ABSTRACT: In this paper, the relationship between
steel and chemical elements is explored. A production record of a steel mill is
adopted for two years, which is used as the basic data to standardize the data.
Then, according to the correlation coefficient method between the hot-rolled
ribs No. 1 and No. 2 hot-rolled ribs, the correlation between the two sets of
data is analyzed. The main influencing factors of the hot-rolled ribs
properties are obtained qualitatively. Then, the logistic regression method is
used. Finally, according to the national standard of Chinese steel, the linear
optimization model of Cr and Mn and V elements was established, and the change
range of Cr was obtained without affecting the performance of hot rolled ribs.
