| Abstract: | The heat treatment process parameter for φ2 800 mm skin pass roll with Cr5 material has been researched and applied into the practical production,so that the secondary hardening skin pass roll used for cold rolling has been successfully manufactured.The inspected results show that the hardness of the roll proper has been reached to 85~88HS,and the metallurgical structure of which shall be tempered martensite+non-melted carbonide+residual austenite,and the quenched layer depth shall be more than 30 mm,all the mechanical property targets has met the design requirements. |
