Abstract
Hot-rolled ribbed steel bar (HRB) plays an important role in many fields. Chemical components of HRB directly influence tensile strength. Through statistical analysis, we establish linear regression and polynomial regression models (quadratic and cubic) of tensile strength and chemical components of HRB400 in China. So we can control the production of HRB400 to ensure the tensile strength by adjusting the contents of chemical components.
