摘　　要：采用Mn-Ni-Cu -B系合金 ,在 4 2 0 0mm轧机上实行Ⅲ型控轧 ,以ACC装置进行轧后冷却 ,开发出超低碳贝氏体钢 (ULCB) 5 0mm厚板。其抗拉强度达到 70kg级 ,低温冲击性能优良。这为开发ULCB heavy plate with maximum thickness of 50?mm was developed by applying of Mn-Ni-Cu-B alloy, Ⅲ controlled rolling and cooling in 4?200?mm plate mill by ACC equipment. The steel had a high strength of 70?Kg and low temperature impact toughness. The development of 70?kg ULCB steel has lied a solid foundation to develop 80?kg ULCB steels.
