Abstract

The technological aspects of producing frit based are studied for heat-resistant enamel EV-300-60M in experimental industrial conditions. It was found that in the temperature range of 1200–1250 °C, intensive foaming of the charge occurs due to the active release of oxygen by manganese oxide. Due to the combination of technological operations, it is possible to ensure a sufficient reduction, but not complete exclusion of foaming when cooking frit. In this regard, the further direction of work on improving heat-resistant enamels for the protection of corrosion-resistant steels determines the need to develop a technological composition of frit.
