Abstract��The effects laws of non-metallic inclusion and bainite structure on the elongation of heavy and medium plate are analyzed systematically by means of microscope, electron scanning microscope and metal original position analyzer on the basis of the specimen from big samples. Test results show that non-metallic inclusion and bainite structure in the steel are main factors affecting the elongation. Non-metallic inclusions influence plate elongation reduction heavily in type, content and distribution, especially sulphide and silicate type inclusions. Test results also present banded bainite structure has a prominent effect on plate elongation reduction and they have close correlation.
