The first printing of this book in Chinese edition was completed in May 2004. The book is summarized my understanding and cognitions about metallurgical engineering. Since 1990, I have come to see that the analyzing-optimization of the functions of many procedures at steel plant has been occurred, which has been resulted the coordinating-optimization between upstream and downstream procedure and the restructing-optimization of whole steel manufacturing process has been brought. It has been led to the changes of dynamic-operation mechanism and the mode of steel plant by above evolution and optimization. Analysis-integration method should be used for studying the contents.
Thanks to support from the Baoshan Iron & Steel Co. Ltd (Baosteel), the first distribution took place in Shanghai on May 28, 2004,a memorable event that remains fresh in my mind. Thereafter, the Baosteel leadership, which had evinced close concern for the contents of the book, specially organized a study class voluntarily attended by about a hundred engineers and technicians. Starting in July 2004 and ending in May 2005, I gave a total of twelve lectures at the rate of approximately one per month. On May 12 and 13, a summing-up seminar was held at which eight experts at Baosteel delivered a number of vivid and variegated academic reports, supported by visual displays, in connection with the production, construction, and technological reforms at Baosteel. All these reports were of a high caliber and quite stimulating. On the following day I gave a summing-up discourse.
These lectures held by Baosteel helped me shed two misgivings that had been bothering me before the book’s publication. One was an apprehension that the book’s contents were too difficult to understand, that some of its readers might not be well-grounded enough to accept certain views and arguments since these had never been touched upon during their college educations, and because in-depth comprehension requires a broad range of knowledge on the part of the readers. The other was that readers would not be interested, as the book often places emphasis on physical fundamentals, on analyses and integration, rather than on the resolution of individual matters confined to specific issues. However, the Baosteel series of lectures demonstrated that modern steel enterprises need theoretical knowledge regarding flow process engineering, or in other words, that such knowledge is necessary for the modernization and revamping of the steel industry.
The publishing of this book also drew the attention of a number of research institutions, such as the Institute of Process Engineering of the Chinese Academy of Sciences,Central Iron & Steel Research Institute (CISRI) and University of Science & Technology Beijing (USTB). Several institutions of higher learning invited me to give academic reports, and some universities even set up elective courses for postgraduates. The book also triggered interest among relevant experts at steel designing institutes, and the Capital Engineering & Research Incorporation Limited repeatedly invited me to deliver special-topic reports.
It is pointed out that from the viewpoint of physical essence of steel manufacturing process, multi-factor matter “flow” (mainly ferruginous matter flow) driven by carbonaceous matter flow, operates in a dynamic and orderly manner in accordance with given “programs” and within a complex “network structure”. So, the function of steel plant should be developed as:
1. Operation function of ferruginous matter flow—the functions of steel product manufacturing.
2. Operation function of energy conversion—the functions of energy conversion and the functions of waste treatment and recycling related to surplus energy.
3. Inter-action function of ferruginous matter flow and energy flow—realizing the target of process technology and related functions of waste treatment and recycling.
Here, I would like to point out the characteristics of the book:
•It outlines a theoretical study of the energy sources and operational dynamics mechanisms of metallurgical process operations, the purpose being to reveal the essence and regularities of the whole metallurgical manufacturing process in order to optimize the flow of materials, energy, and information in the course of steel plant manufacturing.
•It presents studies of the “three elements”—flow, process network and program—metallurgical process operations, the purpose being to minimize dissipation in the course of such operations so as to enhance the market competitiveness of steel plants and their ability to maintain sustainable development.
•It lays theoretical emphasis on dynamic and orderly operations in the metallurgical process, the purpose being to devise quasi-continuous/continuous operations in the metallurgical process so as to raise the technical and economic indexes of steel plant operation.
•It outlines a theoretical study of the integrated structure of the metallurgical manufacturing process, the purpose being to enable the setting up of a new generation of steel plants by optimizing the overall course and overall functions of the metallurgical process through integrated innovations;.
