The following are the reasons for the surface bubbles of the straightener machine.
The surface bubbles of the straightener are generally the condensation interface of steel elements during the condensation process such as oxygen, hydrogen, nitrogen and carbon.
When it constitutes CO, H2 and N2 gases, if the total pressure is greater than the sum of static pressure and atmospheric pressure, there will be a foam composition.
If these bubbles can't escape the steel quickly, there will be bubble defects on the surface or under the skin of the cast billet of the straightener machine. Lack of deoxidation of continuous casting slab will also cause blisters on the surface or subcutaneous of the straightener machine cast slab.
In addition, other operations also have a certain impact on the shortcomings of bubbles, such as improper control at the end, long tapping time, and high pouring temperature to form bubbles.
