Abstract
Steel enterprises in China are trending to improve material and energy conversion effect, because they are facing with great challenges including energy saving and emission reduction, quality and efficiency improvement. According to the theory of metallurgical process engineering, with the process data in steel manufacturing, some novel indices are designed for quantifying the conversions in different metallurgical unit processes. By analyzing common technologic characteristics in different units, the main manufacturing units are divided into two categories: metallurgical reaction unit and other manufacturing unit. The novel concepts named as “material dissipation rate of unit process”, “material accumulation rate of unit process”, “enthalpy change of unit process” and “energy dissipation rate of unit process” are proposed for describing the effect and dynamic characteristics of the conversions in manufacturing units. Finally, material dissipation rate and energy dissipation rate in unit processes are calculated and analyzed respectively with the real-world process data from a steel plant in China.
