复吹转炉底吹供气元件吹堵复通装置及方法
摘要：
本发明属于钢铁冶金领域，涉及转炉复吹炼钢装置。本发明所述的复吹转炉底吹供气元件吹堵复通装置由空气脱水器、气动快速切断阀、气动调解阀、气体流量计、压力检测仪、计算机控制系统、吹堵气源及输气管路组成；并由输气管路相互连接。所述的吹堵复通方法是以空气为吹堵气源，将空气吹入已堵塞的底吹供气元件中，利用空气中20％的氧气将底吹供气元件中的堵塞物——“渣－金属”蘑菇头不断氧化，使“渣－金属”蘑菇头保持合理的形状，保证底吹供气元件寿命与炉衬同步。吹堵用的空气的压力为0.4－3.0MPa，流量为10－300NM3/h。
摘要（英）：

This invention blow-stop ventilation device of a bottom blow gas supply element of a multi-blow converter is composed of an air dehydrator, a pneumatic fast cut valve, a pneumatic regulation valve, a gas flowmeter, a pressure tester, a computer control system, a blow-step gas source and gas transportation pipe lines interconnected by the gas transportation pipe lines. Said method takes air as the gas supply element and utilizes 20% oxygen in the air to oxidize the blockage-slag-metal mushroom head continuously to keep it at reasonable state to ensure the life time of the supply element the same with the converter lining.
