基于理论假设的钢铁制造流程能耗及碳排放分析

Analysis on Energy Consumption and CO_(2) Emission of Iron and Steel Manufacturing Processes Based on Theoretical Hypotheses

随着国家碳减排政策的实施和推进,钢铁行业节能减排压力日趋严峻,但受限于钢铁制造流程的复杂性,对不同冶炼流程进行系统的能耗及碳排放对比分析十分困难。本文对现有钢铁冶炼流程中主要工序进行理论的简化假设,运用理论能耗及理论CO2排放计算方法搭建出各工序的能耗模型和CO2排放模型。通过计算机编程实现工序及典型钢铁冶炼全流程的能耗仿真,从而分析不同原料结构、冶炼工艺及铸轧技术对全流程理论能耗及理论CO2排放的影响,为钢铁企业追求极致能效,钢铁工业推动流程再造提供理论支撑。

With the implementation and promotion of the carbon emission reduction policies in our country,the pressure of energy conservation and emission reduction in the steel industry has become increasingly severe.However,due to the complexity of the steel manufacturing process,it is very difficult to make a systematic comparative analysis of energy consumption and carbon emissions in different steel making processes.This paper carried on theoretical simplification hypothesis of major individual-processes in iron and steel manufacturing processes,and built models of major individual-processes through calculation methods of theoretical energy consumption and CO2 emission.Energy consumption simulations of individual-processes and typical steel making processes are realized through computer programming to analyze the effects of theoretical energy consumption on steel making processes and theoretical CO2 emission under different raw material structures,smelting processes and casting rolling technologies conditions.It provides theoretical support for steel making enterprises to pursue the ultimate energy efficiency and for steel industry to promote process re-engineering.
