Cupola bricks are a type of specialized refractory bricks designed specifically for use in cupola furnaces. Cupola furnaces are used in foundries to melt iron and other metals for casting purposes. These bricks are engineered to withstand the extreme temperatures, chemical reactions, and mechanical stresses that occur within the cupola furnace during the metal melting process.

Cupola bricks are made from high-quality refractory materials that can endure the intense heat generated by the combustion of coke or other fuels used to melt the metal. They are carefully designed to resist erosion, thermal shock, and the corrosive effects of molten metal and slag. These bricks are shaped and sized to fit the lining of the cupola furnace, creating a protective barrier that ensures efficient heat transfer and containment while maintaining structural stability.

Due to their critical role in the metal melting process, cupola bricks are a crucial component in achieving consistent and reliable performance in cupola furnaces, ultimately contributing to the production of high-quality castings.
