Magnitogorsk Iron and Steel Works’ (MMK) new sinter plant will be equipped with two unique sintering machines which will be the only machines of their kind in Russia. At the moment, the installation of technical equipment on the units continues, as well as steel construction in the key buildings and facilities of the factory. The new sintering machines will have an area of up to 300 sqm for each sintering belts, the height of each sintering layer will be 700 mm. For comparison, at Sinter Plant No 4 (due to be decommissioned after the commissioning of Sinter Plant No 5) the sintering area is 95.4 sqm with a sintering layer height of 280-290 mm. The upkeep of smalls (splinter factions of 0-5 mm) will be reduced from 10% to 5%.

Each sintering machine will be equipped with two electrostatic precipitators which are designed to clean dust off the sinters. In addition, the factory's environmental complex includes nine suction systems with filters and systems to recycle the sinter gases. There are also plans to build a facility for the dehydration of gypsum, as well as a system to collect and remove excess water from the industrial site to put into the sludge enrichment plant in the mining and processing factory No. 2.

“The new project will significantly reduce the factory’s negative impact on the environment: dust and sulfur dioxide emissions will be reduced by 490 and 3,280 tonnes per year, respectively,” said Victor Rashnikov, Chairman of MMK. “Moreover, suspended particles emissions to the circulating water supply system will be reduced by 600 tonnes per year. By reducing the harmful impact, the working conditions for factory workers will be significantly improved.”

The launch of the first sintering machine is scheduled for early February 2019 and the second machine for July 2019.
