| 数据集使用建议 | 使用此数据集时，用户应考虑“摇篮到大门”的系统边界，并纳入材料运输、配料、混合、煤气准备、干燥、烧结、浸渍、烘烤、粗磨、箍接、装配、精磨、润滑和包装等Al2O3-C耐火材料生产过程。请注意，不包括生产设备制造和厂房建设的环境影响，因为它们被认为具有相对较低的环境影响。进行生命周期分析时，此数据集的用户应确保包含这些边界条件，并且如果要考查产品的完整生命周期（“摇篮到坟墓”），可能需要调整或补充其他数据。 |
| 产品或过程的技术目的 | 本数据集代表的铝碳质耐火材料主要用于冶金工业中的高温炉衬里。这些材料因其高热稳定性和对熔融金属的化学反应抵抗力而是钢铁制造过程中构建炉炉所必需的。本研究中的Al2O3-C耐火产品特别用于炉衬的绝缘性能，其中耐久性和耐高温性能至关重要。 |

| 采样程序 | A refractory company in Jinan, Shandong Province, was selected for case study in this research. At present, the company produces 30,000 tons of Al2O3–C refractory products annually. These are sold to more than 50 large- and medium-sized enterprises in different provinces of China. The production and sales volume of refractory products of this company ranked first in China in the past 10 years. The company has about 400 employees and covers an area of about 40,000 m2. | ||||
