Within the framework of the Life5Refract project, MAGNA has participated,together with Sidenor, in the identification of potential secondary raw materials in the meltshop’s basic refractory waste. In particular, ladle demolition and tundish masses mould release materials were recovered and tested.
With this waste, MAGNA has tested 9 designs of monolithic refractory masses, using quantities of up to 70% of the recovered materials, all of which are considered technically feasible. The achievement, for the first time, of a product developed from tipped tundish waste means a real breakthrough in circular economy in steel production. The tests performed have confirmed that the new materials show features that are comparable to those of the Reference Product.
These new products were tested by SIDENOR at its BASAURI premises in new applications.
