针对国外高炉出现的斜孔以及超长斜孔加工困难且加工精度难以保证的难题,通过三维模型分析和实践论证,利用一些常用的机具进行组装,并与传统的钻孔工艺配合,最终加工出了满足设计要求精度的斜孔,可为同类孔洞的加工提供经验。
According to the problems of slant holes and extra-long slant holes in foreign blast furnaces that are difficult to process and the machining accuracy is difficult to be guaranteed, the author uses three-dimensional model analysis and practical demonstration to assemble them with some commonly used tools and work with the traditional drilling technology to finally produce Angled holes that meet the design requirements accuracy provide experience for the processing of holes of the same type.
