How to avoid the pits on the surface of ABS Grade A ms steel plate

The surface pits of ABS Grade A ms steel plate is one of the reasons for poor surface quality of ABS Grade A shipbuilding steel plates. Since the pits on the surface of ASTM A131 Grade A ms steel plate are so harmful, how do you avoid them?

First, we need to know the cause of the pits on the surface of ABS Grade A ms steel plate.
The unreasonable air-fuel ratio controls the combustion of steel, resulting in the iron oxide attached to the surface of the ABS Grade A ms steel plate and can not be removed. The water pressure is not enough and can not be injected continuously. So it can not remove iron oxide very clearly. During the rolling process of ABS Grade A ms steel plate, the residual iron oxide enters the ABS Grade A plate and forms a surface pit.

Measures to avoid the pits on the surface of ABS Grade A ms steel plate are: adjusting the air-fuel ratio of the heating section; The high-pressure water system is transformed into a high-pressure centrifugal pump. Raise the height of the nozzle on the descaling box and raise the water pressure when descaling.
