Interaction mechanism among material flows, energy flows and environment and generalized thermodynamic optimizations for iron and steel production processes

“…(图6~8) [127] 以及广义构形优化(图9) [127,128] . 以钢水产量 最大、能耗和排放最小等为目标, 废钢用量为优化变 量, 考虑了原料总成本约束条件, 对转炉炼钢过程和工 序(图10)进行了广义构形优化 [129] 和有限时间热力学 优化(图11) [130] . [91] 的基础上, 以 耗散最小为目标, 绝热层厚度为 优化变量, 考虑了绝热层体积约束条件, 对不同传热 边界条件下的4种轧钢加热炉壁绝热层(图20) [91,186~189] 进行了构形优化(图21).…”

Generalized Thermodynamic Optimization for Iron and Steel Production Processes: Theoretical Exploration and Application Cases

“…Rajashekar et al [63] used the iron ore slime as the coolant of the steel-making procedure, and obtained the economic and ecological-resource benefits from this innovative practice. Similar to the works in [59], constructal theory was introduced into the optimization for the converter steel-making elemental package [64]. As shown in Figure 19, a converter was taken as research object, generalized constructal optimization for a converter steel-making process was performed by taking the maximum molten steel yield as objective.…”
