研究了连铸焊条钢H08包样内部气孔面积和表面上涨值与钢液成分之间的关系，生产中通过包样表面上涨值来判断和调整钢液的脱氧度，避免连铸过程中铸坯产生皮下气泡缺陷。
The relationship between the inner stomatal area and the rising value of molten steel in the continuous casting electrode steel H08 sample and the composition of the molten steel was studied. The production value of the sample surface was used to judge and adjust the deoxidation degree of the molten steel and to avoid the slab Subcutaneous bubble defects.
