保定护坡模具加工厂

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。

Cement slope protection brick mold has super wear resistance: billet in mold cavity plastic deformation, along the cavity surface can flow and sliding, causes dramatic friction between the billet and the cavity surface, which leads to the failure of die wear. Therefore, the wear resistance of materials is one of the most basic and most important performance of the mold. Hardness is a major factor affecting tolerance. Under normal circumstances, the higher the hardness of cement revetment brick mold parts, the smaller the amount of wear, the better the wear resistance. In addition, the wear resistance is also related to the type, quantity, shape, size, distribution, especially 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 cement revetment brick mould: Cement revetment brick mold working conditions are very bad, the use of the site should be building region and some are often subjected to impact load, which leads to the cement slope protection brick mold brittle fracture. In order to prevent the die parts from brittle suddenly at work, the cement revetment brick mold should have higher strength and toughness. The toughness of the die depends mainly 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。

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

水泥护坡砖模具高温性能：当模具的工作温度较高进，会使硬度和强度下降，导致模具早期磨损或产生塑性变形而失效。因此，模具材料应具有较高的抗回火稳定性，以保证模具在工作温度下，具有较高的硬度和强度。

High temperature performance of cement revetment brick mold: when the mold working temperature is higher, the hardness and strength will decrease, leading to early wear of the mold or plastic deformation and failure. Therefore, the mold material should have high resistance to tempering stability, in order to ensure the mold in the working temperature, with higher hardness and strength.

水泥护坡砖模具耐冷热疲劳性能：有些模具在工作过程中处于反复加热和冷却的状态，使型腔表面受拉、压力变应力的作用，引起表面龟裂和剥落，增大摩擦力，阻碍塑性变形，降低了尺寸精度，从而导致模具失效。冷热疲劳是热作模具失效的主要形式之一，帮这类模具应具有较高的耐冷热疲劳性能。

Thermal fatigue resistance of the cement slope protection brick mold: some die in repeated heating and cooling in the working process, so that the cavity surface tension and pressure stress effect caused by cracking and spalling, increase the friction surface, hinder plastic deformation, reduce the size precision, which leads to the failure of die. Hot and cold fatigue is one of the main forms of failure of hot working dies, and this kind of mold should have higher cold and thermal fatigue resistance.

水泥护坡砖模具耐蚀性：有些模具如塑料模在工作时，由于塑料中存在氯、氟等元素，受热后分解析出HCI、HF等强侵蚀性气体，侵蚀模具型腔表面，加大其表面粗糙度，加剧磨损失

Cement slope protection brick mold corrosion resistance: some mould such as plastic mold at work, due to the presence of chlorine, fluorine plastic, after heat decomposition precipitation of HCI and HF strong corrosive gases, erosion of the mold cavity surface, increase the surface roughness, aggravate the wear loss
