钢铁生产实际上是铁—煤化工过程及其深加工过程,其物理本质是铁素物质流、碳素能量流和信息流的输入输出问题。钢铁工业铁素物质流的功能是钢铁产品制造功能,能量流运行的功能就是能源转换功能以及剩余能源如何高效利用。因此,钢铁制造流程要实现的功能有三个:钢铁产品制造功能、能源转换功能和废弃物消纳
Iron and steel production is actually iron-coal chemical process and its deep processing. Its physical essence is the input and output problems of ferrite flow, carbon energy flow and information flow. The function of the ferrous material flow in the iron and steel industry is the manufacture of steel products. The function of energy flow operation is the energy conversion function and how to use the remaining energy efficiently. Therefore, there are three functions to be achieved in the steel manufacturing process: steel product manufacturing functions, energy conversion functions and waste disposal
