摘要: 对钢厂6 t电弧炉+LF+VOD+3 t ESR生产的40 mm×40 mm~80 mm×80 mm X20Cr13不锈钢方钢棒材(/%:0.17~0.22C,0.30~0.80Mn,0.10~0.50Si,0.30~0.80Ni,12.5~14.0Cr)随机抽取89炉次,进行化学成分与力学性能的统计回归分析,得到了该类钢材成分与其力学性能的定量回归关系式:σs=704.9+121.9[Ni]-84.9[Mn];σb=638.7+51.1[Ni]-40.5[Mn]+16.9[Cr];A=81.8-24.8[C]+2.7[Mn]-4.4[Cr];Z=49.4+47.5[C]+4.8[Si]+4.3[Ni];AKV=-90.8-55.8[Mn]+10.2[Cr]+154.1[Si]。如工艺参数和棒材规格等因素改变时,应重新回归分析,修正方程系数。

Abstract: The statistic regression analysis on chemical composition and mechanical properties of random sampling 89 heats of steel X20Crl3 (/% : 0. 17 ~0. 22C, 0. 30 ~0. 80Mn, 0. 10 ~0. 50Si, 0. 30 ~0. 80Ni, 12.5 ~ 14. OCr) 40 mm x 40 mm ~ 80 mm x 80 mm square bar products produced by 6 t EAF + LF + VOD +3 t ESR process at steelworks has been carried out to get the quantitative regression relation between chemical composition and mechanical properties of this steel series:σs=704. 9 + 121. [Ni] -84.9[Mn];σb = 638. 7 + 51. 1 [Ni] -40.5[Mn] + 16. 9 [Cr] ; A=81.8 -24.8 [C] +2.7[Mn] -4. 4[Cr]; Z = 49. 4+47. 5[ C] +4. 8 [Si] +4.3[Ni]; A kv= - 90. 8 - 55. 8 [ Mn] +10.2[Cr] + 154. 1 [ Si]. As the process parameters and size of bar products change, the re-regression analysis should be carried out to revise the equation factors.
