SN 440-72 Based on the analysis of the experience of the construction of many domain furnaces, for a complex of a domain furnace with a volume of 3240 m, the total duration of construction with the preparatory period is 22 months, the development of the last year- 50% of the volume of construction and installation work and the transfer of equipment for installation from 8- th for the 18th month, therefore, the complete issuance of equipment in the installation of a domain furnace with a volume of 5037 m3 should also be completed throughout the complex four months before launch, no later than August 1974. In order to ensure the commissioning of a unique blast furnace within the prescribed time, it was necessary to carry out, especially in the fourth quarter, greater organizational and technical work.
