Ilyich Iron and Steel Works

Metinvest innovations took all-Ukrainian acknowledgements

24 April 2012

Metinvest - the vertically-integrated mining group of companies – has received a special award in the all-Ukrainian contest “Invention of the Year-2011” for its innovative product “The Method of Producing High-Strength Steel Double-Seam SAW Pipes for Main Pipelines” developed by PJSC “AZOVSTAL IRON & STEEL WORKS” and by PJSC Khartsyzsk Pipe Plant. PJSC “Ilyich Iron & Steel Works of Mariupol” of Metinvest Group also became the win-ner in the nomination “The Best Invention-2011 in the Region” for the complex of useful models for BOF heat.

Receiving the patent on the invention «The Method of Producing High-Strength Steel Double-Seam SAW Pipes for Main Pipelines» is the first experience of simultaneous patenting the industrial technologies of two metallurgical conversions — rolling and pipe manufacture. Novelty of the design lies in the sequence of technological conversions at the both of Metinvest steel works with the purpose of receiving the finished product — the double-seam SAW pipe for main pipelines produced from high-strength heavy plates. The innovative pipe fully conforms to the set of requirements for the given physical-and-mechanical properties. This product enjoys a great demand in a worldwide construction of steel pipelines for long-distance transportation of natural gas and oil, i. e. from the place of their extraction to the consumption areas.

In addition, State Service of Intellectual Property of Ukraine has issued the patents for two developments by PJSC «Ilyich Iron & Steel Works of Mariupol» — «The Method of Lime Discharge during BOF Heat» and «The Method of Slagging in Basic-Oxygen Converter». Application of these technologies makes it possible to increase the lining resistance of the converters, to control and adjust the important parameters during BOF heats (speed, temperature, impurities effect), which results in considerable reduction of prime costs of converter steel and in considerable improvement of its quality.

Metinvest approach to development of innovative products for new industrial segments of the market is based on the conformity to the requirements and expectations of the customers. The company strives for becoming the best in terms of client centricity, its products quality and service.
