| 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. |
