4. Characteristics and advantages of the model and software(1)

The advantage of the technology is that it has filled the technology gaps in the world; its advancement exists in that, it has used world’s first-class models to upgrade the software that has always been world’s first-class!

This technology has been developed in the past 30 years in Germany and USA by combining advantages of several strongest teams in the world, for example, the early work of Tippins, the upgrade in Evraz Oregon Steel, and the further development by adding metallurgical models and intelligent learning into the system. The successful applications in the Oregon Steel and in NISCO hve fully demonstrated the advancement of this technology.


1, World-class Model
Model development started from a 15-year research project I participated in the Metal Forming Institute in Germany, including over 40 Ph.D. theses. My initial rolling models fand applications in German MDS (now SMS) and the Italian Danieli. So I was invited by Danieli to its Italian headquarters for three times. I published my first book in Germany, and my name also stayed on the University’s website for eight years. Before I completed my Ph.D. study in Germany, I was hired by Morgan in USA as senior engineer in charge of model development. Four years later I was in the unprecedented success of the modeling, and I worked as a software engineer and software consultant for several steel companies. During the further development of the process models, I also attended computer evening training, and within 8 years I completed 30 computer courses, consisting of classes for B.S., M.S., Ph.D. and Microsoft certification, particularly set up for senior software engineers and software architects. This provided me with sufficient skills to transformed the models into software.

This set of models, on the basis of the 15-year of research results in Germany, has been integrated with Morgan’s 5-year rolling mill test data, and Morgan’s hundred years experience around the world with a large number of first-hand data collected. Example of field data collection are such as in 1997, Morgan Engineer lived in Cleveland in a factory for more than three months to collect data. I also visited major libraries in USA, Canada, Germany and China, etc. for published data, and collected field data during my over 200 consulting projects worldwide. In the latest stages, the model has gradually formed three series of more than 100 sets. The three series are on Metal Flow, Force and Energy Demand, and the Microstructure and Mechanical Properties, etc. These series was called the Metal Data Base Model Series. These models have been continuously improved during on-site projects. Up to later rolling mill field projects, they have been uograded as new-generation Level 2 model, including Metallurgical Model, Intelligent Learning and Advanced Software Engineerting particularly Uninterrupted Upgraded. Later in NISCO development, I further developed software to design model coefficients, so nearly 10,000 sets of model files can be automatically designed, for over 150 grades for several thousands model grades. See dozens of papers I published in USA and Germany, etc.
