Abstract

To date, heat to be dissipated in a continuous casting machine is discharged in the environment and not utilized much. A way of saving energy in steel production is replacing the watercooling system with liquid-metal coolant to increase the temperature sufficiently to produce steam and, subsequently, electricity [1, 2]. We identified that lead-bismuth eutectic is the most suitable liquid coolant for continuous casting machines. We performed a simulation of the heat transfer process during steel solidification with various coolants with OpenFOAM. The cooling efficiency is virtually identical for water and lead-bismuth eutectic. The max dissipated heat flux occurs when the inlet coolant temperature is 180 ∘C and the outlet coolant temperature is 400 ∘C. To check the feasibility, we analyzed the steam generation efficiency. It would be ∼ 32 %. For six machines, 6.2 mln. kWh can be generated annually.
