| 摘 要： | 转炉用托圈的轴头与围板焊接处严重开裂，通过对其材质、结构、工艺进行分析，找出接头断裂的订原因，一方面是由于焊缝连接件厚度相差悬殊，另一方面是由地缝未焊透，这两方面原因造成应力集中。为了解决这个问题，将焊接接头由角接改为对接，工艺上采取清根措施 保证焊缝全焊透。通过改进，避免了焊缝开裂问题。

| Abstract: | The welding juncture of the axis head and the surrounded plate in the holding circle of bessemer converter crack severely .By means of analysis to the material,the structure and the process,we find out that one of the main reason of crack is the thickness of welding plates vary a lot, the other is that it isn't penetrable for welding. In order to solve the problem , we adopt butt joint instead of fillet joint and in the same time take back chipping for penetrating seam in the process . Thus,the crack is avoided. |
