PAO Severstal, one of the world's leading vertically integrated steel and mining companies, is upgrading measuring probes on converters in the converter steel smelting shop of the Cherepovets Steel Works (part of the Severstal Russian Steel division). This initiative is aimed at increasing the daily volume swimming trunks from 82 to 86.
“It is the investment program that is the main source for us to achieve long-term goals in the upstream direction. At the same time, it is important for us to implement these projects quickly without sacrificing quality. The introduction of new measuring probes, which will simultaneously evaluate the temperature of the steel in the converters during their blowing, will increase the reliability of the units, reduce the overconsumption of ferroalloys on the carbon assortment and reduce the duration of the smelting cycle by 30 seconds. This event meets the goals of one of the company's strategic priorities - Cost Leadership, commented Vadim Germanov, General Director of the Severstal Russian Steel Division.
New probe designs with better performance, maintainability and reliability provide a guaranteed opportunity to obtain parameters metal regardless of the number of measurements in the purging process without knocking down the converter. The main process equipment for the measuring probes will be supplied by Daieli Corus V.B. (Netherlands). Now the company's specialists have begun to develop basic engineering - the documentation required to start manufacturing equipment and developing working documentation. The introduction of new measuring probes into the technological process is planned in stages in 2020.
An increase in the volume of steel produced will also become possible due to the new design of the converter lining, which will increase the life of the units from 5.5 to 6 thousand heats. The pilot version of refractory masonry in the new design is planned to be launched in October this year at converter # 1, which will increase the production volume by 45 thousand tons.
