Member presentation

SIJ Acroni, d. o. o.

SIJ Acroni is a member of steel division of SIJ – Slovenian Steel Group and is one of the leading producers of stainless steel, wear resistant, high tensile, tool and other special steel quarto plates. Beside quarto plates we also produce non-oriented electrical steel and hot and cold rolled coils in special grades.

The key objective of the long-term vision of the SIJ Group is to work accordingly to sustainable development and circular economy principles. Our operations are based on social responsibility. We are also signatories of the Sustainable Development Charter of the World Steel Association.

In August 2018, SIJ Acroni took over the processing of steel slag in accordance with the principles of sustainable development.

Unprocessed steel slag had no economic value in the past and was mainly stored at the company’s temporary storage site. Steel slag is now classified as a by-product in accordance with EU-REACH regulation.
The final products of slag processing are:
• Steel granulate, which is returned to the electric arc furnace as a steel scrap,
• Ekominit S1, mineral product used for simple engineering constructions,
• EAF C slag aggregate, which is used in road construction.
Certificate of constancy of performance (ZGPro-1, STS, 1+) was obtained for the mineral product Ekominit S1. Certificate of conformity of the factory production control (CPR, SIST EN, 2+) was obtained for EAF C slag aggregate.
