Abstract
Continuous casting technology is extensively used in steel production. Refractory materials made from alumina–carbon
(Al
2
O
3
–C) are integral to the continuous casting process to ensure high-quality steel product. However, the production of
Al
2
O
3
–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 Al
2
O
3
–C refractory pro-
duction process in a Chinese factory. The study analyzes the environmental impact and fnancial cost of Al
2
O
3
–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 Al
2
O
3
–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 Al
2
O
3
–C refractory production separately. Sintered corundum
and coal are the key materials with signifcant environmental impact. They constitute 44.4% and 11.3% of the total envi-
ronmental impact load, respectively. Sensitivity analysis shows that the batching process has a higher optimization priority
than the coal gas preparation process. The fndings point toward more sustainable methods to manufacture for Al
2
O
3
–C
refractory materials.
