Super Thick heavy steel plate for marine platform with thickness over 100mm rolled from ingot rolling process has the advantages of low carbon equivalent, high and even quality from surface to inside, good weld ability, excellent comprehensive mechanical properties and so on. Taking advantage of 5000 mm heavy plate rolling mill line with ten thousand tons rolling capacity, and the mill’s other strength and new process such as: heavy reduction rate rolling capacity of the mill(single rolling reduction of more than 50mm), TMCP process the control, PVCP plate shape control, and normalizing treatment after rolling finally, the delivered heavy plate has overall good performance and quality, yield and tensile strength data have reached or exceeded regulatory requirements for marine and shipbuilding heavy plate, and -40 °C impact reached more than 100J. Steel plate’s performance and quality can meet offshore platform demand for using in harsh environments.
