Description
本願は、2006年3月16日に日本国に出願された特願2006−72235号に基づく優先権を主張し、その内容をここに援用する。
また、前記溶融ガラス加熱手段は、浸漬型電極および/もしくは電気ヒーターであることが好ましい。
調整槽3の上部空間に、電気ヒーター11に替えて酸素バーナ8,8・・・を設置し、その他は実施例と同じ条件で溶融ガラス23のバッチ処理を行った。得られた成型ガラスから、板状サンプル3枚(C(a)〜C(c))を切り出し、実施例と同様に水分濃度を測定した。その結果を表1に示す。サンプルC(a)〜C(c)は、700ppm前後の水分濃度であった。
Claims (6)
- 溶融槽を備えるガラス溶融炉を用いたガラス溶融方法であって、
調整槽をこの溶融槽における溶融ガラス流の下流に配置し、調整槽の温度と調整槽への導入ガス量を調整することによって、雰囲気ガスと溶融ガラス表面との界面での水分濃度の平衡状態を制御し、溶融ガラス中の水分濃度を調整する工程を有するガラス溶融方法。 - 前記溶融槽において酸素バーナーを用いて原料ガラスを溶融する請求項1記載のガラス溶融方法。
- 前記調整槽を正圧に維持する請求項1記載のガラス溶融方法。
- 原料ガラスを溶融するガラス溶融炉であって、
溶融槽と、
該溶融槽で溶融させたガラスの水分濃度を調整するための調整槽と、
該調整槽へ前記溶融槽から溶融ガラスを流すためのスロート部と、
前記溶融槽の上部空間と前記調整槽の上部空間とを隔絶するための仕切り壁とを有し、
前記調整槽は、前記仕切り壁より溶融ガラス流の下流に設けられた仕切り堰、溶融ガラス温度を調整するための溶融ガラス加熱手段、雰囲気ガス導入口及び雰囲気ガス加熱手段を備えており、
前記雰囲気ガス加熱手段が電気ヒーターもしくは前記溶融槽からの燃焼排ガスとの熱交換であるガラス溶融炉。 - 前記溶融槽が酸素バーナーを具備している請求項4記載のガラス溶融炉。
- 前記溶融ガラス加熱手段が浸漬型電極および/もしくは電気ヒーターである請求項4記載のガラス溶融炉。
