Centrifugal composite semi-steel and graphite steel roll and roll ring
Specification: centrifugal composite steel and graphite steel
Applications: it is mainly used in section mills, finish rolling front frames of hot-rolled strip as well as rough rolling and intermediate rolling frames for rod and wire
Product character:For graphite steel roll,its microstructure consists matrix and carbide and its carbide rate is between 1.3% to 2.6%.With different alloy element and heat treatment method,the matrix is pearlite and bainite.As we know that the Cr element can stable the carbide,V element can improve the high temperature property,Ni can strengthening matrix.Semi-steel has the character of small hardness drop,good wear resistance,good high temperature resistance and over-loading character.
