高炉风口切割质量的好坏,直接影响高炉的质量。由于风口区的炉体为锥形(图1),采用割炬直接切割时,操作者不但需要不断地移动位置,而且还要不断地改变割炬的角度,使切割质量得不到保证,从而影响了安装与焊接质量。为此而研制的高炉风口法兰安装切割 Blast furnace tuyere cutting quality, a direct impact on the quality of the blast furnace. As the tuyere area of ​​the furnace body is tapered (Figure 1), the direct cutting torch, the operator not only need to constantly move the position, but also continue to change the torch angle, so that cutting quality can not be guaranteed, and thus Affected the installation and welding quality. For the development of blast furnace tuyere flange installation and cutting
