The first coke was obtained at a unique coke battery in Cherepovets
In early December, PJSC Severstal received the first batch of coke from unit No. 1 of coke battery No. 11 with the technology of ramming coal charge at the Cherepovets Metallurgical Combine. The new unit, with a capacity of 700 thousand tons of products per year, will increase coke production for increasing volumes of cast iron and, accordingly, steel.
Russian metallurgists are introducing a coke battery that is unique in its characteristics, which makes it possible to obtain higher-quality coke in a more environmentally friendly way with the possibility of using low-value grades of coal.
According to Alexander Shevelev, CEO of Severstal, the coke oven battery No. 11 project, worth more than 34 billion rubles, meets market trends.
The general contractor of the construction was "Trust Koksokhimmontazh". As noted by Sergey Fufaev, General Director of Trust Koksokhimmontazh: "The introduction of coal charge ramming technology is an investment innovation that will improve the environmental performance of production and improve the economics of the project, since now metallurgists can use a wider range of raw materials."
In addition, another innovative technology has been used in the construction – a pressure monitoring and stabilization system in each individual chamber of the coke oven battery during the entire coking process, which reduces unorganized emissions and regulates the distribution and removal of flue gases to neighboring chambers. The battery complex is equipped with dust-free coke delivery systems from the chambers, as well as smokeless loading.
According to its technological and economic indicators, the new facility has no analogues in the country, because it maintains high quality of coke when using raw materials with lower cost and quality. And all this while obtaining more environmentally friendly production, which is very important for many industrial cities.
"Due to the fact that there are no such batteries in the Russian Federation, we needed more serious and in-depth training of personnel, equipment and equipment. Trust Koksokhimmontazh has built a new battery, installing over 2.5 thousand tons of the latest equipment. We managed to combine the accumulated experience and advanced technologies, thanks to which the construction time of the facility was reduced by more than 30 percent from the standard.
It is very gratifying that we have coped with all the assigned and unplanned tasks, and erected a new facility in just 24 months," said Alexey Bachurin, head of the KHM-Cherepovets Directorate
