| 六角护坡块模具具有超强的耐磨性：坯料在模具型腔中塑性变性时，沿型腔表面既流动又滑动，使型腔表面与坯料间产生剧烈的摩擦，从而导致模具因磨损而失效。所以材料的耐磨性是模具最基本、最重要的性能之一。硬度是影响耐性的主要因素。一般情况下，六角护坡块模具零件的硬度越高，磨损量越小，耐磨性也越好。另外，耐磨性还与材料中碳化物的种类、数量、形态、大小、分布尤其是密度有关。 When the mould cavity is worn violently, the mould surface will be damaged due to the friction between the die and the billet. Therefore, the wear resistance of the material is one of the most basic and important properties of the mold. Hardness is the main factor affecting the resistance. Generally speaking, the higher the hardness is, the smaller the wear loss is, and the better the wear resistance is. In addition, the wear resistance is also related to the type, quantity, morphology, size and distribution of carbides, especially the density. |
