喇叭形气孔是采用卧式离心机铸造锡青铜时出现的一种特殊现象。 在实际生产中除因离心铸造特有的影响外,直接影响铸件凝固的因素还有合金的浇注温度、型筒温度、浇注速度、型筒转速、涂料等。实践证明,它们不仅影响气泡的内浮速度,且与逸出气体留下通道的弥合能力有关,因而形成不同类型的喇叭形气孔。 Flare holes are a special phenomenon that occurs when casting tin bronze using horizontal centrifuges. In addition to the actual production of centrifugal casting unique impact, the casting of solidification directly affect the casting temperature of the alloy casting temperature, the cylinder temperature, casting speed, drum speed, paint and so on. Practice has shown that they not only affect the bubble velocity within the float, and the escape of gas leaving the channel capacity to close the gap, resulting in different types of flared pores.
