Key Steel Manufacturing Technologies by Collaborative Innovation – serie

The book is an authoritative introductory work on electroslag remelting technology for high-quality special steels. It comprises 9 chapters that cover the electroslag remelting technology and propose two innovative process theories. The first is the cleanliness control theory with invariable process parameters, and the second is the homogenization solidification theory of shallow molten pool at ultrafast cooling and optimal melting speeds, both of which were developed by the authors.Based on these two theories, the book introduces relevant fundamental theories for the regulation of composition homogenization, cleanliness, solidification microstructure, and quality control technology for typical steel grades. In particular, it provides detailed information on electroslag remelting equipment and technologies for totally enclosed protective atmosphere, extra-thicksteel slabs, extra-large ingots, solid and hollow ingots.

This book mainly introduces pioneering technologies in the field of efficient utilization of iron ore, specifically including suspension magnetization roastingtechnology and equipment of complex refractory iron ore, coal-based reduction technology of extremely refractory iron ore, green preparation of super iron concentrate and clean steel base material, energy-saving grinding technology and equipment of new ceramic ball stirring mill, stepped flotation of carbonate-containing hematite and other common key technologies in mineral processing. This book comprehensively elaborates and refines the above-mentioned technologies and equipments from the basic theory, laboratory research, to the semi-industrial test and industrial test level.This book can be read for reference by college teachers and students, researchers, engineering technicians and enterprise administrators in the fields of basic research and applied technology research on the iron ore resource processing.

In this book, the formation causes and the control principles of the surface crack defects of micro-alloyed steel slab, such as the transverse corner cracks, longitudinal depressions in the wide-face off-corners, and the hot charging cracks were discussed. On this basis, the key technologies for the slab surface defects control were proposed. The contents of the book included the control technology for the transverse corner crack of conventional and wide and thick slabs of micro-alloyed steel, the control technology for thin slab corner crack of micro-alloyed steel, the control technology for wide-face longitudinal off-corner depression of thick slab, as well as the control technology for hot charging crack of micro-alloyed steel slab. This book can be read for the technical developers and scientific researchers engaged in slab continuous casting production of steel, and can also be used as a reference for teachers and students in colleges and universities of related majors.

font-family: 'Calibri',sans-serif;">This book summarizes the formation of solidification defects in continuous casting strand and the process mechanism of improving central segregation, porosity and shrinkage under solidification end reduction.
