High-Zirconia Fused Cast Refractory Applications in CTV Panel Glass Melters

摘要

The judicious application of HZFC in the sidewalls and the bottom in the forward portion of a TV panel glass melter, replacing fused AZS, will result in a significantly lower level of glass defects of refractory origin. Laboratory studies of refractory corrosion as well as modeling, when coupled with early observations of industrial furnaces, suggest that HZFC will corrode more than fused AZS, especially below the glass line. This has led to further studies regarding the application of effective cooling practices. Next will come procedures for properly applying HZFC overcoat tiles to the HZFC sidewalls. All of this is done in the name of improved glass quality and improved selections of glass products from these very specialized, high-quality glass melters.
