摘　　要：通过试验研究了正火控冷(NCC)工艺对厚规格EH36高强海工钢板性能、微观组织及冷弯性能的影响。试验结果表明:应用正火控冷(NCC)工艺后,钢板的强度损失减少明显,断后伸长率略有降低,-40℃低温冲击稳定性改善明显,冷弯性能降低不明显。Influences of normalizing controlled cooling（ NCC） process on mechanical properties,microstructure and cold bending property of thick high-strength steel plate EH36 for marine engineering were studied. The results show that after applying NCC process,the strength loss of plates decreases obviously,the elongation decreases slightly,the low-temperature impact stability at -40 ℃ is improved obviously,and the cold bending property has no obvious decrease.

关 键 词：宽厚板 正火控冷(NCC) 强度损失
