How to maximize the service life of feeder expendables by avoiding typical installations errors: RATH shares its extensive expertise at Glassman Latin America

In the container glass industry, minimizing machine downtimes is a top priority in order to achieve high productivity. At Glassman Latin America, international refractories manufacturer RATH will be sharing its comprehensive knowledge on how to maximize the service life of feeder expendables from a refractory perspective and thus prevent machine downtimes.

It is well known that high-quality refractories are the basis for superior glass conditioning in all areas of the glass making industry. Their use in forehearth and feeder mechanisms plays a crucial role in the formation and conditioning of glass prior to being formed into the finished product. All RATH refractories are formulated from the highest quality raw materials and designed to achieve predictable density and resistance to erosion and corrosion. “However, to achieve good refractory performance, we must always bear in mind that feeder expendables are sensitive, high-purity and fragile products, and must be installed according to the refractory manufacturer’s guidelines to avoid installation errors that lead to machine downtime”, says Robert Nusszer, Head of Sales Glass, RATH Group, who will explain how the service life of feeder expendables can be maximized from a refractory perspective in his expert lecture at Glassman Latin America. The presentation by the proven expert on refractories for the glass industry will also provide specific recommendations on how to avoid typical and serious installation errors.

RATH presents FOURATH®4, a new advanced feeder expendables series

At Glassman Latin America, the international refractories manufacturer will present FOURATH®4, a new, advanced range of feeder expendables based on an optimized formula developed and produced exclusively by RATH. During the R&D process, RATH selected the highest quality raw materials to keep the impurity level to a minimum and achieve the lowest possible glass corrosion, infiltration, devitrification, and blistering rate. To be more competitive on the market, the entire manufacturing process was converted from clay-bonded slipcasting to chemically bonded vibrocasting. This brings some significant advantages to RATH customers. First of all, the product quality is improved, with better corrosion, infiltration and devitrification resistance, better thermal shock and crack resistance, and longer service life due to a more compact mix, better surface quality, significantly lower porosity and higher CCS. Secondly, the new manufacturing technology avoids additional grinding of the tube’s outer surface while maintaining the tight tolerances. “This enables us to increase the service life of the tube and significantly reduce cracking in the tube by eliminating the micro-crack formulation during machining,” Robert Nusszer says. In cooperation with several customers, FOURATH®4 has successfully passed the first trials in glassworks over the last 2-3 years. “Customer feedback on theproduct performance of the FOURATH®4 series confirms its high level of efficiency and quality in glass production,” Nusszer adds.

Providing comprehensive support to the glass industry in its sustainability efforts remains high on RATH`s agenda for 2024. That’s why the internationally active Austrian refractories manufacturer attaches great importance to continuous research and development. FOURATH®4 is a current example of this.
