为了定量评价常用钢铁材料对环境的影响特征或程度 ,讨论了钢铁材料的环境负荷概念。对此 ,明确定义了等效环境指数 (I)、环境因子 (EF)、环境负荷 (EL V) 3个术语。由此而来 ,可以给出具体钢铁材料的环境影响的定量评价值。这有利于人们正确地使用材料和评价材料。最后计算了某些典型常见钢的环境负荷值 In order to quantitatively evaluate the environmental characteristics or extent of common steel materials, the concept of environmental load of steel materials is discussed. In this regard, the three terms of equivalent environmental index (I), environmental factor (EF), and environmental load (EL V) are clearly defined. As a result, a quantitative assessment of the environmental impact of a specific steel material can be given. This helps people use materials and evaluate materials correctly. Finally, the environmental load values ​​of some typical common steels are calculated
