With the rapid development of world economy, the quality control of products becomes the core and key of competitivenessin the enterprise. The requirements of the complex quality control model are more urgent. Therefore, based on the background of the quality control of steelmaking and rolling material in metallurgy process industry, this paper presents a comprehensive backtracking model of quality control based on the hierarchical. Firstly, analyze the steelmaking and rolling process, then analyze and partition hierarchical operation structure. Secondly, introduce the comprehensive backtracking model, to establishbacktracking model ofthe quality control process. Finally, associatively combine the quality grading hierarchical system structure scheme with backtracking model of the quality control process, and apply it to the actual quality control. Its operation result shows that the classification control and coordination function of the model is good.
