| 摘要 | Blast furnace apparatus having a shell that is lined with refractory material, and means for reinforcing the shell including gussets secured to the outer surface of the shell and companion gussets fixed to the inside of the shell substantially in alignment with the first mentioned gussets. The companion gussets preferably have openings through them to inhibit overstressing of the companion gussets on expansion and contraction of the shell. | ||||||
| 权利要求 | 1. In apparatus comprising a shell, refractory material lining the shell, and means for reinforcing the shell including a gusset secured to the outside of the shell, the improvement comprising a companion gusset secured to the inside of said shell substantially in alignment with said first-mentioned gusset, said companion gusset being disposed within said refractory material and having openings therethrough that inhibit overstressing of said companion gusset on expansion and contraction of said shell. 2. In apparatus comprising a shell, refractory material lining the shell and means for reinforcing the shell including a gusset secured to the outside of the shell, the improvement comprising a companion gusset secured to thE inside of said shell substantially in alignment with said first-mentioned gusset, said companion gusset being disposed within said refractory material and being apertured therethrough to inhibit overstressing of said companion gusset on expansion and contraction of said shell. 3. The apparatus of claim 2 in which said companion gusset is apertured with at least one opening therethrough, which opening has a closed boundary. 4. The apparatus of claim 3 in which said opening is a generally round opening. 5. The apparatus of claim 2 in which said shell has an upright axis and in which said gussets extend axially of said shell. 6. The apparatus of claim 5 in which said shell includes a generally horizontally disposed ring member having a portion that extends outwardly of said shell and a portion that extends inwardly of said shell, and in which said gusset secured to the outside of said shell is secured both to the outer surface of said shell and to the outer portion of said ring member and in which the companion gusset secured to the inside of said shell is secured both to the inside of said shell and to the inner portion of said ring member. 7. The apparatus of claim 6 in which said gussets are secured to a portion of the shell above said ring member and to the upper side of said ring member and in which the portion of the shell below said ring member is of smaller circumference than the portion above said ring member. 8. The apparatus of claim 6 in which said inwardly extending portion of said ring member forms a reentrant shoulder in said shell and in which said companion gusset is fixed to said ring member above said shoulder. |
