Control Measures for Folding Defects of Seamless Steel Tubes

However, in the production process of seamless steel pipe, there are also some problems, such as folding defects of seamless steel pipe, and brittle inclusions are the main reason for the formation of outer folding. In view of the problem of external folding of seamless steel tubes, it is analyzed that there are serious brittle inclusions in the production of continuous casting billets. Therefore, in production and processing, processing must be carried out according to certain production methods and methods to ensure that they can fully play well in use. The role and value of the corresponding control measures:

1. Converter smelting process:

Ensure that a carbon hit is hit once, avoiding post-blowing, and the endpoint carbon control is >0.10%;

Improve the effect of converter slag, strictly control the amount of slag, use slag in the process of exiting, the thickness of ladle slag after tapping is
