易すく、酸素用ノズル及び燃料用ノズルが詰
り、バーナー機能の低下を招き、悪化すれば使
用不可となつた。 Since the burner tip (barrel) is made of copper or stainless steel, it is easy for splash, slag, etc. to adhere to it, clogging the oxygen nozzle and fuel nozzle, leading to a decrease in burner function, and if the burner gets worse, it becomes unusable.
溶損やスプラツシユ付着した場合の補修が困
難で、メンテナンスに時間がかかり、かつコス
トがかさむ。 Repairs are difficult in the event of melting damage or splashes, making maintenance time-consuming and costly.
上記欠点によりバーナーが満足に使用出来な
いと製鋼能率が低下する。 If the burner cannot be used satisfactorily due to the above-mentioned drawbacks, steel manufacturing efficiency will decrease.
そこで本願出願人は、先に実願昭57−197646号
明細書において、上記欠点を解消すべく、バーナ
ーボデイーの砲身を黒鉛を主成分とする耐熱部材

また炉内高温雰囲気の漏洩等により、砲身が酸化
し、バーナーの寿命が低下するという問題が生じ
た。 However, in the above-mentioned heat-resistant burner device, there is a slight gap between the gun barrel of the burner body and the heat-resistant member, and the flame in the furnace backfires in the gap.
Additionally, leakage of the high-temperature atmosphere inside the furnace caused the gun barrel to oxidize, resulting in a shortened burner life.
そこで、本考案は、上記問題点を解消した耐熱
