The spiral leaf blade cold-rolling mill is with  the continualrolling leaf blade's advanced equipment, it through the adjustmentspot (roller displacement, feeds into highly,  pressure,guidance turn and so on) adjustment, may the rolling leave each kindof specification leaf blade which needs. At present the domesticmanufacture leaf blade's method includes: The single unit rammingwelding forming, the extrusion forming, twines method and so onforming, cold rolling forming. Cold rolling forming method, has theproduction efficiency high, the economical raw material, the leafblade quality good, degree of hardness high, the resistance to wear isgood and so on the merit. The influence rolling forming factor, has the material quality and thickness, the roller displacementquantity size, feeds into highly, the roller grinds the pressure, theguidance wheel, leaf blade's specification is different as well as inthe rolling process, the roller temperature rises the higher manyfactors. The our company passes through in recent years unremittingendeavor, a forming, the continual cold rolling spiral leaf bladewhich the development develops has the surface smoothly,wear-resisting is durable, does not need to weld and so on manymerits, selects the import steel belt rolling, widely uses inprofession and so on in farm machinery, grain, food, chemicalindustry, medicine, mining, the transportation, the mix, stirs,bulldozes, rubs rubs and so on the use
