| Abstract: | Based on the actual situation of the hot rolled plate production process of Baotou Steel,the chemical composition and process route were designed by computer software JMatPro combined with the experimental research to develop 520 MPa grade BT520JJ wear resistant steel strip.The research show that by using Mn-Ti-Cu micro-alloying and reasonable process,the strip transverse yield strength is 410-439 MPa,the tensile strength is 538-546.6 MPa and the elongation rate is 32.1%-33.6%.Meanwhile,the plate longitudinal yield strength is 409-423.6 MPa,the tensile strength is 533-547 MPa,and the elongation rate is 33.5%,which all meet the standard requirements. |
