High Performance Castable Refractories for Cupola Applications
Cupola melting is a desirable method of producing large quantities of consistent iron for high volume foundry casting operations. Minimizing downtime for these furnaces is key to optimal productivity. Erosion of refractories that are in contact with iron and slag limits the campaign duration and thus reduces the potential iron output of the cupola. These furnaces are available in a variety of configurations but operate on similar principles.
