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
application in the Oregon Steel and in NISCO (China) has
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 Pass 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.
