Abstract：The welding steel H08A is the low carbon, low silicon and low aluminum steel. And there are some common problems in the production of domestic steel mills, such as poor continuous casting ability and easy formation of bubble in casting billet. The deoxidation technology, refining slag control technology, casting performance and subsurface blowholes control were researched combined with the equipment and technology condition. The producing technology of H08A steel was established by converter to billets. Industrial tests showed that the subsurface blowholes and amount of inclusions were effectively controlled. The continuous casting time in a tundish was improved from 90- 180 to 360- 405 min. The tension failure of H08A steel rod was not appeared in wire drawing process. The new technology met the requirement of the industrial producing.
