Inclusions of RH refining tundish slab and plate are investigated on API‐X70 pipeline steel. It is found that reoxidation in tundish converts the well‐modified liquid calcium aluminates into solid Al 2 O 3 ‐rich inclusions and the number dramatically increased. Reoxidation in tundish put the calcium treatment and strong capacity of inclusion removal during RH treatment in vain.
