[0027] Laser Surface Hardening of Infinitely Chilled Cast Iron Rolls
[0028] First, take the infinite chilled roll used for rolling seamless steel pipe as the processing object, the central arc radius R=71.74mm, according to figure 1 The display is divided into 7 areas, of which the arc of area I is 10 degrees, the arc of area II is 20 degrees, the arc of area III is 35 degrees, the arc of area IV is 50 degrees, the arc of area V is 35 degrees, the arc of area VI is 20 degrees, and the arc of area VII is 10 degrees .
[0029] Secondly, install the roll to be treated on the workbench, use sandpaper or hand-held grinding wheel to derust the working surface of the roll, and clean the working surface of the roll with acetone until the surface is smooth and free of oil; The light-absorbing paint is evenly sprayed on the surface of the roll, and the thickness of the sprayed layer of the light-absorbing paint is about 0.05mm.
[0030] Then, the surface of the roll is laser hardene...
