对KC蜡和K蜡的灰分、收缩和抗弯强度三种模料特性进行了对比研究。结果显示:KC蜡的灰分小于0.07%,符合公司内控标准;在自由收缩状态下,KC蜡的收缩小于K蜡,收缩可控;KC蜡的抗弯强度(9.527 MPa)大于K蜡(6.197 MPa),因而更适合制作易变形的钛合金熔模精密铸件。在上述研究的基础上,对KC蜡进行了工程化应用,首次将其应用于某大型复杂钛合金熔模精密铸件中,达到了降本增效,提高质量的效果。 KC wax and K wax ash, shrinkage and bending strength of three mold properties were compared. The results showed that the ash of KC wax was less than 0.07%, which accorded with the internal control standard of the company. The shrinkage of KC wax was less than that of K wax in shrinkage condition, and the shrinkage of KC wax was controlled. The flexural strength of KC wax (9.527 MPa) ), Which is more suitable for the production of deformable precision castings of titanium alloy investment. Based on the above research, the KC wax has been applied in engineering. For the first time, it has been applied in the casting of a large and complex titanium alloy to achieve the purpose of cost reduction and efficiency improvement and quality improvement.
