RATH presents new, advanced feeder expendables series at ...

RATH is at home wherever heat-resistant materials are essential – and that includes the glass industry. The internationally active Austrian refractories manufacturer offers the complete range of highest-quality materials for the entire glass manufacturing process.

You can find more information on our web, so please take a look.

With more than 130 years of experience, RATH is regarded as a competence leader in the refractory sector. Its customers benefit from the widest range of products and service available on the market, coupled with extensive, industry-specific expertise – which also applies to the glass industry. The specialists at RATH have the required in-depth industry knowledge and understanding of the specifics of glass processing. RATH´s precision-crafted refractory products are designed for a wide range of applications, including container glass, float glass, C-glass, E-glass, and tableware.

At Glasstec in Düsseldorf, RATH will present a new, advanced and exclusively produced feeder expendable series – proving once again that the company attaches high importance to research and development.

The further development of refractory compositions is a challenge that RATH is taking on with great commitment. “After an intensive 5-year research and development process, the new FOURATH 4xx feeder expendable series is ready for introduction at glasstec in Düsseldorf”, said Robert Nusszer, Managing Director of the Sales Unit Glass at RATH. “This new product line is based on an optimized formulation which has been exclusively developed and produced by RATH.”

The product has been put through its paces in the RATH laboratories and has successfully passed the first glass factory trials in the last 1.5 to 2 years.

There is also news from RATH’s production facility for hot gas filter elements in Germany: A second production line is currently under construction at the Meißen plant and is scheduled for completion and commissioning in . The filtration business line on one of the business lines has seen a significant growth within the RATH Group.

“It has great potential since the glass industry has to drastically reduce its footprint on environmental pollution and the greenhouse effect worldwide. RATH is committed to advancing environmental protection and helping its customers in the glass industry achieve their ambitious environmental goals. Thus, RATH continuously develops and invests in this technology”, Robert Nusszer summarized.

Low carbon refractories for the future

PSR has been successful in its application for support for a Small Scale R&D project to as part of the ‘Transforming Foundation Industries’ (TFI) Challenge fund from the UK Government’s ‘Industrial Strategy Challenge Fund’ (ISCF). This project will focus on looking to reduce the length of firing cycles in the refractory manufacturing process.

As a manufacturer of refractories for the container glass industry, PSR falls within multiple energy intensive foundation industries (ceramics and glass).

Current refractory manufacturing methods include long firing cycles where substantial energy savings and corresponding reduction in CO2 emissions could be achieved by reducing the lengths of firing cycles.

This project, in collaboration with Sheffield Hallam University (SHU) and the British Ceramic Confederation (BCC), aims to find a cost-effective solution to reduce energy consumption in the refractory manufacturing process. The addition of dopants to densify the material will be investigated to enable firing at lower temperatures or for shorter times, reducing energy consumption and CO2 emissions. Based on a literature review we believe that >10% savings are achievable in the refractory manufacturing process.

Simon Parkinson, Managing Director at Parkinson-Spencer Refractories said:

“We’re delighted that this project has been given the go ahead and look forward to work ing with Sheffield Hallam University and the British Ceramic Confederation to research low carbon refractories. Whilst we always strive to optimise production and minimise CO2  emissions, this exciting and ambitious project aims to make a step change in energy efficiency in the refractories industry.”

The project will benefit PSR through knowledge transfer with partners, and opportunities to co-create new concepts; transfer best practice through industry and academia partnerships; and improve the energy efficiency of the refractory manufacturing processes.

There are potential savings across the UK and global refractories industries if this technology were licensed and applied more widely. A 10% energy and CO2 saving across the relevant products within the global refractories industry would save up to an estimated 5 MT / year.

Jon Flitney, Energy & Innovation Manager at BCC, commented:

“BCC is delighted to be supporting PSR and Sheffield Hallam University with their project to develop novel additive technologies to enable faster and / or lower temperature firing of refractories. We look forward to supporting the dissemination about both the project and wider learning about the funding landscape to the UK ceramics sector.”

Paul Bingham, Professor of Glasses and Ceramics at SHU, said:

“SHU is pleased to be supporting this project designed to enable our foundation industries to achieve their important decarbonisation goals, via new and novel technologies for more rapid, lower-energy firing cycle.”
