AIRTIGHT SAGGER FOR LOW-FIRED PROCESS, AND AIRTIGHT SAGGER FOR HIGH-FIRED PROCESS

摘要

PROBLEM TO BE SOLVED: To solve a problem in which an exclusive ceramic furnace is required and a large cost is needed in order to perform a nitridation process in the new ceramic field or the steel field.;SOLUTION: An airtight sagger for low-fired process and an airtight sagger for high-fired process are used. Thereby, an exclusive ceramic furnace is not needed, and it becomes possible to use an existing ceramic furnace conventionally generally used in the ceramic field and to perform a nitridation process or a carbonization process without the need of a large equipment investment.;COPYRIGHT: (C)2012,JPO&INPIT
