The experiment study about the subcritical normalizing holding temperature effects the macrostructure and hardness of the 40SiMnCrNiMoA steel shows: When subcritical normalizing holding temperature is 760℃, the ferrite in the mixture phase structure is lumpish, the hardness of the steel is low (about HRC32), and when the holding temperature is over 800℃, the hardness of the steel is about HRC49, the ferrite in the mixture phase structure is in old critical range austenite grain boundaries, it is disadvantage for the steel strengthening. When the holding temperature is 780℃, the mixture phase structure is mixture phase structure including the strip ferrite、martensite and bainite, the ferrite is less than 20%wt, its grains are fine and even, the hardness of the steel is about HRC38, it is in the range of HRC35-40 which is the long-life drill rod needed.

通过对Wisterch参数，钢丝与模具接触长度、定径带长度、工作锥角度的研究得到了在不同拉拨条件下模芯采用的最佳几何尺寸，并研究最佳工作锥角、定径带长度下钢丝在模具中的发热量、空气中散热量、卷筒上的散热量及其模具散热量的不同，导致钢丝进出模具的温度差别对钢丝机械性能的影响，在实验中根据同种拉拨条件下采用不同工作锥角半角、定径带长度进行试验，得出结论，工作锥角越大则钢丝与模具接触长度越短，钢丝变形越剧烈，在模具中发热量就越高，导致钢丝出模温度高，使钢丝强度、硬度升高，弯曲、扭转次数降低，并且降低模具使用寿命。在其它条件相同的情况下，定径带越长则钢丝与定径带简壁磨擦增大，使钢丝发热量加大，从而使钢丝强度、硬度略升高，弯曲扭转次数略降低但定径带的增大减小了钢丝变形产生的弹性后效使钢丝出模直径比较稳定。
