Abstract : This paper introduces the key control technology and process route of developing hot-rolled coils for X80 steel grade petroleum pipelines by adopting low-carbon composition design and TMCP process . […]

Starting from the influence of the expansion and contraction hydraulic system and the tension control hydraulic system of the coiler on the coiling quality of the strip, by improving the expansion and contraction hydraulic system and the tension control h […]

The corresponding relationship between delamination along the crystal form and phosphorus segregation bands in the fracture of two low-alloy steel sheets (coils) was investigated. As a result, Nong Ming, the embrittlement of segregation zone is the source […]

​​​​​​​Abstract : The strength of DC04 steel is improved by cold rolling deformation, stress relief annealing is carried out in the partly recrystallized area, and the holding time is reasonably controlled. […]

Excerpt: The hot-rolled coiled tube made of SS400 cracked after welding, and the main reason for the cracked coiled tube was found through research and analysis of the cracked sample. […]

Abstract : Aiming at the serious edge breaking phenomenon of hot-rolled SPHC steel in BBN Iron and Steel Co., Ltd. , the causes and prevention measures of edge breaking in hot-rolled coils were studied. […]
