Description
技术领域
[0001] 本实用新型涉及电弧炉的零部件，特别涉及一种电弧炉盖。
背景技术
[0002] 电弧炉是利用电极电弧产生的高温熔炼矿石和金属的电炉。气体放电形成电弧时能量很集中，弧区温度在3000°C以上。对于熔炼金属，电弧炉比其他炼钢炉工艺灵活性大，能有效地除去硫、磷等杂质，炉温容易控制，设备占地面积小，适于优质合金钢的熔炼。
[0003] 电弧炉一般包括炉身、炉盖和电极。其中炉盖的设计也有多种，一种是全耐火砖堆砌而成，该种炉盖温度控制效果不好，冷却效果不佳，同时也容易出现垮塌；另一种是全散热金属炉盖，该种炉盖不仅造价高昂，而且由于其散热管道遍布整个炉盖，其冷却过快，温度控制难度高。
实用新型内容
[0004] 本实用新型的目的是提供一种结构强度好，节省材料，温度控制效果好的电弧炉至
ΠΠ O
[0005] 实现本实用新型目的的技术方案是:本实用新型具有本体；其特征在于:所述本体包括支撑架和耐火盖体；所述支撑架包括底圈、顶盖和连接梁；所述底圈围设在顶盖的外部，底圈与顶盖通过连接梁连接在一起；所述耐火盖体固定设置在底圈和顶盖之间且填充满底圈与顶盖之间的间隙；所述顶盖上设有供电极穿过的电极孔。
[0006] 上述顶盖的内部中空；所述本体上固定设有均与顶盖的内部连接相通的进水管和出水管。
[0007] 上述顶盖的上端面高于底圈的上端面。
[0008] 上述顶盖呈圆锥台状；所述顶盖的小端面朝向底圈；所述顶盖与底圈同轴。
[0009] 上述底圈包括连接成一体且相互垂直的围圈和挡圈；所述挡圈与顶盖的小端面平行。
[0010] 上述围圈与挡圈之间设有加强筋。
[0011] 上述耐火盖体由多块耐火砖堆砌而成。
[0012] 上述支撑架包括三根呈一百二十度圆周分布的连接梁；所述各连接梁均与顶盖的大端面和围圈的上端面固定连接。
[0013] 本实用新型具有积极的效果:(I)本实用新型利用支撑架将耐火盖体支撑住，其结构稳定，不容易出现垮塌；(2)本实用新型只在顶盖上设置进水管和出水管，冷却范围缩小的同时，也保证了温度的控制效果更好；(3)本实用新型的顶盖高于底圈，可以大大增强炉盖拱形结构的稳定性；(4)本实用新型利用耐火砖堆砌在支撑架上，可以大大节省耐火砖的使用量，减少制造成本；(5)本实用新型的支撑架只需利用三根连接梁便可实现很高的支撑强度，制造简单。
附图说明
[0014] 为了使本实用新型的内容更容易被清楚地理解，下面根据具体实施例并结合附图，对本实用新型作进一步详细的说明，其中
[0015] 图1为本实用新型的结构示意图；
