Paper Title:
Study on Ware Resistance of Laser Hardening Rolling Mill Liner
  Abstract

In order to change the traditional status that rolling mill liner can not be manufactured with a single material, laser transformation hardening was carried out by HL-1500 cross-flow CO2 laser processing machine on 45 steel surface. developed a non-composite liner instead of the original. The microstructure and properties were researched by means of scanning electron microscopy, X-ray diffractometer, microhardness tester and abrasive wear testing machine. The result indicate that, the microstructure of laser transformation hardening layer fine and homogeneous, mainly composed of Fe, Fe3C, Fe-Cr and Cr3C2, the hardness and the relative wear resistance are about 3 times and 2.7 times as that of the substrate respectively; which can reached the technical requirements liner needed.
