| titleOfInvention | Manufacturing method of fireproof steel plate for building with low yield ratio |
| abstract | (57) [Summary] [Object] An object of the present invention is to provide a method for manufacturing a thick plate (50 mm or more) having a low yield ratio and excellent high temperature strength. [Composition] C: 0.05 to 0.15% by weight, Si: 0.6% or less, Mn: 0.8 to 1.6%, P: 0.03 % Or less, S: 0.005% or less, Mo: 0.35 to 0. 80%, Ti: 0.005 to 0.025%, Al: 0. 06% or less, N: containing 0.006% or less, after the steel balance of iron and unavoidable impurities hot rolling, Ac 3 After heating to the temperature range of ~ 1000 ° C, quenching, followed by 7 Reheating in a temperature range of 40 to 820 ° C., quenching again, and then tempering in a temperature range of 450 ° C. to Ac 1 transformation point. Fire resistance for construction with a low yield ratio of 50 mm or more. Steel manufacturing method. |
