Detail

Fine grain graphite composite centrifugal roll the working layer shape, size, distribution of graphite and carbide can be controlled by the cooling and alloy content, due to the addition of manganese,chromium, nickel, molybdenum and other alloy elements, the matrix structure can change frompearlite, bainite to martensite, exist with a small amount of fine graphite, not only improve the rollspalling, thermal crack and wear resistance, and the working layer of roll barrel hardness drop is very small.
