S355J2 steel plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the GL-EH 36 offshore engineering steel rolling speed is 1.6-2.0m/s, the single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.As a basic building material, steel plates are currently widely used in automobiles, shipbuilding, chemical industry, aerospace and other fields. Reasonable selection of flaw detection methods to ensure the quality of GL-EH 36 offshore engineering steel steel plates is of great significance to safe production. Common defects of steel plates are folding, inclusion, shrinkage, air bubbles, delamination and cracks. These problems can be discovered in time through flaw detection.

Do a good job of thought introduction based on people. Human based management is the most important link in standardizing employee behavior management. In daily behavior management, we should establish the central position of human and play an important role of human. Employees are not only the builders and exercisers of corporate culture, but also the executors of code of conduct. The code of conduct should be finally implemented into the thoughts and actions of employees.
