ABSTRACT

The microalloying method is most widely used in the production process of high strength steel bars. However, its cost factor has become the main bottleneck for its difficult promotion. The incomplete structure of analytic hierarchy model is established in this paper to identify the primary and secondary elements affecting the performance and investigate the influence mechanism. The dominance numbers are especially introduced to revise the final weights. Hence under the premise of ensuring the mechanical properties of the steel bars, the cost is controlled by increasing the input of certain elements and reducing the use of other expensive micro-alloying elements.
