Austria/Australia: Refractory producer RHI Magnesita and Calix say they have started a memorandum of understanding to develop a flash calciner for use in the production of refractory materials, to enable CO₂ separation for either utilisation or storage. The companies have agreed to run studies up to and including basic front-end engineering and design for a commercial-scale demonstration facility at an RHI Magnesita site.

RHI Magnesita and Calix started discussing a collaboration in early 2019. The application of Calix's technology to refractory products has been the subject of pilot scale test work during 2020, with larger scale test work currently underway.

Luis Bittencourt, chief technology officer of RHI Magnesita said, "We are pleased to be working with Calix on this project, which is a key part of the research and development programme on CO₂ emissions reduction that we are carrying out over the next five years. Together with our partners at Calix, we are seeking to develop new technologies for the capture, storage and utilisation of CO₂ that would otherwise be emitted during the refractory production process." Phil Hodgson, the managing director of Calix added that the company was also looking at strategic opportunities in its magnesium oxide businesses.

Germany/Sweden: Refratechnik Group and Sweden-based Höganäs Borgestad Group have started a strategic agreement for the supply of refractory products to customers in Nordic countries. Höganäs Borgestad customers will now have direct access to the product range and application knowledge of the Refratechnik Group. The refractory suppliers said that their arrangement, “underscores the desire of both companies for long-term, sustainable and mutually beneficial partnerships; resulting in a secure supply of top-quality product for the customer.”

Germany-based Refratechnik Group operates refractory and industrial mineral businesses, with over 1900 employees in 27 locations worldwide. Sweden-based Höganäs Borgestad is the largest refractory company in the Nordic region providing installation services and refractory materials to many industries.

Austria: RHI Magnesita recorded consolidated net sales Euro2.26bn in 2020, down by 23% year-on-year from Euro2.92bn in 2019. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) were Euro140m, down by 53% from Euro300m. Pre-tax profit for the year was Euro42.0m, down by 30% from Euro200m.

The group attributed the declines to lower refractory volumes as a result of the effects of the coronavirus pandemic on market demand. It said that customers began re-stocking supply chains at the end of 2020 and into the first quarter of 2021, driving increased refractory demand. Its cement and lime business declined by 21% in 2020. The supplier said that the business recorded a ‘strong performance’ in the first quarter, characteristic of seasonal demand, followed by weak second and third quarters when demand was negatively impacted by the Covid-19 outbreak.

Chief executive officer Stefan Borgas said, “2020 has been the most challenging year that our industry has experienced. Throughout the pandemic, RHI Magnesita has protected the health and safety of our employees, ensured business continuity for our customers and taken initiatives to support liquidity and underpin future profitability. Through one of the severest downturns on record, we demonstrated the resilience of our business model and the outstanding commitment of our people while our strong financial position has enabled us to accelerate investment in our strategic priorities.”

China: The government of Jiangsu province has awarded an Environmental Protection certificate to Imerys subsidiary Calderys’ Zhangjiang refractory plant. The company said that the certification results from years of hard to enhance environmental efforts beyond national requirements. One example of the work is dust-proof partitioning around all dust-emitting equipment.

Environment, health and safety supervisor Ricken Ren said, “In 2016, the plant improved the quality of its raw materials. With major work no longer required to lessen the water content of the materials, it was able to reduce the use of its dry kiln, which uses natural gases in its drying process, in turn greatly reducing the plant’s energy consumption. ” He added, “Keeping the plant’s environmental impact as low as possible is a never-ending job, and we cannot lose focus. We perform daily checks to ensure devices such as our dust collectors are working effectively, and we are always monitoring our emissions during operation according to national laws. Every department worked together on environmental protection performance. It is a great teamwork result.”

India: Denmark-based Hasle has supplied a Hasle D59A coating-resistant castable to Asian Cement for use on the inlet chamber and riser duct at its cement plant. The supplier supervised installation.

Brazil: RHI Magnesita plans to spend Euro30m towards building a rotary kiln in its mining site at Brumado, Bahia. The upgrade is expected to increase the production at the unit by more than 30% as the kiln is designed to process up to 140,000t/yr. The announcement follows a planned investment of nearly Euro40m towards the construction of a new headquarters for its South American operations in Contagem, Minas Gerais that was revealed in 2019.

“This investment in the construction of a rotary kiln with innovative technology will enable us to develop a new portfolio of raw materials, in addition to those already available on the market. The new raw materials include noble sinters at very competitive costs on the international market. This will bring operational flexibility, the ability to offer differentiated value-added products to our customers in the Brazilian market, and will put us in an even more competitive position in the global environment,” said Francisco Carrara, president of RHI Magnesita in Brazil and South America. He added that the group was seeing a ‘considerable’ recovery in the steel and cement segments in Brazil.
