凝固前沿 meaning in Chinese

solidification front
solidified front
solidifying front

The results show that temperature gradient on the front edge of solidified shell in combined mold can be reduced and the proportion of equiaxial crystal of billet is more than 80 %
结果表明：复式结晶器能够降低钢液凝固前沿的温度梯度，从而使铸坯的等轴晶率超过80 % 。
In this paper , it is proposed as a new mechanism that when a solidifying billet is in the stirring zone during continuous casting of steel , a thin steel shell is formed in front of the freezing interface , which results in a white band with a negative segregation followed by a positive one
作者提出了一个新的机制来解释白亮带的形成原因，即正在凝固的连铸钢坯位于搅拌区时，在凝固前沿形成一个薄壳，由此导致先发生负偏析，紧随其后又发生正偏析的白亮带。
