During a recently completed reline project, Blast Furnace No. 1 operated by Magnitogorskiy Metallurgicheskiy Kombinat (MMK) was converted from cast iron stave cooling to the "Hoogovens" design based on copper plate cooling and high conductivity refractories. Owing to the excellent cooperation with the client's project team, the project was completed and the furnace recommissioned ahead of schedule.
Magnitogorsk Blast Furnace Nos. 1 and 2 were originally built in 1932 as the first two of the eight furnaces that are currently operated at the site. The last major revamp took place in 1998. The furnace was now rebuilt as freestanding and with a 1554 m³ working volume. The intended annual production level stands at 1.4 million tonnes of hot metal.
