    模具钢材韧性值能够标准化吗?

    来源:https://www.jnqhmj.com/ 日期:2021-04-27 发布人:admin


    模具钢材韧性值能够标准化吗?现如今,随着制造业和冶炼工业不断的发展,模具钢材的应用变得越来越广泛了。
    Can toughness value of die steel be standardized? Nowadays, with the continuous development of manufacturing and smelting industry, the application of die steel has become more and more widely.
    相信不久的将来,关于模具钢材的标准韧性值以及各种材料在主要环境下的韧性参考值出现在我国的推荐性国家标准或模具行业标准中。那么,模具钢材韧性值能够标准化吗?
    It is believed that in the near future, the standard toughness values of die steel and the toughness reference values of various materials in the main environment will appear in China's recommended national standards or die industry standards. So, can the toughness value of die steel be standardized?
    在工作过程中,各种模具承受着不同的冲击载荷,为了减少在使用过程中的出现折断、崩刃等形式的损坏的频率,就需要模具钢材具有一定的韧性。
    In the working process, all kinds of molds bear different impact loads. In order to reduce the frequency of fracture, blade collapse and other forms of damage in the process of use, mold steel needs to have a certain toughness.
    韧性这个字眼在模具从业人员的嘴边常常挂起,所以它也是模材提供者比较注意的问题,模具钢的化学成分、晶粒度、纯净度、碳化物和夹杂物等的数量、形貌、尺寸大小及分布情况,以及模具钢的热处理制度和热处理后得到的金相组织等因素都对钢的韧性带来很大的影响,尤其是钢的纯净度和热加工变形情况对于其横向韧性的影响更为明显。
    Toughness is often mentioned by die and mold practitioners, so it is also a problem that die and mold material providers pay more attention to. The quantity, morphology, size and distribution of chemical composition, grain size, purity, carbide and inclusion of die and mold steel, As well as the heat treatment system and metallographic structure of die steel after heat treatment have great influence on the toughness of the steel, especially the influence of steel purity and hot working deformation on its transverse toughness is more obvious.
    特别强调钢的韧性、强度和耐磨性往往是相互矛盾的,要合理地选择钢的化学成分并且采用合理的精炼、热加工和热处理工艺,以使模具材料的耐磨性、强度和韧性达到的配合。
    It is especially emphasized that the toughness, strength and wear resistance of steel are often contradictory. It is necessary to reasonably select the chemical composition of steel and adopt reasonable refining, heat processing and heat treatment process, so that the wear resistance, strength and toughness of die material can match each other.
