内冷铁技术的改进与创新 The cold iron technology improvement and innovation 对内冷铁方案作了改进,将内冷铁替换为用制壳耐火材料制成的成形堵头,其尺寸完全按照内冷铁的尺寸复制,冷铁座的尺寸及制作步骤不变。堵头需事先开出专用模具打制相应堵头蜡模,一个叶轮模组需配备一个堵头蜡模,制壳时堵头蜡模只需对其内腔进行沾浆撒砂,脱蜡后即形成相应的堵头壳型,此成型堵头壳型需事先焙烧充分并冷却至室温下备用,浇注前在堵头壳型定位端圆周及配合面处涂上一层胶合剂,然后迅速插入冷型壳并压合紧密,图9为成形堵头嵌入示意图。此冷型壳可以起到类似内冷铁的冷却效果,既解决了轮毂中孔缩松缺陷,又可以减小加工工作量,降低叶轮加工成本。 Improve internal cold iron were made, cold iron replacement for use inside the shell making forming plug made of refractory material, its size according to the size of the cold iron inside completely copy, cold iron block size and production steps are the same. Corresponding plug the plug should be prior to prescribe special die forge wax models, an impeller modules need to be equipped with a plug wax models, when the shell making plug wax models simply to moistening slurry sanding inside cavity after dewaxing to form the corresponding plug shell mold, the plug molding shell mold roasting sufficient and cool to room temperature under standby, before pouring in the plug shell mold positioning the circumference of a circle and mating surface coated with a layer of cement, and then quickly inserted type cold shell and pressing close together, figure 9 for forming plug embedded diagram. In this cold shell can have similar cold iron cooling effect, solved the wheel hub hole shrinkage defects in both can reduce the processing workload, reduce the impeller machining cost.
