            熱作模具鋼的壽命體現在哪些方面?

            一些工程的具體規劃還是需要根據需求而定的,比如說一些模具的選擇和應用要看具體的情況而定。那么熱作模具鋼使用壽命是多久,了解這些內容以后對于選購熱作模具鋼這個問題會有很好的參考作用和價值,下面就對于熱作模具鋼這個問題進一步的了解和分析。
            The specific planning of some projects still needs to be determined according to the needs, for example, the selection and application of some molds depends on the specific situation. So how long is the service life of hot working die steel? After understanding these contents, it will have a good reference and value for the purchase of hot working die steel. The following is a further understanding and analysis of the problem of hot working die steel.
            定模具使用壽命重要的因素往往是模具材料的耐磨性。模具在工作中承受相當大的壓應力和摩擦力,要求模具能夠在強烈摩擦下仍保持其尺寸精度。模具的磨損主要是機械磨損、氧化磨損和熔融磨損三種類型。
            The wear resistance of die material is often an important factor to determine the service life of die. The die bears considerable compressive stress and friction in work, so it is required that the die can maintain its dimensional accuracy under strong friction. There are three main types of wear: mechanical wear, oxidation wear and melt wear.
            為了改善模具鋼的耐磨性,就要既保持模具鋼具有高的硬度,又要保證鋼中碳化物或其他硬化相的組成、形貌和分布比較合理。
            In order to improve the wear resistance of die steel, it is necessary to keep the die steel with high hardness and ensure the reasonable composition, morphology and distribution of carbides or other hardening phases in the steel.
            對于重載、高速磨損條件下服役的模具,要求模具鋼表面能形成薄而致密粘附性好的氧化膜,保持潤滑作用,減少模具和工件之間產生粘咬、焊合等熔融磨損,又能減少模具表面進行氧化造成氧化磨損。所以模具的工作條件對鋼的磨損有較大的影響。
            For the die in service under heavy load and high speed wear condition, it is required that thin and dense oxide film with good adhesion can be formed on the surface of die steel to maintain lubrication, reduce melting wear such as sticking and welding between die and workpiece, and reduce oxidation wear on die surface. Therefore, the working conditions of the die have a great influence on the wear of the steel.
