CONVECTOR RING FOR ANNEALING IN A BELL-SHAPED FURNACE OF STEEL COLD-ROLLED BANDS IN ROLLS

摘要

FIELD: metallurgy; annealing of steel cold-rolled strips in rolls .;SUBSTANCE: the invention is dealt with metallurgy. A convector ring for annealing in a bell-shaped furnace of steel cold-rolled bands in rolls contains a disk with a central foramen and the radial ribs, which form circulation channels. The disk is made from elements, that compose its internal, middle and external parts. Its middle part is formed from segment-type elements, and its external part - from sector-type elements fixed on the segments with formation of expansion seams. The radial ribs are located with overlapping the expansion seams from above and from below and welded only to one of the adjacent sectors. The invention allows to increase durability of rings and productivity of the bell-shaped furnace.;EFFECT: the invention allows to increase durability of the rings and productivity of the bell-shaped furnace.;2 cl, 2 dwg
