      现在威尼斯城所有登入网址普遍适用,那么大家知道威尼斯城所有登入网址具有哪些功能特性吗?以及注意的问题:威尼斯城所有登入网址具有较低的热锻变形抗力,塑性好,锻造温度范围宽,锻裂冷裂及析出网状碳化物倾向低;切削用量大,刀具损耗低,加工表面粗糙度低;威尼斯城所有登入网址高温加热时抗氧化性能好,脱碳速度慢,对加热介质不敏感,产生麻点倾向小;威尼斯城所有登入网址淬火后具有均匀而高的表面硬度;淬火后能获得较深的淬硬层,采用缓和的淬火介质就能淬硬;威尼斯城所有登入网址淬火变形开裂倾向常规淬火体积变化小,形状翘曲、畸变轻微,异常变形倾向低。常规淬火开裂敏感性低,对淬火温度及工件形状不敏感;威尼斯城所有登入网址砂轮相对损耗小,无烧伤极限磨削用量大,对砂轮质量及冷却条件不敏感,不易发生磨伤及磨削裂纹。

             

      Now the slope protection die is generally applicable. Do you know what functional characteristics of the slope protection mold are? As well as the problems to be paid attention to: the slope mould has low deformation resistance of hot forging, good plasticity, wide forging temperature range, low forging and cold cracking and low precipitation of reticulated carbide, low cutting consumption, low cutting tool loss and low surface roughness, good oxidation resistance and slow decarburization of slope mould at high temperature. The quality is not sensitive, and the pitting tendency is small; the slope mould has a uniform and high surface hardness after quenching; after quenching, it can get a deeper hardened layer and harden with a mild quenching medium; the tendency of quenching and cracking of slope protection die tends to be small, the shape warp, the distortion is slight, and the abnormal deformation tendency is low. The cracking sensitivity of conventional quenching is low, and it is insensitive to the quenching temperature and the shape of the workpiece; the relative loss of the grinding wheel of the slope protection mould is small, the consumption of the burn limit grinding is large, the quality of the grinding wheel and the cooling condition are not sensitive, and the grinding and grinding cracks are not easy to occur.
