A glass melting furnace is the core thermal equipment used for glass melting, constructed from refractory materials. When selecting refractory materials for glass furnaces, it is essential to comprehensively consider key factors such as furnace type, application location, material degradation mechanisms, the type of glass being melted, and the nature of any accompanying pigments. The refractory materials chosen must exhibit excellent resistance to corrosion by both the molten glass and gaseous media, while also possessing a sufficiently high softening temperature under load and good thermal stability.

Core equipment in the petrochemical industry, such as ethylene cracking furnaces, hydrogen reformers, process heaters, and waste liquid incinerators, operates under extremely harsh conditions including high temperatures (1100–1350°C), strong reducing atmospheres, high-temperature carburization, chemical corrosion, and frequent thermal cycling. Refractory materials must offer excellent high-temperature stability, anti-carburization, corrosion resistance, thermal shock resistance, and thermal insulation properties. Zhengzhou Jinshan Refractory Materials provides professional and reliable refractory solutions tailored to different petrochemical units, helping customers extend equipment service life, reduce unplanned shutdowns, improve energy efficiency, and lower overall maintenance costs.
