水泥护坡砖模具材质特征

Material characteristics of cement slope brick mold

水泥护坡砖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，水泥护坡砖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。

The mould of the cement revetment brick has super wear resistance: when the blank changes in plastic mold cavity, it moves and slides along the surface of the cavity, resulting in severe friction between the surface and the billet, resulting in failure of the die due to wear. 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 tolerance. In general, the higher the hardness of the mould parts, the smaller the wear and the better the wear resistance. In addition, the wear resistance is also related to the type, quantity, shape, size, distribution and density of carbides in the material.

水泥护坡砖模具强韧性：水泥护坡砖模具的工作条件大多十分恶劣，使用地点应建筑地域而定，有些常承受较大的冲击负荷，从而导致水泥护坡砖模具脆性断裂。为防止模具零件在工作时突然脆断，水泥护坡砖模具要具有较高的强度和韧性。模具的韧性主要取决于材料的含碳量、晶粒度及组织状态。

The strength and toughness of mould for cement revetment brick: the working conditions of cement slope protection bricks are mostly very bad. The location should be decided by building area. Some of them often bear large impact load, resulting in brittle fracture of cement revetment brick mold. In order to prevent the sudden brittle fracture of the mold parts at work, the cement slope brick mould should have high strength and toughness. The toughness of the mold mainly depends on the carbon content, grain size and microstructure of the material.

水泥护坡砖模具疲劳断裂性能：模具工作过程中，在循环应力的长期作用下，往往导致疲劳断裂。其形式有小能量多次冲击疲劳断裂、拉伸疲劳断裂接触疲劳断裂及弯曲疲劳断裂。模具的疲劳断裂性能主要取决于其强度、韧性、硬度、以及材料中夹杂物的含量。

The fatigue fracture performance of the cement slope brick die: in the working process of the mould, the fatigue fracture is often caused by the long-term action of cyclic stress. Its form has small energy multiple impact fatigue fracture, tensile fatigue fracture contact fatigue fracture and bending fatigue fracture. The fatigue and fracture properties of the mold mainly depend on its strength, toughness, hardness, and the content of inclusions in the material.
