针对大型、薄壁、复杂钛铸件容易产生浇不足、冷隔、气缩孔等缺陷及变形、裂纹等质量问题，进行工艺摸索，采取了机加工石墨型、缝隙式顶注，设计并安装标准控制块、设置阻力点、加反形量等工艺措施，一次性浇注成功了重１１０ｋｇ、外形尺寸为１０９５ｍｉｎ×８２２ｍｉｎ×７５６ｍｍ、壁厚为９ｍｍ的弯管式钛合金铸件。通过该产品的试制，为我国大型钛铸件生产积累了经验。
For large, thin-walled, complex titanium castings prone to pouring inadequate, cold, shrinkage and other defects and deformation, cracks and other quality problems, process exploration, adopted the machining of graphite type, slotting top note, design and installation of standards Control block, set the resistance point, plus the amount of anti-shape and other technical measures, a one-time successful casting weight 110kg, dimensions of 1095min × 822min × 756mm, wall thickness of 9mm elbow titanium alloy castings. Through the trial production of the product, our country has accumulated experience in the production of large titanium castings.
