青海省钢铁工业物质流分析-西宁特钢（2019）

1）建立2019年西宁特殊钢股份有限公司（西宁特钢）物质流分析表、大气污染物排放表，为区域钢铁行业污染物排放源解析和分配提供支撑。
2）数据来源于西宁特钢官方网站、现场调研和统计数据的综合，基于官方数据和现场调研结果，利用相关行业参数计算获得
3）由于西宁特钢铁矿石原料来源的差异性，计算仅针对2019年的钢铁生产过程
4）西宁特钢是青海省钢铁行业典型企业，其粗钢产量达青海省产量的90%以上，因此数据代表和反映了青海省钢铁行业物质流特征

1) Developed material flow analysis tables and atmospheric pollutant emission inventory tables for Xining Special Steel Co., Ltd. (Xining Special Steel) in 2019, to provide support for regional iron and steel industry pollutant emission source apportionment and allocation.
2) The dataset was comprehensively sourced from Xining Special Steel's official website, on-site surveys and statistical data, and was derived using relevant industry parameters based on official data and on-site survey results.
3) Owing to the heterogeneity of iron ore feedstock sources for Xining Special Steel, the calculation was restricted to the steel production process in 2019.
4) Xining Special Steel is a typical enterprise in the Qinghai iron and steel industry, with its crude steel output accounting for over 90% of the provincial total. Therefore, the dataset represents and reflects the material flow characteristics of the iron and steel industry in Qinghai Province.
