摘要： PROBLEM TO BE SOLVED: To provide a single-shell mold with which in a lost-wax casting method, regardless of a type of a columnar crystal structure directional solidification, a single-crystal structure directional solidification or an equiaxial solidification in this method can be used.
SOLUTION: This single-shell mold is manufactured by passing through the following operations, that is; an operation for forming a contacting layer, by which sand grains are deposited on a layer by dipping into first slip containing ceramic grains and binder, and the contacting layer is dried; an operation for forming an intermediate layer, by which the sand grains are deposited on the intermediate layer by dipping into second slip containing the ceramic grains and the binder, and the above intermediate layer is dried; and a reinforcing layer forming operation for repeating until the shell mold having a prescribed thickness is obtained, by which the reinforcing layer is formed by dipping into at least third slip containing the ceramic grains and the binder, and the sand grains are deposited on the layer, are performed. The ceramic grains in the slip, contain fire-resistant oxide or non-zircon fire-resistant oxide, and especially not at all contain a zircon in any layer.

摘要翻译：要解决的问题：提供一种在失蜡铸造方法中使用的单壳模具，不管柱状晶体结构定向凝固的类型如何，单晶结构定向凝固或等轴固化方法可以使用。
解决方案：该单壳模具通过以下操作制造，即用于形成接触层的操作，通过浸入到含有第一滑动的陶瓷颗粒和粘合剂中将砂粒沉积在层上，并将接触层干燥; 用于形成中间层的操作，通过浸入到含有陶瓷颗粒和粘合剂的第二滑动剂中将砂粒沉积在中间层上，并将上述中间层干燥; 并且获得加强层形成操作，直到获得具有规定厚度的壳模具为止，通过浸入到包含陶瓷颗粒和粘合剂的至少第三片料中形成增强层，并且砂粒沉积在层，被执行。滑动中的陶瓷颗粒含有耐火氧化物或非锆石耐火氧化物，特别是在任何层中都不含锆石。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a multi-layer ceramic shell mold with which in a lost wax casting method, the occurrence of surface defect on a casting product is prevented.
SOLUTION: The multi-layer ceramic shell mold which contains a wax master pattern for part to be produced or the other similar material and at least one contact layer as the other material is manufactured by passing through the following processes, that is; a process for forming the contact layer by dipping the master pattern into a first slip containing ceramic particles and a binder formed with mullite particles; a process for depositing sand particles onto the above contact layer; and a process for drying the above contact layer.
