A modernized aluminum wire annealing furnace, equipped with a heat-proof furnace fan designed by OJSC "VNIIMT, was put into operation at the cable plant.
As a result of the furnace modernization, the uniformity of annealing has increased and it became possible to reduce the annealing temperature by 50Ñ from 380-390C to 330-340 C, as well as the holding time in the furnace by 30 minutes from 180 to 150 minutes.
The annealing has become uniform on all three wire coils (difference in relative elongation is within 5%), in contrast to furnaces No. 1 and No. 3, where this difference reaches 30%.
The productivity of the modernized furnace equipped with OJSC "VNIIMT" design fan has increased by 17%
