Regression Analysis of Factors That Influence Strength in Ti Microalloyed High Strength Steel During Thin Slab Casting and Rolling (TSCR) Process

摘要

The regression analysis is applied to analyze the large amount of technological experimental data recorded while producing Ti microalloyed high strength steel during thin slab casting and rolling (TSCR) process. The regression equation of yield strength as a function of the composition (including Ti, N and S), the thickness of casting slab, the thickness of products, the soaking temperature, finish rolling temperature and coiling temperature is developed. It's proved the regression equation is high reliable by statistic significance test and poly-cell approach.
