| titleOfInvention | Manufacturing method of fireproof steel plate for building with low yield ratio |
| abstract | (57) [Summary] [PROBLEMS] An object of the present invention is to provide a method for producing a steel which has a low yield ratio and which does not add a large amount of Mo at a low cost and is excellent in 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: 0.25 to 0. 70%, Nb: 0.005-0.04%, Ti: 0.0 05-0.025%, Al: 0.06% or less, N: 0. A slab containing 006% or less and the balance of which is composed of iron and unavoidable impurities is reheated to a temperature range of 1000 to 1200 ° C, and a cumulative reduction amount at 850 to 1000 ° C is 3 Rolling is performed so as to be 0% or more, quenching is performed immediately after rolling, subsequently reheating to a temperature range of 740 to 820 ° C., quenching, and then tempering treatment in a temperature range of 450 to 700 ° C. A method for producing a refractory steel for buildings having a low yield ratio, which is characterized by the following. |
