雨淋浇口是一种可靠、实用的浇注系统,它有如下特点: 1.铁水呈多股细流平稳充型,阻力小、冲击力弱,能促使液面活跃,除渣及排气效率良好。 2.使铸件有合理的温度场,能避免局部过热,有利于均衡凝固,补缩作用强。浇得铸件材质致密、均匀,铸造应力小。 3.结构简、形式多、便操作、易清理。 4.不仅能用于套筒和轮类铸件,还能用于平饭、实条、箱体等多类铸件,适应范围广。雨浇淋口具备上述特点,必须掌握正确的设计方法,即合理地选择结构型式和恰当地计算浇口截面。
Rain shower is a reliable and practical pouring system, which has the following features: 1. The molten iron is stably filled with multiple strands, the resistance is small and the impact is weak, which can promote the active level of liquid, slag removal and exhaust efficiency good. 2. The casting has a reasonable temperature field, to avoid local overheating, is conducive to balanced coagulation, the role of strong shrinkage. Casting cast material is dense, uniform, casting stress is small. 3. Simple structure, many forms, they operate, easy to clean. 4. Not only for the sleeve and wheel castings, but also for flat meals, real bars, boxes and other types of castings, to adapt to a wide range. Rain pouring with these characteristics, we must master the correct design method, that is, a reasonable choice of structural type and the proper calculation of the gate section.
