High Performance Castable Refractories for Cupola Applications
Refractory materials are used to provide protection against molten iron and slag attack particularly in the well siphon box and tap hole (Fig 1). The demand on refractories in the cupola furnace is severe. Materials must withstand thermal mechanical and chemical attack. Since cupola downtime is costly Crude steel production begins with the reduction process where the iron ore reacts with carbon sources inside the blast furnace. The blast furnace requires different types of refractory products with resistance to thermo-mechanical and thermo-chemical reactions.
