Abstract


Due to the restrictions of the traditional concepts and industry practices and standards , the adjustment of the mechanical properties of the changes in the composition lead to similar performance materials with different chemical composition , the steel class range . On the one hand the adverse production of steel-making organizations , to increase the consumption of human resources ; On the other hand failed to take full advantage of the fine grain of the steel material composite strengthening mechanism , can not fully develop the inherent potential of the steel material properties . Proceed from the iron and steel product standards , consider merging with the same or similar mechanical properties of steel grades , rolling and cooling process of adjustment to achieve flexible relegation rolling with a reduction of component blank , \\Due to the diversity of customer demand , iron and steel enterprises kinds of steel grades may correspond to several components control requirements tapping mark . At the same time , the adjacent level of mechanical properties of steel grades in the same series , such as X46 , X52 and X56 , the mechanical properties is not very different , and the difference in chemical composition mainly due to one or two major components ; different series or different standard in the same level of mechanical properties , such as 510L and X52, Q235B SS400, basic mechanical properties at the same level , the chemical composition has a large intersection . Therefore, the most important issue for intensive production is merge intelligent steels . Merge objects by a reasonable choice of steels , steel products standards and internal control standards , combined with on-site production data statistical analysis , this paper establishes an intelligent steels merge system , the S \u0026 P Meishan Steel 1422mm hot strip production line carbon structural steel series merge . Series of Pipeline Steel Series ( X46 , X52 and X56 ) and structural steel ( SS330 , SS400 and SS490 ) from product standards the preliminary merger analysis . Blank after the merger within the scope of the ingredients , through the use of TMCP ( thermo-mechanical control ) technology , that is, the adjustment of rolling and cooling process , the X52 , SS400 flexible the relegation rolling , from the point of view of the experimental validation of the intensive production technical feasibility .
