RZ15212导液盘材质为1.4408奥氏体不锈钢;质量为5.7kg,铸件上,分布锥形沉孔、沉孔、沉槽、环形沉孔、复杂的导液口和过流导液口;导液盘上分布着复杂的7个不同形状的深8mm的工艺筋;铸件为大平面结构,导液盘精密铸造工艺性较差。通过不同铸造浇注系统设计-组树工艺方案设计、浇注方式的工艺改变、在平面上通过增加工艺脐子,设计制造浇注工艺装备托架,增加型壳受力支撑,使精密铸造导液盘的成品率明显提高。
RZ15212 liquid guide plate made of 1.4408 austenitic stainless steel; mass of 5.7kg, the casting, the distribution of conical countersink, countersunk, sinking groove, ring counterbore, complex and liquid over the catheter port; liquid guide The plate is distributed with a complex of seven different shapes of deep 8mm craft tendons; castings for the large flat structure, fluid-conducting disk precision casting process is poor. Through different casting pouring system design - group tree process design, pouring process changes in the plane through the increase of technology umbilical child, design and manufacture of casting technology equipment bracket, increase the shell force support, precision casting of the liquid guide plate Yield increased significantly.
