结构如图所示的薄壁端封板铸件,它是纺织机械产品上的大型铸件之一。其重重540kg,长3000mm、宽1440mm、主要壁厚12mm;材质HT150,采用手工造型湿型铸造;浇注铁水来自3t/h两排风口冲天炉。该件生产中出现的问题是易产生变形,即铸件中间部位翘曲7～10mm。针对这一问题,该厂采用开放式的浇注系统、单向浇口、倾斜浇注,并适当提高浇注温度和浇注速度,也采取了一些辅助措施,解决了铸件变形。浇注系统:浇注系统布置在铸件薄壁一边;
Structure Thin-walled end-seal castings as shown, one of the largest castings on textile machinery. The weight of 540kg, length 3000mm, width 1440mm, the main wall thickness of 12mm; material HT150, the use of hand-shaped wet casting; pouring hot metal from 3t / h two-row outlet Cupola. The production problems in the production is easy to produce deformation, that is, the middle part of the casting warpage 7 ~ 10mm. In response to this problem, the plant uses an open casting system, one-way gate, tilt casting, and appropriate increase in pouring temperature and pouring speed, but also taken some auxiliary measures to solve the casting deformation. Casting system: Casting system is arranged on the thin-walled casting side;
