次に、上記構成の水平出し冶具１を用いて水平出しを行う方法について説明する。まず、図８Ａ（ａ）に示す炉体１０の底１３に、図８Ａ（ｂ）に示すようにバックサンド１５を敷設し、次に、図８Ｂ（ｃ）に示すように、炉体１０の開口１１から炉体１０内に水平出し冶具１を挿入して、押付部３をバックサンド１５に接触させる。このとき、押付部３は、バックサンド１５の凹凸のある表面の凸上に載っている。そして、図８Ｂ（ｄ）に示すように、加振部５によって押付部３を振動させながら、炉体１０の開口縁部１２のボルト穴１４に第１貫通孔２１を介してボルト６を締め込むことで、押付部３でバックサンド１５の表面の凹凸をならしながら、設置部２を炉体１０の開口縁部１２上に設置して、固定する。これにより、炉体１０の開口縁部１２上に固定具２が水平を保った状態で定位し、設置部２に平行な押付部３が水平を保った状態でバックサンド１５に押し付けられるので、図８Ｃ（ｅ）に示すように、バックサンド１５の表面が水平となる。
Next, a method for leveling using the leveling jig 1 having the above configuration will be described. First, the back sand 15 is laid as shown in FIG. 8A (b) on the bottom 13 of the furnace body 10 shown in FIG. 8A (a), and then, as shown in FIG. 8B (c), The leveling jig 1 is inserted into the furnace body 10 from the opening 11 and the pressing portion 3 is brought into contact with the back sand 15. At this time, the pressing portion 3 rests on the convex surface of the uneven surface of the back sand 15. Then, as shown in FIG. 8B (d), the bolt 6 is tightened to the bolt hole 14 of the opening edge 12 of the furnace body 10 through the first through hole 21 while the pressing unit 3 is vibrated by the vibration unit 5. As a result, the installation unit 2 is installed on the opening edge 12 of the furnace body 10 and fixed while leveling the surface of the back sand 15 with the pressing unit 3. As a result, the fixture 2 is positioned on the opening edge portion 12 of the furnace body 10 in a horizontal state, and the pressing portion 3 parallel to the installation portion 2 is pressed against the back sand 15 in a horizontal state. As shown in FIG. 8C (e), the surface of the back sand 15 becomes horizontal.
水平出し冶具１により炉体１０の底１３に敷いたバックサンド１５の表面の水平出しを行った後は、図８Ｃ（ｆ）に示すように、水平出し冶具１を炉体１０内から取り出し、そして、図８Ｄ（ｇ）に示すように、バックサンド１５上に例えば坩堝やスリーブなどの定形品１７を設置して、図８Ｄ（ｈ）に示すように、定形品１７と誘導コイル１８との間にバックサンド１６を充填する。これにより、誘導加熱炉が築炉される。
After leveling the surface of the back sand 15 laid on the bottom 13 of the furnace body 10 by the leveling jig 1, the leveling jig 1 is taken out from the furnace body 10 as shown in FIG. Then, as shown in FIG. 8D (g), a shaped product 17 such as a crucible or a sleeve is installed on the back sand 15, and as shown in FIG. 8D (h), the shaped product 17 and the induction coil 18 are separated. The back sand 16 is filled in between. Thereby, an induction heating furnace is constructed.
以上に説明した本実施形態の水平出し冶具１によれば、振動する押付部３をバックサンド１５に押し付けて押付部３でバックサンド１５の表面の凹凸をならしながら、炉体１０の開口縁部１２上に設置部２を設置するので、設置部２は炉体１０の開口縁部１２上で水平状態で定位する。その結果、設置部２に平行な押付部３も水平を保った状態でバックサンド１５の表面に押し付けられることで、押付部３によりバックサンド１５の表面を水平にすることができる。よって、バックサンド１５上に設置された定形品１７が傾くことを防止することができる。
According to the leveling jig 1 of the present embodiment described above, the opening edge of the furnace body 10 is pressed while pressing the vibrating pressing portion 3 against the back sand 15 and leveling the surface of the back sand 15 with the pressing portion 3. Since the installation part 2 is installed on the part 12, the installation part 2 is localized in a horizontal state on the opening edge 12 of the furnace body 10. As a result, the pressing portion 3 parallel to the installation portion 2 is also pressed against the surface of the back sand 15 in a horizontal state, so that the pressing portion 3 can level the surface of the back sand 15. Therefore, it is possible to prevent the fixed product 17 installed on the back sand 15 from being inclined.
加えて、水平出し作業に多大な熟練及び労働力を必要とせずに、バックサンド１５の表面を安定して精度良く水平出しすることができるので、水平出しの失敗でやり直しによる時間ロスをなくすことできるうえ、作業者に負担をかけることがない。
In addition, since the surface of the back sand 15 can be leveled stably and accurately without requiring a great deal of skill and labor for leveling work, time loss due to redoing is eliminated. In addition, it does not burden the operator.
また、設置部２に対して連結部４が垂直方向に変位可能であるので、炉体１０の底１３の深さが変動しても、押付部３をバックサンド１５に良好に押し付けることができる。
Further, since the connecting portion 4 can be displaced in the vertical direction with respect to the installation portion 2, even if the depth of the bottom 13 of the furnace body 10 fluctuates, the pressing portion 3 can be pressed well against the back sand 15. .
また、連結部４が複数の支柱（本実施形態では寸切りボルト４０）で構成され、複数の支柱（寸切りボルト４０）が押付部３の中心周りに等角度間隔で配置されているので、押付部３をバックサンド１５に均一に押し付けることができる。
Moreover, since the connection part 4 is comprised by the some support | pillar (this embodiment bolt 40), and the some support | pillar (dimension bolt 40) is arrange | positioned at equal angular intervals around the center of the pressing part 3, The pressing portion 3 can be pressed uniformly against the back sand 15.

Further, in the above-described embodiment, the connecting portion 4 is constituted by a plurality of support columns (in the present embodiment, the cutting bolt 40). However, the connecting portion 4 is not particularly limited as long as it can connect the installation portion 2 and the pressing portion 3 in parallel, and various configurations such as a cylindrical body can be used. .
また、上記実施形態では、設置部２に対して連結部４が垂直方向に変位可能に構成されているが、連結部４は設置部２に対して必ずしも垂直方向に変位可能に構成されている必要はない。
Moreover, in the said embodiment, although the connection part 4 is comprised so that a displacement in the orthogonal | vertical direction is possible with respect to the installation part 2, the connection part 4 is comprised so that it may necessarily displace to a perpendicular direction with respect to the installation part 2. FIG. There is no need.
また、上記実施形態では、炉体１０の開口縁部１２にボルト穴１４を形成し、ボルト穴１４にボルト６を締め込むことで押付部３をバックサンド１５へ押し付けてバックサンド１５を加圧している。しかし、これに限らず、水平出し冶具１を炉体１０内に挿入して、押付部３をバックサンド１５に接触させた後、水平出し冶具１のバックサンド１５への積載による荷重で押付部３がバックサンド１５に押し付けられてバックサンド１５に加圧力が働く結果、バックサンド１５の表面の凹凸がならされて、設置部２が炉体１０の開口縁部１２上に設置されるのであれば、ボルト穴１４にボルト６を締め込むことは必ずしも必要ではなく、ボルト穴１４及びボルト６を不要とすることができる。
Moreover, in the said embodiment, the bolt hole 14 is formed in the opening edge part 12 of the furnace body 10, and the pressing part 3 is pressed against the back sand 15 by tightening the bolt 6 in the bolt hole 14, and the back sand 15 is pressurized. ing. However, the present invention is not limited thereto, and after the leveling jig 1 is inserted into the furnace body 10 and the pressing portion 3 is brought into contact with the back sand 15, the pressing portion is loaded with the load caused by the loading of the leveling jig 1 onto the back sand 15. 3 is pressed against the back sand 15, and pressure is applied to the back sand 15. As a result, the surface of the back sand 15 is uneven, and the installation portion 2 is installed on the opening edge 12 of the furnace body 10. For example, it is not always necessary to tighten the bolt 6 in the bolt hole 14, and the bolt hole 14 and the bolt 6 can be omitted.
