SYNTHESIS OF A FRIT FOR OBTAINING ENAMEL COATING OF STEEL PIPES BY THE METHOD OF INDUCTION HEATING

Abstract

The paper presents the results of a study of the processes of glass formation during the production of a frit by the method of induction heating. According to X-ray phase analysis, the resulting frit is completely amorphous. The frit meets the standard requirements for a 45 mm flow and a thermal expansion coefficient of 120?10–7 K–1. The enamel coating has a high chemical resistance to acids and alkalis. A comparative analysis of frit synthesis in a laboratory electric furnace using an induction heating device showed that the duration of frit induction heating is halved, energy consumption is reduced by 23 %, and the process efficiency is increased four times on average.
