How to protect the ABS D offshore steel plate from cracking

Longitudinal cracks and other crack defects on billet surface are one of the main reasons for the modification of steel plate into unqualified steel. Crack defects are produced during smelting and casting of steel. The main reason for cracking of ABS D offshore steel plate is that the moisture content of molten steel is related to the mold and water cooling process during steelmaking process.

Since we have found the cause of cracks in the ABS D offshore steel plate, we can take measures to avoid cracks in the ABS D marine grade steel plate. For example:
1. The grinding surface of ABS D billet ensures no cracks during billet entry.
2. In the smelting process, we should strengthen the control of nitrogen, aluminum and other elements.
3. The casting speed and the two cooling processes in the continuous casting process are improved.
4. In addition, sharpening the continuous casting billets with cracks is also a good method.

From the above description, you may have a general understanding of the cracks in the ABS D offshore steel plate. If you want to know more, please feel free to talk with us.
