1982, Liu Hongmin, who just graduated from Northeast Heavy Machinery Institute (predecessor of Yanshan University) majoring in metallurgical machinery, passed the master's degree in this school and continued to study rolling equipment and technology. When choosing his own research topic, Liu Hongmin is faced with a great choice in life. Liu Hongmin deals in the most important steel products.
Study on flatness control theory of plate and strip. Shape is an important quality index of strip, strip mill is the key equipment of strip production, and shape control is the key and difficult technology of large and medium-sized strip mill. At that time, the overall level of shape control technology in China was relatively backward compared with the international advanced level, which restricted the improvement of shape control technology.
The research of flatness theory and control mathematical model lags behind the development of technology and lacks advanced flatness control model. At that time, the basic theory of flatness mainly relied on variational method, three-dimensional difference method, finite element method, boundary element method and other internationally dominant theoretical methods. Facing the lack of independent innovation ability of flatness control theory in China.
In particular, the core competitiveness is not strong and the external dependence is great. Liu Hongmin is determined to take the road of independent innovation that no one has taken before, and use the achievements of independent innovation to promote the development of science and technology, thus promoting social progress and making due contributions to human science and technology for China scholars, even though it may waste a few years or even take greater risks.
After the goal was determined, Liu Hongmin resolutely embarked on the road of independent innovation full of risks, challenges and hopes. After five years of unremitting exploration and efforts, Liu Hongmin finally put forward a new numerical calculation method "strip element method" which has independent intellectual property rights and was first applied to the simulation of strip rolling process during his doctoral study in 1987.
Professor Liu Hongmin and his research group further put forward a complete, systematic and practical theoretical model system of flatness control with strip element method as the core and characteristic, and made great and creative achievements and contributions in the research of theoretical model of flatness control of strip mill, the development of simulation software and the upgrading of engineering technology.
After nearly 20 years of gradual improvement and development, its scientific research project "theoretical system, mathematical model, simulation software and its application" has been successfully applied to Baosteel, Pangang, Hangang, Southwest Aluminum Processing Plant, Southwest Precision Strip Mill and other large domestic iron and steel enterprises, and has achieved great economic benefits, with the economic benefits reaching 200 million yuan in the last five years alone.
The above achievements and contributions of Professor Liu Hongmin have independent intellectual property rights. He enriched and developed the flatness control theory and formed his own characteristics. It provides theoretical basis and digital simulation tools for the research and development of strip mill shape control model. It has made an important contribution to improve the flatness control level of strip mills in China and realize the localization of core technologies.
Liu Hongmin's outstanding contribution to the country and society in the field of scientific research has been fully affirmed by the Party and the country. Professor Liu Hongmin is an expert in government special allowance of the State Council, an outstanding teacher of the Ministry of Education, and a first-class and second-class candidate of the National Million Talents Project 1997. Professor Liu Hongmin has undertaken many national and Hebei scientific research projects and topics, among which the strip element method for simulating the rolling process.
