The Research And Manufacture Of V-Ti Smil-steel Roller

Smil-steel roller is made use of hot mill roll. It can be adapted to different request of rolling mill through adjusting chemical elements. We obtained V-Ti smil-steel roller through redesigning roller's chemical elements and adding to vanadium and titanium. The V-Ti smil-steel roller used the same smelting,casting,heat treatment,machining as usually smil-steel roller that its chemical elements have not vanadium and thtanium. The smil-steel roller have been made use of hot mill roll that its life is longer 10-12% and its wearable capability is good and its resisting accident faculty is well and its rigidity fall is little and its fighting back hot crack is good.So we have some conclusion that the vanadium and titanium take effect in the V-Ti smil-steel roller with separate out strengthening. It can be evidence improving roller's organizing and using.
