Metalcasting Industry Roadmap Furnace Refractories


This refers to the heat-resistant materials that constitute the linings for the furnaces and ladles used in metalcasting. In addition to being resistant


to thermal stress and other physical


phenomena induced by heat, refractories must also withstand physical wear and corrosion. The R&D needed in this area includes improvements in new materials to improve quality / reliability, costs, and energy efficiency.


a. Improve Furnace Refractories ± Improved furnace refractories are needed to improve the performance of furnace refractories. This includes improved insulating effects / resistance to heat, better non-wetting properties, and longer performance life / reduction of refractory material deterioration over time and usage. Failure of refractory material may result in the loss of production time, equipment, and even the casting itself.


Key Tasks


x Baseline existing refractories x Develop testing techniques x Test new refractories in-plant


Target Outcomes


x Higher quality cast parts x Reduced porosity x Reduced gas related defects x Improved surface finish x Improved dimensional repeatability x Elimination of veining and erosion defects x Less scrap and re-work x Energy reduction / improved energy efficiency
