为全面客观地评价钢生产技术的工艺设备及能源的环境影响,研究开发一种热轧钢产品清洁生产技术的环境综合评价方法。该方法采用热轧钢生产的生命周期过程的描述性单元指标,评价从原料到产品、从能源消耗到能源二次利用以及废物的回收利用等对环境的总体影响;采用描述性偏指数,环境影响因子和二次利用偏量来定量分析清洁生产技术对热轧生产过程的各道工序、各类物质流和能源流的影响。该方法结合物质和能源对环境的综合影响,可用于定量比较多个钢铁生产工艺过程的工艺和新产品环境友好性评价。
In order to comprehensively and objectively evaluate the environmental impact of process equipment and energy sources in steel production technology, a comprehensive environmental assessment method for the clean production technology of hot rolled steel products is researched and developed. The method uses the descriptive unit indicators of the life cycle process of hot rolled steel production to evaluate the overall environmental impact from raw materials to products, from energy consumption to secondary energy use and waste recycling; using descriptive partial index, environment Influence factors and secondary deviations to quantitatively analyze the impact of cleaner production technology on the various processes of hot-rolling production process, various types of material flow and energy flow. Combining the comprehensive impact of materials and energy on the environment, the method can be used to quantitatively compare the environmental friendliness of new steel products and processes of many steel production processes.
