PROPERTIES
Thanks to its high content of M7C3, type carbide in range of 20-30% and discontinuous network distribution of carbide, the roll offers a high wear resistance performance. The matrix is finely-disseminated secondary carbides (M7C3,M23C5 and M3C types), increasing therefore the wear resistance of roll, The Cr2O3 enriched oxide film on the roll surfaces is highly resistant to oxidization and plastic strain, making the roll extremely suitable for steel hot milling process. | ||||||||||||

High-speed Steel Roll
High-speed steel roll has high hardness and abrasive resistance under high
temperature. It is made by centrifuge method; the core part is made of nodular cast iron. Through component and heat treatment technique, the hardness in working layer is able to reach 80-85HSC; matrix in martensite contains V, W, Mo
compound carbide so as to assure the even hardness and aperture abrasion in working layer. This kind of roller is applicable to finishing rack to expand working period and improve surface quality of rolling materials.

GNV Roll
Roll for rough milling rack needs to be combined with certain characteristics, among of which, some characteristics will be cancelled out by the opposite side, including abrasive resistance, thermal cracking resistance, shock resistance, thermal hardness, thermal strength, etc. Excessive net carbide is able to improve the abrasive resistance, shock resistance which then lower the fracture toughness which then will result in production of thermal cracking under rough milling situations. Therefore, in order to reduce the influence of excessive carbide but also maintain the abrasive resistance, Ni and Mo must be added to let the matrix under bainite/ martensite (acicular) which is more wearable then ordinary matrix in pearlite. The Mo element is also good to improve harness of roll under high temperature.
GNV Roll is made of high alloy materials through special heat treatment, the
content of carbide in the matrix is lower than 5% so as to meet requirement from rough rolling rack.
