RHI Magnesita’s Low CO2 Gunning Mixes
RHI Magnesita has been developing sustainable refractory solutions, focusing on gunning mixes that incorporate circular raw materials to reduce the carbon footprint. Our efforts have resulted in gunning mixes with a 30 -85% reduced carbon footprint in EU, CIS, and Türkiye, reducing customers’ Scope 3 CO2 emissions. This initiative is part of a broader commitment to sustainability and environmental stewardship in the refractory industry.
About the ANKERJETY- Series
RHI Magnesita’s ANKERJET Y line, a well-established brand in sustainable gunning mixes, is based on MgO-C circular raw materials. Currently, the brand is produced in Veitsch and is mainly available for the European market. The portfolio includes eight distinct product variations, specifically designed for use in EAF, BOF, and steel ladles, ensuring optimal performance.
ANKERJET YW12-AT stands out as an innovative recycling solution that replaces traditional sintered magnesia formulations with a cutting-edge circular MgO-C concept. It is designed for the hot repair of ladle linings through direct gunning, which has proven to be one of the most effective methods for extending ladle lifespan. The ANKERJET YW12-AT gunning mix incorporates up to 30% circular raw material, successfully displacing traditional brands without any loss of performance.
From Development to Successful Implementation
RHI Magnesita has successfully introduced the innovative ANKERJET YW12-AT brand at a key customer site in Southern Europe, marking a significant advancement in sustainable refractory management. This initiative is part of our commitment to circular economy practices, as RHI Magnesita manages total refractory solutions.
In a groundbreaking test conducted with 100-ton ladles, the product demonstrated excellent adhesion, minimal rebounding, and superior heat management capabilities—performance that met and exceeded expectations.
Over five days, a dedicated team conducted extensive testing, applying 24 tons of the material across 12 ladles and 21 different application samples. The results were compelling, with operators reporting that ANKERJET YW12-AT adheres better than conventional products, even under more challenging conditions in the slag line of the ladle.
The positive outcomes have prompted the steel plant managers to authorize a transition in their product portfolio. Beginning June 2024, ANKERJET YW12-AT has started to replace traditional products as the standard offering, allowing for the substitution of 900 tons of conventional material with a circular solution. This shift is projected to prevent approximately 500 tons of CO2 emissions annually, equivalent to 12 turns by truck around the world!
By adopting ANKERJET YW12-AT, customers can reduce their CO2 emissions by up to 30% per ton of installed material compared to virgin brands. This innovative solution represents a transformative step in the market.
