Abstract
The effect factors on intensity of cooling of large-scale ESR furnace mold have been analyzed by using heat transfer theory
it is obtained by calculation that the optimum water flow rate for the 1 800 mm diameter mold is 1. 2 m/s
and the optimum design scheme for high speed water case type mold with case layer thickness 10 mm is put forward. The production results by remelting 60 t 0.030C-17.10Cr-ll.80Ni-2.55Mo-0.072N austenite stainless steel ESR ingot with voltage 77. 5 V
current 19 kA
remelting speed 31. 6 kg/min and water rate 1. 2 m/s show that the formability of ESR ingot is better
and the forming quality of ESR ingot is improved with smooth ingot surface and uniform distribution of slag skim.
