METHOD OF MELTING GLASS IN SKULL CRUCIBLES Russian patent published in 2023 - IPC C03B5/08 

FIELD: production of silicate glasses.

SUBSTANCE: invention can be used in the glass industry. The technical result of the proposed method is to accelerate the process of glass synthesis. The method for melting glass in skull crucibles includes creating a skull in the crucible, making up a charge and loading it into the crucible, melting glass, casting the melt into metal moulds, and annealing in a muffle furnace. Creation of the skull is carried out in a crucible of high-alumina refractory by melting the surface with a plasma jet for 1-2 minutes at a temperature of 6000-8000 K. After that, the charge is loaded into a crucible of high-alumina refractory with a skull layer, which is melted using a plasma jet, and then cooking is carried out glass for 5-6 minutes.

EFFECT: accelerated process of glass synthesis
