The structure and properties of spray formed cold rolling mill work roll steels

A study of the effect of spray casting on the microstructure and properties of cold rolling mi I I work roll steels has been undertaken. Industry stan dard qualities have been spray formed and a corn parison of the resulting p roperties a nd microstructures has been made with those of the conventional ly processed counterparts. The influence of process variables on the spray formed product has also been investigated. The results indicate that cold m ill work roll steels which have comparable properties and structures to con ventionally cast and forged products can be produced successfully in a sing le processing step. Furthermore, a high integrity metallurgical bond betwee n the deposit and the substrate can be achieved. (C) 1998 Kluwer Academic P ublishers.
