Melt-down mechanism of softening-melting layers in Hirohata No. 1 BF (blast furnacc) is examined. As the results with the upper part of “root” (the lower part of softening-melting zone, the end of which contacts with the furnace wall), heat of fusion is considered to depend on the reduction rate (R.R.) of softening-melting layer. The values are about 3×103kcal/t-softening-melting layer with R.R. -50%, 8×103kcal/t with R.R. -70% and 31×103kcal/t with R.R. >70%. From these values and calculated melt-down volume at “root” of Hirohata No. 1 BF, heat transfer coefficient for melt-down of “root” is obtained. By applying the relation to the estimated softening-melting zone in Kimitsu No. 3 BF, melt-down volume agrees approximately with the heat transfer quantity. Melt-down of inverse V-shaped softening-melting zone is concluded to occur by this mechanism.
