Types of Refractory Materials Used in Different Parts of Heating Furnaces Heating furnaces are essential equipment in industries such as metallurgy, petroquímica, and machinery manufacturing. Operating under extreme high temperatures and harsh working conditions, these furnaces demand reliable and long-lasting refractory materials to ensure thermal insulation, mechanical strength, and operational safety. However, not all furnace areas face the same thermal and chemical stresses, which is why different zones require different types of refractories. At Rongsheng Refractory, we offer a full…

Refractory materials encompass a wide range of types and applications, and thus, can be classified through various methods. The most widely adopted classification systems are based on chemical properties and chemical-mineral composition, as they effectively reflect the material structure, composition, e desempenho. Below is a comprehensive classification of refractory materials. 1. Classification by Chemical Properties Refractory materials are typically divided into three categories based on their chemical properties: Acidic RefractoriesMainly composed of silicon dioxide (SiO₂). Typical products include silica bricks…

Glass Furnace OverviewIn the production of glass—taking float glass as an example—there are three major thermal equipment systems: the float glass melting furnace, the float glass tin bath, and the glass annealing lehr. The glass melting furnace plays a crucial role in melting the raw materials into molten glass, followed by clarification, homogenization, and cooling to the forming temperature. The tin bath is a key component for forming the glass. Molten glass at a temperature of 1050–1100°C flows through the…
