Description

铁水脱硫喷镁剂枪
技术领域
本发明属于铁水脱硫处理装置范畴，特别涉及一种铁水脱硫喷枪。
背景技术
现有铁水脱硫喷枪均存在料耗高、脱硫剂利用率低、喷枪本体笨重、脱硫成本高等缺点。由于存在上述缺点，导致无法顺利地进行炉外脱硫，尤其是在大型的(等于或大于160t)铁水包中，其结构上的缺陷更加明显。
发明内容
本发明所要解决的技术问题在于提供一种结构简单、脱硫剂利用率高、运行费用低廉、脱硫效果良好的铁水脱硫喷枪。
本发明的技术解决方案可依如下方式实现：
一种铁水脱硫喷镁剂枪，其特点是，含有：管道、枪本体、位于枪本体外侧的耐火材料层、附在枪本体外又置于耐火材料层内的骨架；所述管道装配在枪本体内。
在所述管道的出口端配有耐火套管。所述管道的出口端为喇叭口结构。
所述管道置于枪本体内，且与枪本体的内壁保持一定距离。
所述管道的内径等于或大于镁颗粒直径的10倍，其长度不小于管道内径的420倍。
本发明所述耐火材料层的原料物含有下列组分(重量百分含量)：
莫来石                                45～67％
矾土水泥                              20～27％
钢纤维                                2～6％
水                                    14～20％
本发明结构简单、脱硫剂利用率高、运行费用低廉、脱硫效果好，能稳定地将颗粒镁导入铁水中并取得很高的脱硫指标。
附图说明
图1为本发明的整体结构示意图；
图2为本发明的另一种结构方式出口端结构示意图；
图3为本发明的实际运行状态图。
具体实施方式
本发明含有：管道1、枪本体2、位于枪本体2外侧的耐火材料层4、附在枪本体2外又置于耐火材料层内的骨架3；所述管道1可固定装配在枪本体2内，管道1也可以可拆卸方式配装于枪本体2内。在所述管道1的出口端配有耐火套管5。所述管道1的出口端为喇叭口结构。所述管道1置于枪本体2内，且与枪本体2的内壁保持一定距离。所述管道1的内径等于或大于镁颗粒直径的10倍，其长度不小于管道1内径的420倍。
本发明所述管道1用于输送镁剂，骨架3及枪本体2均采用钢质材料。耐火套管5可防止管道1的管子与铁水接触。耐火套管材料耐铁水浸润的性能很好，且有很高的耐激冷激热强度，这就保证了在向铁水中喷吹镁剂时喷枪出口处的管道有稳定的几何形状。当严重磨损时，可以迅速更换一个新耐火套管而不必更换价格很贵的整个喷枪。耐火套管5的长度为管道1内径的2～8倍，若小于2倍时管道1就可能与铁水相接触，而大于8倍时更换耐火套管又有困难，因而均不合理。所述输送镁剂管道1置于钢结构的枪本体2内且与钢结构的枪本体2的内壁保持一定距离，这样就能保证与输送镁剂管道1的隔热，防止输送镁剂管道1受热和防止镁剂在输送镁剂管道1上粘着。所述输送镁剂管道1的出口端可为喇叭口形状，所述输送镁剂管道1的内径等于或大于镁颗粒直径的10倍，其长度不小于输送镁剂管道1内径的420倍。
本装置在工作时先从喷镁罐6向装入铁水的铁水包7内通过脱硫喷枪的软管供出气体，流量按每小时15～30立方米向每平方米熔体表面供气。然后把脱硫喷枪插入铁水中达到必要的深度后，通过喷镁罐系统经导镁管路8向喷枪内供出镁剂而被导入铁水中，给出镁质的物料量按1-3kg/吨铁控制。9为铁水。
