Abstract��The Q390E steel plate of 120 mm��2 750 mm specification was developed based on the 400 mm��2 400 mm continuous casting slab. The clean steel production technology was applied to control the content of harmful elements�� and the dynamic 3D nozzles automatic adjustment�� dynamic 3D secondary cooling and dynamic light pressure were adopted to ensure the quality of the slab. At the same time�� 120mmQ390E steel plate was successfully developed through the technical research of heating�� rolling and cooling. The mechanical performance indexes were superior to the national standard and stable�� especially the low temperature impact performance.
