PJSC Magnitogorsk Iron and Steel Works has completed the construction of aspiration systems for casting beds at blast furnaces No. 9 and No. 10. The project with CAPEX of over RUB 1 billion allows dust emissions to be almost completely disposed of, decreasing the emissions 50-fold.
The aspiration system for casting beds at blast furnace No. 10 has come into operation in the run-up to “Day of the Steelworker”, and in August No. 9’s system will be commissioned. The devices capture the dust that is emitted in the casting beds of MMK’s most powerful blast furnaces. The total reduction in emissions will be 640 tons per year. The new aspiration systems not only help to achieve environmental targets, but also improve the working conditions for MMK’s blast furnace workers.
The aspiration systems at the casting beds of blast furnaces No. 9 and No. 10 are made up of similar electric filters, engineered by the group “KondorEco- SFNIIOGAZ” (Semibratovo, Yaroslav region). The electric filter has two sections and four components, which make up its considerable size. Its dimensions are: 10 meters in height, 20 meters in width, and 15 meters in length. The overall height of the electric filter combined with the steel structure exceeds 30 meters. The electric filter has a productivity level of 800,000 cubic meters per hour and a 95% purification efficiency.
The construction of the aspiration system at the casting bed of blast furnace No. 10 started in December 2016, the construction for No. 9’s system began in February 2017. The projects’ CAPEX was RUB 595 million each. More than 1,000 tons of steel constructions and 500 tons of gas-purifying facilities were assembled together over the construction period. JSC “PO Montazhnik” acted as the primary contractor. The general designer was PLC “Magnitogorsk Gipromez”. (MMK/Ukrainian metal)
