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 LR DH32 shipbuilding steel plates 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 LR DH32 shipbuilding steel plates 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.
Although both HSLA steel plate and carbon steel plate belong to carbon structure and low alloy structure steel, there are some differences. First of all, LR DH32 shipbuilding steel plates, HSLA steel plate and carbon steel plate differ in strength, hardness and use. In terms of strength, the strength of HSLA steel plate is higher than carbon steel plate. In terms of hardness, the hardness of HSLA steel plate is also higher than that of carbon steel plate. And in the scope of use, the advantages of HSLA steel plate are more prominent, so the scope of HSLA steel plate use is more extensive than that of carbon steel plate.
