| Abstract: | It is introduced the process opitimization fectively controls the harmful residual elements in of BTH60 steel tor cryogenic weld wire steelu ei- steel and alloy elements according to the grade of steel characteristics, it implements the system optimization, the refining slag inclusion degeneration treatment technology and controlling technology of nitrogen through analyzing the deoxidization mecha- nism. Its production process is gradually formed based on reasonable application of non met allic in- clusion technique and controlled -rolling. It implements low content of P, S, O, N in steel and low level of inclusions, it meets the product composition, mechanical properties, low temperature impact toughness and inclusions, it has gradually formed a stable BTH60 production process route, product quality is stable and high performance, it meets the requirement of users. |
