数值模拟结果表明：升温速率和对流换热系数通过改变峰值温度影响回弹角，固化压力通过改变树脂分布和含量影响回弹角；铺层方向引起的结构力学性能的变化是回弹角差异较大的主要原因，厚度对固化变形的影响需考虑其对峰值温度和结构刚度变化两方面因素的综合影响，拐角半径的变化对固化变形的影响较小；模具形式通过改变树脂分布梯度和模具对结构的作用力位置影响回弹角，模具材料和形式的选择对于固化变形控制具有重要意义。
Owing to facing a great deal of problems in the course of manufacturing metal functional exemplars by combining SLA rapid prototypes, SLS rapid prototypes and precision casting process, a great deal of experiments (included inmeasurement of prototypes residual ash content, measurement of contact angle between prototype and binder, testing of coating thickness on prototypes, testing of gas evolution of mold flour after roasting prototypes in mould) are made. By these technical parameters we can draw a conclusion that there are some special problems when the prototypes made of resin, plastic, or wax can be directly used in making metal functional exemplars through Shaw process or precision investment casting process.

Results show that higher casting speed leads to higher face temperature and thinner shell thickness of the slab at exit of the mold.

沿宽面从液面向下凝固壳厚度逐渐增加，生长速度加快；沿窄面从液面向下，除了流股冲击的区域凝固壳减小外，凝固壳厚度也逐渐增加；在高拉速下，结晶器出口坯壳表面温度增加，坯壳厚度减小；浇注温度过热度较高时，出口坯壳厚度也减小；较深的水口插入深度使得结晶器内高温区下移，出口坯壳也减小。
In comparison with bugle shaped nozzle, bifurcated nozzle downward jet angle 45°, cow-nose nozzle and three-hole nozzle, in all, the last two are better than the former and bifurcated nozzle downward jet angle 45 is better than bugle shaped nozzle; Cow-nose nozzle is helpful for guaranteeing the product's quality, in order to protect jet flow from eroding the strand at narrow face, gain uniform temperature distribution at cross section and decrease heat flux, adding the block's width to 100 mm. Three-hole nozzle is advantageous to increase flux and casting speed, but should avoid weak shell thickness in the center broad. In the real production, setting the SEN's immersed depth or plugging the hole at the bottom can adjust the flow and temperature distribution in the mold.
对比喇叭形水口，双侧孔水口(45°)，牛鼻子水口和三孔水口，总的说来后两者优于前两者；而双侧孔水口(45°)又优于喇叭形水口；牛鼻子水口和三孔水口比较各有特点，前者对保证铸坯质量有利，为防止流股对窄面的冲击，增加挡块宽度到100 mm，可使结晶器横截面上温度分布更加均匀，降低窄面热负荷；后者对增加流量，提高拉速非常有利，但要防止中孔射流过强导致铸坯中心坯壳变薄，在实际生产中可通过控制水口浸入深度或塞住浸入式水口的底孔来调节结晶器中的流动与温度分布状态。

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。
