Abstract

Continuous casting technology is extensively used in steel production. Refractory materials made from alumina–carbon (Al2O3–C) are integral to the continuous casting process to ensure high-quality steel product. However, the production of Al2O3–C refractory material itself is the source of a range of environmental problems. Life cycle assessment and life cycle cost methods are applied to compare and analyze the environmental impact and economic cost of the Al2O3–C refractory production process in a Chinese factory. The study analyzes the environmental impact and financial cost of Al2O3–C refractory production in the “cradle-to-gate” system boundary. Monte Carlo simulation was used in uncertainty analysis to ensure the credibility of the study. The results indicate that the key environmental impact categories of Al2O3–C refractory production are: freshwater eutrophication, human toxicity, freshwater ecotoxicity, marine ecotoxicity, and natural land transformation. The batching and coal gas preparation processes are the key processes with remarkable environmental impact. They make up 69.5% and 13.5% of the environmental impact load of the Al2O3–C refractory production separately. Sintered corundum and coal are the key materials with significant environmental impact. They constitute 44.4% and 11.3% of the total environmental impact load, respectively. Sensitivity analysis shows that the batching process has a higher optimization priority than the coal gas preparation process. The findings point toward more sustainable methods to manufacture for Al2O3–C refractory materials.
