Description
【０００１】[0001]
本考案は可撓性耐火ボードを予じめ周設、固着した溶融金属容器用上ノズル又 はポーラスプラグに関する。 The present invention relates to an upper nozzle or a porous plug for a molten metal container in which a flexible refractory board is preliminarily installed and fixed.
【０００２】[0002]
従来溶融金属容器インサートノズルの装着に当っては、インサートノズル外周 に手作業にてモルタルを塗布し、ノズル受け煉瓦に手作業によりセットしている 現状である。 Conventionally, when mounting the insert nozzle of a molten metal container, the mortar is manually applied to the outer periphery of the insert nozzle and manually set on the nozzle receiving brick.
【０００３】[0003]
以上のように手作業によるため、セット作業の標準化が難しく、機械化又は自 動化が困難であり、特にモルタル塗布では塗布したモルタルが脱落したり、所定 の位置からずれたりする場合があり、インサートノズルのセット作業、従ってス ライドバルブ装置の組立作業自動化のネックとなっている。 As described above, it is difficult to standardize the setting work because it is manual work, and it is difficult to mechanize or automate it.In particular, when applying mortar, the applied mortar may drop out or shift from the prescribed position. This is a bottleneck in automating the nozzle setting work, and thus the assembly work of the slide valve device.
