Abstract

PURPOSE: To improve slab surface characteristic, make possible the reuse of head frame and improve the yield of blooming by making the head frame of iron having a downward divergent opening, and packing heat-insulating heat-retaining agent in the trace after the head frame has been removed after the formation of the outer shell of the heat part, in an ingot making.
CONSTITUTION: An iron-made head frame 7 of an inner angle θ is installed to the upper part of a mold 1. After the specified amount of killed steel is poured, a top heat-retaining agent 4 is charged through the feed port 11 provided to the upper end face 8 of the head frame. When part of the head 6 solidified and the solidified layer reaches the removable extent of the head frame, the head frame 7 is removed and a heat-retaining agent 8 such as heating material, sand or brick scrap is charged into that trace. This suppresses the formation of the top pipe of the steel ingot.
