solidification contraction

基本解釋

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(jìn)行自身補(bǔ)縮，可以實現(xiàn)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(yīng)用這個表達(dá)式來定量求出放熱麪積，對樹脂固化的最終強(qiáng)度、硬度、收縮等遠(yuǎn)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(jié)晶器長度、拉坯速度、鑄坯斷麪尺寸與結(jié)晶器錐度、凝固收縮系數(shù)的關(guān)系。
