ArcelorMittal Kryvyi Rih conducts testing of sinter machine after reconstruction

ArcelorMittal Kryvyi Rih is implementing a program of large-scale modernization of the sinter plant No. 2 with an ecological focus. This is one of the key investment projects of the company, which will significantly reduce the industrial load on the region and the city. To date, five of the six sintering machines of the shop have been modernized: No. 1, 2, 4, 5, 6. Each - with the introduction of a modern system of gas cleaning, aspiration and automation.

Last fall, the company reconstructed sinter machine No. 2, which is currently undergoing hot tests. During the modernization of the sintering machine, the gas purifiers and the incendiary furnace were replaced with a more modern and energy efficient sintering trolley with an increase in the sintering layer up to 450 mm. Also, a new electrostatic precipitator was built and a complete replacement of the sintering machine gas system, linear cooler and its blowing fans was carried out. New double-cone gates and a closed-type dust conveyor are installed on the gas manifold to prevent dust. In addition, the buildings and structures included in the sinter machine complex No. 2 were repaired.

During the work, new effective systems for aspiration and automation of the technological process were introduced. This will significantly reduce dust emissions from the sintering machine and achieve higher productivity and equipment reliability.

After reconstruction, new gas cleaning equipment and electrostatic precipitators made in Italy and Denmark have already been installed on four sintering machines of sintering shop No. 2. Also installed are new incendiary horns with an energy efficient ignition system, which helps to reduce the consumption of natural gas. As a result of the renovation of the second sinter shop, dust emissions from each of the six sintering machines will be reduced by 250 tons per year. The total cost of the project for the reconstruction of sinter shop No. 2 is more than $ 180 million.
