solidification contraction

基本解释

The self-compensated contraction caused by graphite dilatation in the solidification process of nodular cast iron makes casting with less flow-off or casting without flow-off possible.
利用球墨铸铁凝固过程中的石墨化膨胀，进行自身补缩，可以实现少胃口或无冒口铸造。
In our practical work, we can apply it to quantify exothermic area. And we can also apply it to compare quantitatively the last intensity, hardness and contraction of resin solidification.
实际工作中，我们可以应用这个表达式来定量求出放热面积，对树脂固化的最终强度、硬度、收缩等远期性能作超前的定量的比较。
In the end the relationship of steel grades, mould length, drawing speed and sectional dimensions of the billet with mould taper and solidification and contraction coefficient has been discussed.
最后分别讨论了钢种、结晶器长度、拉坯速度、铸坯断面尺寸与结晶器锥度、凝固收缩系数的关系。
