Pages of the enterprise chronicle ‒ engineering solutions

Abstract

The history of the Makeevka Metallurgical Plant is considered on the examples of the most important and striking technical decisions made by the engineers of the enterprise within the framework of the blast furnace, open-hearth and rolling industries. With regard to blast furnace production following developments are noted: enlarged assembly of blast furnaces and auxiliary units; the launch in 1929 of the largest blast furnace in the USSR with a volume of 842 m3, which served as a prototype for the design and construction of large furnaces at other enterprises; achievement of the best indicators in the country in terms of the useful volume utilization factor; launch in 1957 of blast furnace No. 5 with a volume of 1400 m3, the largest at that time in the USSR; realization of industrial use of coke oven gas in blast-furnace production. With regard to open-hearth production following achievements are noted: the first experience in the USSR in mastering a floor filling machine; the complex of solutions that ensured victory in the All-Union competition of metallurgists for the best quality and low cost of products; leadership in the development of chromium-magnesite domes and evaporative cooling of furnace elements; establishing of the world record for steel smelting at a 200-ton unit. In the field of rolling production, the development of the first Soviet blooming is noted. The current struc-ture of the plant is presented, which is currently based on the production of wire and long products on unique aggre-gates: a wire mill 150 and long products rolling mill 390. The role of the Donetsk National Technical University in the training of engineering personnel for the Makeevka Metallurgical Plant, from 1921 to the present, is noted
