It is formed by coating the surface of a base made of Nifine ceramics with aluminum oxide. However, even if it is formed in this way, the surface will wear out after being used for a long time (C2). If the surface wears out like this, quantitative performance will be impaired. ≦2, the function of the metering tray cannot be fulfilled.For this reason, at present, the metering tray must be replaced or recoated within a short period of time, resulting in emergency C: poor workability.

ある。The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide a method for manufacturing a fire-resistant and insulating castable that is less worn out even when used for a long time.
以下（−１この発明に係る耐火断熱キャスタゾルの製造
方法の一実施例を、溶融アルミニウム用の定量受皿の製
造方法の場合Ｃ二連用して、詳細に説明する。Below (-1) An embodiment of the method for manufacturing a fireproof and heat-insulating casta sol according to the present invention will be described in detail by using C twice in the case of a method for manufacturing a metering tray for molten aluminum.
まず、所定の枠中にダージとなるべく正確（二その容積
を規定された雄型な収納する。First, the dirge is stored in a predetermined frame as accurately as possible (second, its volume is defined in a male form).
一方、定量受皿の材料としての骨材を準備する。この骨
材は、軽石を１乃至３、シャモットを３乃至５．ホール
ステライトを２．フライアッンユを２．酸化アルミニウ

インダが準備される。On the other hand, as a binder as an adhesive, colloidal silica is used in a range of 10 to 15, and sodium acid is added in a range of 20 to 30.
Potassium earth acid in the range of 20 to 30, Sodium montmorinite (5% solution) in the range of 10 to 20,
It is formed by mixing amorphous silica in a range of 5 to 10 and water in a range of 5 to 20 so that the total of each becomes 1001. In addition, as a suitable example, colloidal silica is 13, and earth acid soda is 25. Potassium earth acid 2
5. Sodium Montmorinite (5-width liquid) 15. 7. Amorphous silica. A binder mixed with 15 parts water and 15 parts water is prepared.
１ このようにして形成された骨材と・々インダとを１
０対６の割合で混合して材料を形成し、この材料を前述

型を取り除く。1 The aggregate thus formed and the ind.
A material is formed by mixing in a ratio of 0:6, which is poured into the frame containing the male mold described above, and left until the material solidifies. After the material has solidified, remove the frame and remove the male mold.
この雄型が取り除かれた後（二残った凹所（＝、溶融ア
ルミニウムが注入され、定量されること≦；なる。After this male mold is removed, molten aluminum is injected into the two remaining recesses and quantified.
このようにして形成された定量受皿は長時間の使用の後
≦二おいても、アルミニウムとの反応もなく表面の消耗
が少なく、定量性が維持される。従って、従来のように
、所定時間使用する度に取り換たり１表面のコーティン
グをし直す必要がなく１作業性が非常に向上する。Even after a long period of use, the metering tray formed in this way does not react with aluminum, has less surface wear, and maintains quantitative performance. Therefore, there is no need to replace the coating or recoat one surface every time it is used for a predetermined period of time, as is the case in the past, and work efficiency is greatly improved.
また材料を固化させる際に加熱動作は必要でなく、製造
玉軸も非常に簡略であり、現場の作業を煩すことがない
、また、このようにして形成された定量受皿は従来のも
のと比して、耐火度及び耐反応性Ｃ二も優れ、特Ｃ二溶
融アルミニウムの定量≦二好適する。In addition, no heating operation is required when solidifying the material, and the manufacturing ball shaft is very simple, eliminating the need for on-site work.Furthermore, the metering tray formed in this way is different from conventional ones. In comparison, the fire resistance and reaction resistance C2 are also excellent, and the quantitative determination of C2 molten aluminum is preferably ≦2.
この発明は上述した一実施例の方法シ：限定されること
なくこの発明の趣旨を逸脱しない範囲で種々変形可能で
ある。The present invention is not limited to the method of the embodiment described above, and various modifications can be made without departing from the spirit of the present invention.
例えば、上述した数値は一例であって１条件等Ｃ二よっ
て変動する事は言うまでもない。For example, the above-mentioned numerical values are just examples, and it goes without saying that they vary depending on one condition, etc.
