SGT - 20th Furnace Solutions
The Society of Glass Technology (SGT) will host its 20th Furnace Solutions Conference in St Helens, UK on 3-4 June 2026, bringing together glassmakers, end users, and suppliers around the realities of decarbonisation.
Abstract: Soldier block corrosion profile simulation, a tool to understand the impact of low carbon melting process evolution
As future of Glass industry is intensively related to energy consumption decrease and low carbon emission, new trends in glass melting technologies are happening. This could have a significant impact on the corrosion of glass contact refractory blocks.
For these reasons, SEPFRO has developed since few years finite element model to simulate corrosion soldier block profile. Based on the understanding of corrosion laws and the physical properties of Electrofused Cast materials and coupled with CFD data, that gives glass temperature profile and glass velocity profile at the vicinity of refractory interface, we can estimate corrosion profile evolution of soldier block with time.
We will discuss and compare the different corrosion profile that could be obtain with different melting technology and melting conditions. Starting with flame furnace as reference, we will observe corrosion profile evolution when going to hybrid furnace and full electric furnace on generic cases.
The model helps also to analyze the impact of different parameter such as refractory material properties, refractory thickness, cooling efficiency and others. Moreover, we will disclose different model development that could take in account more complex corrosion situation such as throat, barrier wall and bottom
