Key smelting points to guarantee success production of ABS DH32 steel plates steel plate

BBN steel is world class ABS DH32 steel plates supplier in China. The smelting points of BBN steel's ABS DH32 steel plates as below:

(1) Pre desulphurization of molten iron.
(2) The end point carbon of the converter is controlled within 0.06%~0.10%.
(3) Cinder tapping, ladle and synthetic slag.
(4) Ladle deoxidation alloying. The content of acid soluble aluminum is 0.004% ~ 0.005% in the steel before entering the refining station.
(5) Refining station feed aluminum line, the content of acid soluble aluminum in steel is stable from 0.02% to 0.04%, and the w[Ca]/w[A1] ratio of calcium feed line is 0.1.
(6) Ensure the stirring time of weak argon blowing, and promote inclusions float up fully.
(7) Full casting protection during whole process of continuous casting.

Notes: ABS DH32 steel plates residual elements amount: w[Cu] = 0.35%; w[Cr] = 0.20%; w[Ni] = 0.40%; w[Mo] = 0.08%.

The above smelting points of BBN steel lay a solid foundation of high quality ABS DH32 steel plates. And it is also one of the reason why BBN ABS DH32 marine steel plates are so popular in ship building industry all over the world.
