Iron oxides effect on glass kilns performance and gloat-glass product quality

It is noted that maintaining within a given level of the content of iron oxides in glass and the optimal ratio between oxides of ferrous and ferric iron increases the efficiency of glass furnaces. More stringent requirements for the quality of raw materials for the production of float glass have been formulated. The magnitude of fluctuations of iron oxides in the raw material and its influence on the stability of the melting and glass production process have been revealed and analyzed. The technique of introducing an iron-containing component (crocus) into the charge to smooth out sharp fluctuations of iron oxides in the raw material is described. The relationship between changes in the temperature of the gas space, molten glass in the furnace and the total consumption of gas fuel with the nature of changes in the amount of FeO and Fe ₂ O ₃ is indicated.
