Bottom refractory performance in consteel and top charged DC furnaces

摘要

Nucor Steel-Darlington started up Nucor's first DC arc furnace on January 15, 1985. It was the first DC melter in the U. S. and the first in a steel mill worldwide. Since that time, five additional DC furnaces have been put into operation by Nucor with a combined output of 5,800,000 tons per year. These installations are listed in Table 1.
