The Modern State of the Blast Furnace Production in Russia
After the stagnation of the 90s Russian ferrous metallurgy has sustained development starting from early XXI century and has been recovering its status and increasing the standards. The pool of BFs in operation is represented by BFs with volumes from 225 m3 to 5,500 m3. Small furnaces are used mainly for making cast iron and ferromanganese. The key development trend is reconstruction of the existing sets by means of increasing their capacity. From 2001 to 2008 average useful volume of the blast furnaces increased from 1767 m3 to 1811 m3, their number decreasing from 62 to 53. It has been made upgrading of the following systems: furnace cooling (copper staves), burden charge (bell-less top charging devices), blast heating (hot-blast stoves by “Kalugin company), blast-furnace gas cleaning (deduster with swirler), additional fuel injection (Premix technology, natural gas heating). Blast furnace melting technology is improving, the new burden material (schungite) is being used. The iron production from 2001 till 2006 grew by 15%. Several blast furnaces in Russia (at Magnitogorsk Iron &Steel Works, at Novolipetsk Steel, at Severstal, at<ZSMK>) are among the world’s best furnaces in terms of specific output and total fuel consumption.
