| Abstract: | Microstructure of
matrix of low carbon high chrome casting iron is austenite and a little of martensite,the carbides
are mainly M7C3 type and a little of M23C6 type,under the casting condition b is 500600MPa and
ak is 1020J/cm2,hardness is HRC 5060.The experiment proves that the low carbon high chrome
casting iron complex roller has high service life,good wearability,high strength and this roller is
suitable to cold rolling mill and hot rolling mill. |
