Abstract
一种漂移式电极密封圈外形为一圆环状体，由耐火材料浇筑而成。将本实用新型置于耐火材料预制三角区和电极之间，即可起到漂移式密封作用，使得电极孔密封性良好。可广泛作为炼钢厂用电弧炉的密封装置。
Description
技术领域：
本实用新型涉及炼钢厂用电弧炉的密封装置。
背景技术：
电弧炉炉盖三角区现多采用耐火材料预制三角区，工作中受电极辐射或高温烟气冲刷，电极孔会逐渐扩大，导致密封性差，炉内热损失增大，为了电极孔密封性良好，只有更换耐火材料预制三角区，这样又带来生产成本的增加。解决这一问题已成为急需。
实用新型内容：
为了克服现有技术的不足，设计一种置于耐火材料预制三角区和电极之间的密封装置，起到漂移式密封作用。漂移式电极密封圈外形为一圆环状体，由耐火材料浇筑而成。将本实用新型置于耐火材料预制三角区和电极之间，即可起到漂移式密封作用，使得电极孔密封性良好。
附图说明：
图1为本实用新型正面视图；
图2为本实用新型工作状态视图。
具体实施方式：
为本实用新型的一个最佳实施例，如图，漂移式电极密封圈外形为一圆环状体1，由耐火材料浇筑而成。将本实用新型置于耐火材料预制三角区2和电极3之间，即可起到漂移式密封作用。
