在实际生产中,正确的开设浇冒口显得非常重要。长期以来,在铸铁件生产中,浇冒口的开设主要遵循着“定向凝固”和“同时凝固”这两个原则。上世纪80年代,魏兵教授提出的铸件均衡凝固理论对铸铁件浇冒口的开设,具有重要的指导意义。现结合生产实际,谈 In actual production, it is very important to set up the proper irrigation facilities. For a long time, in the production of iron castings, the opening of runners mainly follow the two principles of “directional solidification” and “simultaneous solidification.” 80s of last century, Professor WEI Bing proposed equilibrium casting solidification cast iron casting riser opening, with an important guiding significance. Now with the actual production, talk
