IMPREGNATION CRUCIBLE
To provide an impregnation crucible which has improved use life.SOLUTION: A method for manufacturing an impregnation crucible includes: a depressurization step (A) of putting a reduced and fired crucible material 10 into an empty impregnation tank 11 and depressurizing inside of the impregnation tank 11; a filling step (B) of filling the depressurized impregnation tank 11 with a solution 12 of an erosion resistant component through a conduit 14 from a solution tank 13; a pressurization step (C) of pressurizing the inside of the impregnation tank 11 filled with the solution 12 of the erosion resistant component, and impregnating a pore of the crucible material 10 with the erosion resistant component; and an opening step (D) of impregnating the pore with the erosion resistant component in the impregnation tank 11 and then opening the impregnation tank 11 to the air, and simultaneously returns the solution 12 of the erosion resistant component to the solution tank 13 through the conduit 14 from the impregnation tank 11 and takes out the crucible material 10 from the impregnation tank 11.SELECTED DRAWING: Figure 1
【課題】使用寿命の向上を図った含浸坩堝を提供すること。【解決手段】含浸坩堝の製造工程は、空の含浸槽11に還元焼成した坩堝材料10を入れて含浸槽11の内部を減圧する減圧工程(A)と、減圧した含浸槽11に溶液タンク13から管路14を通して耐溶損成分の溶液12を充填する充填工程(B)と、耐溶損成分の溶液12を充填した含浸槽11の内部を加圧して坩堝材料10の気孔中に耐溶損成分を含浸させる加圧工程(C)と、含浸槽11で気孔中に耐溶損成分を含浸させた後、含浸槽11を大気に開放するとともに、含浸槽11から管路14を通して耐溶損成分の溶液12を溶液タンク13に戻し、含浸槽11から坩堝材料10を取り出す開放工程(D)を備える。【選択図】図1
