Fire-resistant gray castings

Common gray casting has been widely used due to its low price. Nevertheless, it is not resistant to increased thermal loadings. Therefore, the components such as furnace and boiler burners, which are exposed to prolonged stresses, are maid out of fire-resistant gray castings. Nowadays we have different kinds of fire-resistant gray castings broadly used (depending on alloy elements). This paper studies the influence of silicon on fire-resistant properties, and presents results of investigation of fire-resistant gray casting under operational conditions.
