従来、 ガラス溶融炉の電極素材と して用いられるガラス溶融 炉用電極材料と しては、 例えば、 C uを： 1 0〜 6 0 B aを 0.5 〜 5 %含む M o基合金 （特開昭 49-88739号公報） や、 R h を 1 〜 2 0 %， Wを 0.5 〜 5 %含む卩 t 基合金 （特開昭 53- 51124 号公報） などがあり、 そのほか、 酸化錫を用いたものや N i基合金を用いたものなどもあった。 そして、 N i基合金と しては、 C rを約 3 0 %、 ？ 6を約 9 %含む1^ 1 基の合金でぁ るイ ンコネル 690 が使用されることもあった。  Conventional electrode materials for glass melting furnaces used as electrode materials for glass melting furnaces include, for example, Mo-based alloys containing 0.5 to 5% of Cu: 10 to 60 Ba (Japanese Patent (JP-A-49-88739) and a rit-based alloy containing 1 to 20% of R h and 0.5 to 5% of W (JP-A-53-51124). And those using Ni-based alloys. And for Ni-based alloys, Cr is about 30%,? Inconel 690, a 1 ^ 1 alloy containing about 9% of 6, was sometimes used.
この種のガラス溶融炉に使用される電極は、 溶融ガラス中に おいて通電された状態で使用されることから、 通電下における 溶融ガラス中での耐侵食性に優れていることが必要であると共 に、 溶融炉の操作性を向上させるために高融点であることが要 求されている力;'、 従来の電極材料では耐溶融ガラス侵食性に劣 るとか、 融点が低いとか、 などの課題があり、 例えば前記した 成分をもづ N i 基の台金であるイ ンコネル 690 では必ずしも溶 融ガラスに対する耐食性に優れているとはいえず、 また融点も 1350 程度と低いという課題があつた。  The electrodes used in this type of glass melting furnace must be excellent in erosion resistance in the molten glass under energization because they are used in the molten glass while energized. In addition, the force required to have a high melting point in order to improve the operability of the melting furnace; ', conventional electrode materials are inferior to molten glass erosion resistance, low melting point, etc. For example, Inconel 690, which is a Ni-based base metal based on the above-mentioned components, is not necessarily excellent in corrosion resistance to molten glass, and has a problem that its melting point is as low as about 1350. Was.
木発明は、 このよ うな従来のとく に N i 基 金よりなる電極 材料がもつ課題にかんがみてなされたものであって、 通電下に おいて溶融ガラスに対する耐食性に優れていると共に、 融点が 従来の前述した N i基イ ンコネルの融点である 1 350 °Cより も高 く、 ガラス溶融炉の電極素材と して適したものである N i基の ガラス溶融炉用電極材料を提供することを目的と している。 The wood invention is based on such a conventional electrode made of a Ni fund. It was made in view of the problems of materials, and has excellent corrosion resistance to molten glass when energized, and has a melting point higher than that of the above-mentioned conventional Ni-based inconel, 1350 ° C.

発 明 の 開 示  Disclosure of the invention
本発明に係る通電下における溶融ガラス中での耐侵食性に優 れたガラス溶融炉用電極材料は、 重量％で、 C r ： 2 5〜4 〇 %、 C o ： 1 0〜 4 5 %、 必要に応じて T i ： 0 . 1 〜 1 . 5 %、 同じく必要に応じて R E M (希土類元素） のうちから選ばれる 1種または 2種以上の元素 ： 0 . 01〜 0 . 50%を含み、 残部 N i お よび不可避不純物よりなる化学成分組成の構成としたことを特 徵としている。  The electrode material for a glass melting furnace having excellent erosion resistance in molten glass under energization according to the present invention is as follows: Cr: 25 to 4% by weight; Co: 10 to 45% And, if necessary, Ti: 0.1 to 1.5%; and, if necessary, one or more elements selected from REM (rare earth elements): 0.01 to 0.50%. In particular, it is characterized by having a chemical composition consisting of the balance Ni and unavoidable impurities.
次に、 本発明に係る通電下における溶融ガラス中での耐侵食 性に優れたガラス溶融炉用電極材料の化学成分組成 （重量％) の限定理由について説明する。  Next, the reasons for limiting the chemical component composition (% by weight) of the electrode material for a glass melting furnace having excellent erosion resistance in molten glass under energization according to the present invention will be described.
C r ： 2 5〜 4 0 %  Cr: 25 to 40%
C rはガラス溶融炉においてガラスの通電溶融に用いられる 電極の耐食性を確保するために添加する元素であり、 このよう な電極の耐食性を確保するために 2 5 %以上とした。 しかし、 あまり多く添加しても効粜が飽和するだけでなく 、 かえって電 極の融点 ¾·降下させたり、 靭性を劣化させたりするので 4 0 % 以下とした。  Cr is an element added to secure the corrosion resistance of the electrode used for energizing and melting the glass in the glass melting furnace, and is set to 25% or more to secure the corrosion resistance of such an electrode. However, even if too much is added, the effect is not only saturated, but also the melting point of the electrode is lowered and the toughness is deteriorated.
C o ： 1 ひ〜 4 5 %  C o: 1 day ~ 45%
C oは電極の融点を高めてガラス溶融炉の操作性を向上させ ると共に、 通電下における溶融ガラス中での耐食性を向上させ るのに有効な元素であり、 このような融点の向上ならびに耐食 性の向上の効果を得るために 1 o%以上とした。 しかし、 あま り多く添加しても効果が飽和するだけでなく、 かえって電極の 靭性を劣化させるので 4 5 %以下と した。 Co increases the melting point of the electrode and improves the operability of the glass melting furnace. In addition, it is an element effective for improving the corrosion resistance in the molten glass under energization. In order to obtain such an effect of improving the melting point and the corrosion resistance, the content is set to 1% or more. However, adding too much not only saturates the effect, but rather degrades the toughness of the electrode, so the content was set to 45% or less.
T i : 0.1 〜1.5 %  T i: 0.1 to 1.5%
T i は電極の通電下における溶融ガラスに対する耐食性を向 上させると共に、 スケールのはく り性を良好なものとするのに 有効な元素であり、 このような耐食性の向上ならびにスケール のはく り性の向上の効果を得るために必要に応じて 0.1 %以上 添加してもよい。 しかし、 多量に添加しても効果が飽和し、 む しろ電極の融点を降下させるので、 添加すると しても 1.5 %以 下とする必要がある。  T i is an element effective in improving the corrosion resistance of molten glass to the molten glass when the electrode is energized, and also in improving the releasability of the scale. 0.1% or more may be added as necessary to obtain the effect of improving the properties. However, even if it is added in a large amount, the effect is saturated, and the melting point of the electrode is rather lowered. Therefore, even if it is added, it must be 1.5% or less.
R E M (希土類元素） のうちから選ばれる 1種または 2種以上 0.01〜！ ).5096  One or more selected from R E M (rare earth elements) 0.01 ~! ) .5096
R E Mは電極の通電下における溶融ガラス中での耐食性を向 上させるのに有効な元素であるので、 このような効果を得るた めに必要に応じて 0.01%以上添加してもよい。 しかし、 多量に 添加しても効果が飽和し、 かえつて電極の靭性を劣化させるの で、 添加すると しても 0.50%以下とする必要がある。  REM is an element effective for improving the corrosion resistance in molten glass when the electrode is energized. Therefore, 0.01% or more may be added as necessary to obtain such an effect. However, even if it is added in a large amount, the effect is saturated and the toughness of the electrode is rather deteriorated. Therefore, even if it is added, it must be 0.50% or less.
N i ： 残部 N i: Rest
N i は通電下における電極の溶融ガラス中での耐侵食性を確 保すると共に、 融点が高いためにガラス溶融炉の操作性を向上 させるのに有効であるので残部と した。  Ni was used as the balance because it ensures the erosion resistance of the electrode in the molten glass under energization and is effective in improving the operability of the glass melting furnace due to its high melting point.
本発叨に係るガラス溶融炉用電極材料は上述した化学成分組 成を有するものであり、 融点が高く耐食性にも優れた N i を基 地と し、 電極の溶融ガラスに対する耐食性を確保するために C rを適量添加すると共に、 電極の融点の向上ならびに溶融ガ ラスに対する耐食性の向上をはかるために C oを適量添加し、 耐食性のより一層の向上をはかると共にスケールのはく り性を 向上させるために必要に応じて T i を適量添加し、 ボイ ドを内 部にとどめることによって耐食性のより一層の向上をはかるた めに必要に応じて R E M (希土類元素） の 1種または 2種以上 を適量添加するものとしているので、 通電下における溶融ガラ ス中での耐侵食性に優れたものになっていると共に、 融点が高 いことから溶融炉の操作性を向上させるという作用がもたらさ れる。 The electrode material for a glass melting furnace according to the present invention is composed of the above-mentioned chemical components. It is based on Ni, which has a high melting point and excellent corrosion resistance, and adds an appropriate amount of Cr to ensure the corrosion resistance of the electrode to molten glass. An appropriate amount of Co is added to improve the corrosion resistance of the glass, and an appropriate amount of Ti is added as needed to further improve the corrosion resistance and improve the removability of the scale. In order to further improve the corrosion resistance by keeping it inside, an appropriate amount of one or more REM (rare earth element) is added as necessary, so that the In addition to the high erosion resistance, the high melting point has the effect of improving the operability of the melting furnace.
