Name of Notes : – Manufacturing Processes II Lecture Note


Manufacturing process engineering came from the technological development and profound change of the steel industry. Ferrous metallurgy is a process of iron-coal chemical engineering at high temperature. The manufacturing process consists of many procedures and consumes plenty of resources and energy. In some countries with high steel capacities, the energy consumption of the steel industry usually occupies 10% of total consumption or even more.

The supply and prices of the resources and energy therefore have a significant influence on the steel industry. Due to the oil crisis in the 1970s, the technology of continuous casting (CC), instead of ingot teeming, in steelmaking workshops was developed. The connection of blast furnace iron making to continuous rolling process of steel via 100% CC process created the precondition for the quasicontinuous/continuous running of the manufacturing process of steel plants.

The technology of near-net-shape casting further improved the establishment of continuous operating lines in steel plants. Since the 1990s, there had been six important key/common technologies widely applied in the Chinese steel industry: CC technology; blast furnace pulverized coal injection technology; blast furnace campaign elongating technology; the long-product continuous rolling technology; comprehensive energy conservation technology by means of process structure optimization; and the basic oxygen furnace (BOF) slag splashing technology.

The successful application of these key/common technologies provided the physical foundations for the formation of metallurgical process engineering. For example, the quasicontinuous/continuous operation flow for a steelmaking workshop can be realized by coordination of the continuous solidification processing with the high-frequency high-speed periodically batch type converting. However, as the lining refractory life of BOF is short, the slag splashing protection technology has been applied to coordinate the maintenance cycle of BOF with caster, by which the dynamic-orderly operation flow of sequence CC for long time periods becomes realizable.
