contraction of solidification

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.
利用球墨鑄鉄凝固過程中的石墨化膨脹，進行自身補縮，可以實現少胃口或無冒口鑄造。
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.
實際工作中，我們可以應用這個表達式來定量求出放熱麪積，對樹脂固化的最終強度、硬度、收縮等遠期性能作超前的定量的比較。
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.
最後分別討論了鋼種、結晶器長度、拉坯速度、鑄坯斷麪尺寸與結晶器錐度、凝固收縮系數的關系。
