摘要
对研制的钛合金精铸用蜡模料进行了分析比较 ,发现 C86 4蜡模料综合性能较好 ,其抗弯强度 14 .10 MPa,线收缩率 0 .4 0 % ,流动性 4 8.2 mm,针入度 2 10 -1mm,灰分小于0 .0 5 % ,并用其成功压制出飞机腹鳍前接头的蜡模及其钛合金精铸件 .该铸件长 6 0 0 mm,80 %的壁厚为 2 .5 mm,结构复杂 .充分证明了 C86
In this paper, the properties of developed waxs are compared. The comprehensive property of C864\|wax is better, and its flexural strength is 14.10 MPa, its line reduction 0\^4%, its flowability 48\^2 mm, its penetration 2 10\+\{-1\} mm, its ash constituent less than 0\^05%. The plane fin's front junction wax pattern and its titanium casting have been successfully manufactured. This casting is very complicated, 600 mm long and 80% of the cas\| ting is 2 5 mm thick. It is proved that C864 is very suitable to large complicated integrated thin wall titanium investment casting.
