Danieli Corus contracted to reline MMK BF number one at Magnitogorsk

Russian steelmaker Magnitogorsk Iron & Steel Works (MMK) – the largest single integrated steel works in the Russian Federation – has awarded Danieli Corus the contract to reline the plant's blast furnace number one. 

The scope of the work includes design, supply, installation supervision, cold and hot commissioning supervision and will take place during Q1 2018.

There are eight blast furnaces at the Magnitogorsk site and Danieli says that the relined blast furnace will have a nearly 10% increased working volume once the work has been carried out and compared to the existing design.

According to Danieli, 'the tuyere zone, bosh and belly will be converted from a cooling system based on cast iron staves to the 'Hoogovens' cooling and lining design'. 

The Hoogovens design, says Danieli, is based on machined copper plate coolers in combination with high conductivity graphite and is the only design with the proven capability of achieving campaign lengths in excess of 20 years (regardless of ironmaking process circumstances).

During the relining process, the furnace will be converted from lintel-supported to freestanding.

MMK produces in excess of 12Mt of steel annually.
