Improving quality of rimming steel ingots

Likhoradov, A.P. / Beda, N.I. / Katsnel'Son, G.M. / Bembinek, Yu.E. / Evstaf'Ev, E.I.

When bottom pouring open hearth and converter rimming steel in semiclosed ingot molds (small end up), ingots can be covered by concave lids not later than 5 to 8 min after mold is filled; this reduces chemical heterogeneity from top to bottom of ingot and makes it possible to reduce amount of top discard while, in case of low carbon steels of Sv-08 welding type, it greatly reduces loss of manganese; improved rolling conditions at blooming mill obtained. (see also English translation in Stal in English n 4 Apr 1967 p 296-9)
