PROCEDE POUR LA FABRICATION DE CYLINDRES EN ACIER TRAITE THERMIQUEMENT ET A COUCHE FRITTEE POUR INSTALLATIONS DE COULEE CONTINUE

摘要

A roller body is made of relatively low alloyed steel and sinter-coated for protection at a temperature up to 1000 DEG C; the coating is mechanically surface finished and the assembly is normalized and tempered followed by air cooling to enhance toughness and tensile strength of the roller body.
