Formulation & Development of Advanced High Corrosion & Wear Resistant Material & Manufacturing Technique for Tobacco Shredding Machine Knives & Wear Parts

烟草切割机刀片（MK）是圆盘或传统的矩形形状，MK和附件是模块化结构，便于维护。烟草的研磨性/腐蚀性降低了刀片的锋利度，导致烟丝质量不均匀和机器堵塞。MK和附件必须定期更换翻新/新零件，导致机器停机时间和生产的香烟减少。传统的烟草切割MK和磨损零件由工具钢，不锈钢和低碳钢制成。切刀和辅助部件的刀具寿命很短，根据烟草的类型，刀具寿命从4小时到最长48小时不等。本研究涉及对烟草切刀市场的探索，调查MK和Ancket的制造情况。该公司希望开发一种独特的粉末冶金基材料，专门制定耐腐蚀/磨损的烟丝。这种独特的粉末金属材料将与独特的制造方法结合使用。该项目旨在评估一种新的抗烟草粉末冶金材料的配方和新的生产方法是否能提供具有先进耐磨性能的工具，同时降低整体制造成本。

Tobacco cutting machine knives (MK) are circular disk or conventional rectangular shape,MK & ancillaries are modular construction for ease of maintenance. Theabrasiveness/corrosiveness of tobacco decreases knife sharpness, causing irregularities inquality of cut tobacco & machine blockages. MK & ancillaries have to be regularly replacedwith reconditioned/new parts causing machine down times & fewer cigarettes being produced.Conventional tobacco cutting MK & wear parts are manufactured from tool steel, stainless &mild steel. The cutting knife & ancillary parts tool life are short, lasting from a little as 4 hrsto a maximum of 48 hrs depending on type of tobacco.The study involves exploration of the tobacco cutting machine market investigating themanufacture of MK & ancillaries. The company hope to develop a unique powder met basedmaterial, specifically formulated to resist corrosion/wear of cutting tobacco. This uniquepowder met material will be used in conjunction with a unique manufacturing method. Theproject aims to evaluate whether formulation of a new tobacco resistant powder met material& new proposed method of production would provide tooling with advanced wear propertieswhilst enabling reduced overall manufacturing costs.
