource use within linear-programming framework. Originally published in 1976




Electroslag Remelting Towards Clean Steel


Book Description

This book introduces the results that the authors have achieved on the study of functional principle of electroslag remelting for production of high-quality clean steel. The dependence of oxygen, sulfur, and non-metallic inclusions on the processing parameters of electroslag remelting is assessed. The fundamentals and technologies of clean steel production by electroslag remelting have been applied in the round to discuss oxygen, sulfur, and non-metallic inclusions evolution and control. A general concluding remark and a perspective for future work are present. The book is likely to be of interest to university teachers, researchers, R&D engineers, and graduate students in material processing and pyrometallurgy who wish to explore innovative technologies that lead to more energy-efficient and environmentally sustainable clean steel production.




Separation Technologies for the Industries of the Future


Book Description

Separation processes—or processes that use physical, chemical, or electrical forces to isolate or concentrate selected constituents of a mixture—are essential to the chemical, petroleum refining, and materials processing industries. In this volume, an expert panel reviews the separation process needs of seven industries and identifies technologies that hold promise for meeting these needs, as well as key technologies that could enable separations. In addition, the book recommends criteria for the selection of separations research projects for the Department of Energy's Office of Industrial Technology.
