一种转炉底吹供气元件的安装方法

本发明公开一种转炉底吹供气元件的安装方法，是根据短接件外径对转炉炉底底吹孔扩孔使之形成与短接件歇间配合且中心线与其所在的炉底平面或球面的切面垂直；将短接件插入炉底配重铁开口及底吹孔内且上沿与炉壳内表面对焊、下沿与配重铁外表面固定；先砌筑底吹孔周围永久层及下护砖，然后将定位杆插入下护砖内定位并根据下护砖位置砌筑上护砖及炉底工作层、炉身；在炉底搭建安装平台，将底吹供气元件穿过短接件并插入到下护砖和上护砖容纳通道中，随后用耐火泥填充底吹供气元件与短接件的连接缝隙并使之相互固定连接，接着用干镁砂填充底吹供气元件与容纳通道间的缝隙。本发明具有结构简单、连接可靠、可预防渗钢及漏钢事故、安装效率高的特点。 The invention discloses an installation method of a converter bottom blowing air supply element. A converter bottom blowing hole is expanded according to the outer diameter of a short connecting piece so that the converter bottom blowing hole can be in intermittent fit with the short connecting piece, and the center line is perpendicular to the tangent plane of a converter bottom plane or spherical surface where the converter bottom blowing hole is located; the upper edge of the short-circuit piece is in butt welding with the inner surface of the furnace shell, and the lower edge of the short-circuit piece is fixed with the outer surface of the counterweight iron; firstly, a bottom blowing hole surrounding permanen
