METHOD FOR PRODUCING CHARGE Russian patent published in 2017 - IPC C03B1/02 C03C1/02 C03C6/08 

FIELD: chemistry.

SUBSTANCE: in the method of producing a charge, which includes heat treatment of the initial mixture of the source of quartz raw material and sodium hydroxide-NaOH, the mixing of the heat treatment product with the raw components, moistening and compacting, raw sources of magnesium oxide, calcium in the form of limestone, chalk, magnesite, dolomitized limestone, dolomite, technical carbonates and/or salts, calcium and magnesium halides are added to the initial mixture, and the phase composition of the heat treatment product of the initial mixture is expressed by basic amorphous and crystalline phases in the form of low-temperature β-quartz, sodium di-and metasilicates, magnesium silicates, calcium, and residual NaOH less than 5 wt %. The invention is developed in the dependent points of the formula.

EFFECT: intensifying the silicate and glass formation in the charge before charging into the furnace, reducing the maximum glass cooking temperature, shortening the clarification time and homogenization of the melt, entraining and dusting the volatile components of the glass charge, increasing the strength of the agglomerate.
