Description

锻铸结合氧枪喷头
                         技术领域
本实用新型涉及转炉炼钢用的氧枪喷头。
                         背景技术
目前，我国氧枪喷头的生产方法主要有两种，一种是用工业紫铜整体铸造而成，另一种是用工业紫铜冲压成各个部件，然后组装在一起。
铸造喷头由于受铸造工艺的限制，喷头的纯度、密度、导热性能很难满足使用要求，紫铜在铸造过程中产生的气孔、疏松、裂纹、毛刺、飞边等铸造缺陷，不可避免地影响到喷头的水冷和导热，使喷头的寿命降低。而且氧孔出口部位在使用过程中的变形，也影响氧枪的吹炼效果。
冲压组装式喷头，部件较多。各个部件除钢管外，全部用紫铜冲压、车削成型，然后组装在一起。这种喷头虽然使用寿命长，吹炼效果好，但加工工艺复杂，焊缝较多，存在安全隐患，而且制造成本较高，难以推广使用。
                         发明内容
本实用新型的目的是针对现有技术的不足，提供一种结构合理、使用寿命长、成本低廉的锻铸结合氧枪喷头。
为实现上述目的，本实用新型采用如下技术方案实现：
锻铸结合氧枪喷头，由喷头头冠、喷头内体、外管、中管、内管组成，其特征在于：喷头内体由氧气盘、氧柱和导水板用钢质材料整体铸造成型，喷头头冠是用紫铜整体锻造成型，喷头内体和喷头头冠通过水平接口钎焊焊接而成。
本实用新型的有益效果是：
1)喷头内体将氧气盘、氧柱和导水板整体铸造成型，简化了结构，增强使用寿命及喷头的水冷效果；采用钢制结构，降低了制作成本；
2)喷头内体和喷头头冠通过水平接口焊接，相比现有的斜焊缝，具有加工简便的优点。
                         附图说明
图1是锻铸结合氧枪喷头的结构示意图。
图2是锻铸结合氧枪喷头的结构俯视图。
                         具体实施方式
见图1、图2，图1是图2的A-A向剖视图。锻铸结合氧枪喷头，由喷头头冠1、喷头内体4、外管2、中管3、内管5组成，喷头内体由氧气盘6、氧柱7和导水板8用钢质材料整体铸造成型，喷头头冠是用紫铜整体锻造成型，喷头内体和喷头头冠通过水平接口钎焊焊接而成。内管5、中管3分别与喷头内体4氩弧焊接，外管2与喷头头冠1氩弧焊接。
