Study on Ware Resistance of Laser Hardening Rolling Mill Liner
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 2.7times as that of the substrate respectively; which can reached the technical requirements liner needed.
