摘要

对某厚大实心双联叶片晶粒度超差、铸件叶型鼓胀及尺寸超差、缘板缩松等问题进行分析

通过降低浇注温度、采用复合型壳、陶瓷棉包裹及优化蜡模压制参数和防变形工艺条、应用制壳工艺筋和局部型壳增强等措施

解决了上述问题。

Abstract

The problems in crystal grain defect

airfoil swelling and over size as well as platform porosity were described. These problems were resolved effectively by decreasing pouring temperature

adoting composite ceramic shell

wrapping aluminium silicate fiber as well as optimizing wax and shell making parameters

using anti-deformation processing rib

shell making rib and partial enhancing shell.
