1) air extraction rate
抽气能力
2) off-gas pressure
抽气压力
1.
The results show that the appropriate off-gas pressures in the periods of emerged arc and submerged arc are -200-250 Pa and -120 Pa, respectively.
结果表明:露弧加热期和埋弧加热期炉盖的合理抽气压力分别为-200~-250Pa和-120Pa;底吹氩气量过小不能在液面上部弥散,而增大到20~50m3。
2.
In the heating period of emerged arc, appropriate off-gas pressure is more than 250 Pa and high temperature zones in the middle of lid is big.
结果表明,进入炉盖内的气体在主体部分流动规律是一致,露弧加热时达到硝烟除尘要求的合理抽气压力为250 Pa 以上,炉盖中部局部高温区域大温度高,埋弧加热期合理抽气压力为200 Pa 左右,炉盖壁面温度低得多,中部温度高温区仅为330 K(57℃)左右。
