Abstract

The results of a complex of tests of refractories for glass resistance under static and dynamic conditions and the electric resistance during glass melting are presented.

The tests of the refractories in a phosphate glass melt at 800–1100°C showed that the most stable material is the fusion-cast chromia-alumina-zirconia refractory ER-2161 with chromium oxide content 26 mass%. The pressed chromia-corundum refractory KhKT-10 possesses adequate glass resistance and is an electric insulator under the glass melting conditions in the ÉP-500 melter.

On the basis of the results of comparative tests of chromia-containing refractories and Bakor-33, the refractories ER-2161 and KhKT-10 are recommended for the masonry of future furnaces as a material for the bridgewall and the electric-insulation layer in a two-layer threshold.
