摘要: AH36船板钢的生产工艺流程为120 t BOF-LF-220/250 mm坯连铸-2250 mm轧机轧制。对CSP轧制的控制和新剪切工艺生产的10~24 mm AH36船用开平板钢(/%:0.07C、0.26Si、1.24Mn、0.014P、0.006S、0.031Als、0.028Nb、≤0.290Ceq)和传统10~24 mm AH36船用中板钢(/%:0.13C、0.28Si、1.26Mn、0.024P、0.014S、0.038A1s、0.024Nb、≤0.363Ceq)的力学性能进行了分析和对比。结果表明,0.07%C AH36船用钢开平板的力学性能达到0.13%C传统AH36船用钢中板的力学性能指标,0.07%C AH36钢开平板韧脆性转变温度为-60℃,较传统的0.13%C AH36钢中板韧脆性转变温度-40℃低。0.07%C AH36钢比传统0.13%C AH36钢有较好的工艺性能和较高的尺寸稳定性。

Abstract: The production process flow sheet of steel AH36 for ship is 120 t BOF-LF-220/250 mm slab casting-2250 mm mill rolling. The analysis and comparison on mechanical properties o£ the 10 ~ 24 mm opened plate of AH36 steel for ship (/% : 0. 07C, 0. 26Si, 1. 24Mn, 0. 014P, 0.006S, 0.031 Als, 0. 028Nb, ≤0. 290Ceq) produced by CSP control rolling process and new shearing process and the traditional 10 ~24 mm medium plate of AH36 steel for ship (% : 0. 13C, 0. 28Si, 1. 26Mn, 0. 024P, 0. 014S, 0. 038Als, 0. 024Nb, ≤0. 363Ceq) have been carried out. Results show that the mechanical properties of opened plate of 0. 07 % C AH36 steel for ship is up to the index of mechanical properties of traditional medium plate of 0. 13% C AH36 steel for ship, and the tough-brittle transition temperature -60 °C of 0. 07% C AH36 opened plate for ship is lower than that - 40 ℃ of traditional 0. 13% C AH36 steel medium plate for ship. As compared with traditional 0. 13% C AH36 steel the 0. 07% C AH36 steel has better workability and higher size stability.
