求翻译：由于与石膏模型的接触作用，进气风罩最前端（远离浇口位置的薄壁处）的合金液体的温度下降较快，在STEP约为380时，此处合金液体率先开始凝固，接着凝固过程逐渐向进气风罩的大孔部位移动。是什么意思？

As the role of contact with the plaster model, the front of the intake air hood (away from the gate at the location of thin-walled) the temperature of the liquid alloy decreased rapidly, while in STEP is about 380, where the liquid was the first alloy solidification, then solidification process grad

Because contact with the plaster models, forefront inlet Hood (away from the gate location of thin-walled) alloy liquid cools down more quickly, when the STEP is about 380, here first to solidification alloy liquid, followed by solidification process of gradually moving in to the inlet holes of the
