ArcelorMittal Kryviy Rih has increased product quality, reducing losses by UAH 100 million in October 2018 to April 2019 from a special initiative taken last year to monetize and eliminate losses from the production of defective products at all stages of metallurgical production. Head of the quality department at ArcelorMittal Kryviy Rih Ms Elena Gudimova said “Since October last year, we have been measuring losses not only in tonnes of substandard products, but also in hryvnas spent on eliminating technological deviations at all intermediate production stages. For example, steelmakers have received from the blast furnace workers cast iron with low temperature, high sulfur and silicon content. In order to get steel with given properties from it, one has to use expensive additives, spend more energy, increase the melting cycle, etc. Now all these costs with deviations are calculated and losses are eliminated. Thus, the costs of production of pig iron with deviations in March are reduced by 30% in hryvnia equivalent compared with November 2018. Another example is that in the first quarter the number of non-graphic melts decreased three times, as a result of which the metal does not meet the specified properties of the buyer, is removed from the direct order and goes to the warehouse until the time of sale. The company managed to reduce non-graphic melts by optimizing the process of preparing ladles and blocks for purging with argon.”

She added “Loss analysis is carried out across the entire technological chain of metal production, including aggregates, workshops and products. Risks are also evaluated for high-quality products. Additional control is installed in the areas for receiving the final product. In addition to the control officers of the Quality Control Department, the team-mates for moving the rolled products and the stackers responsible for loading metal products were asked to identify the defects.”
