Research on Steel Plate Shape Control Technology for High Strength Pipeline
With the continuous improvement of pipeline transportation efficiency,large thick walls,large diameters,and high grade steel have become the trend of pipeline steel development.In order to meet the requirements of high strength and toughness,the amount of alloy added and the difficulty of rolling process are increasing.The final cooling temperature control is moving towards high cooling rate and ultra-low temperature control,resulting in an increase in the uneven structure and stress inside the steel plate,an increase in the difficulty of plate shape control,and severe cracking.To solve such problems,actual production data such as billet heating system,initial rolling process,finishing rolling process,cooling parameters,and composition design were statistically analyzed to determine the relationship between plate shape and develop effective measures to control high-level pipeline plate shape problems.
