continuous cold rolling leaf make the surface structured,high accuracy and is conducive to materials transportation, reduce material damage. improve transportation efficiency. Second, the continuous cold rolling leaf is easy to install, will be able to enhance the efficiency of production and reduce production costs. Third, the physical and chemical surface treatment for cold-rolling leaf on the line can improve the ability of resisting rust and the quality appearance of screw conveyor. Four consecutive Cold rollingleaf have hardened by the cold surface hardness and wear resistance doubled% Outside of hardness up HB240. according to various costomers?need,we can roll any material and any size
