机床铸件结构比较复杂,质量要求高。通过均衡凝固技术应用研究,采用浇注系统大孔出流理论和新的冒口类型进行工艺设计,有效地控制了铸件质量。 Machine tool casting structure is more complex, high quality requirements. Through the application research of equalization and solidification technology, the design of large-hole outflowing gating system and new riser type were used to design the process, which effectively controlled the quality of castings.
