摘要
0Cr16Ni5Mo钢由6 t真空感应炉+电渣重熔工艺冶炼,并锻造成Φ120-160 mm钢材,终锻温度≥900℃,力学性能试样经950℃1 h空冷+520℃4 h回火处理。对该钢47炉次的棒材回归分析,得到了0Cr16Ni5Mo钢材成分与力学性能的定量回归关系式:σ_s=-1043.3+5507.6[C]-1 177.0[Si]+212.6[Ni]+1 160.3[Mo];σ_b=-648.2+4 136.7[C]-424.7[Si]+137.2[Ni]+1 018.4[Mo];A=11.9-137.6[C]+25.1[Si]-4.9[Ni]-2.5[Cr]-29.9[Mo];A_(kv)=-473.3-451.3[Si]+103.3[Ni]+321.3[Mo],其显著性水平为0.1。
The test steel 0Cr16Ni5 Mo is melted by a 6 t vacuum induction furnace + electro-slag remelting process,forged to φ120-160 mm steel products,finishing forging at ≥900℃,and the samples for mechanical properties test are treated at 950 ℃ for 1 h,air cooling + tempered at 520℃ for 4 h air cooling.The quantity regression relationships between composition and mechanical properties of products of steel 0Crl6Ni5 Mo are obtained by regression analysis on steel products of 47 heats that are σ_s =-1 043.3 +5 507.6[C]-1177.0[Si]+212.6[Ni]+1 160.3[Mo],σ_b =-648.2+4 136.7[C]-424.7[Si]+137.2[Ni]+1018.4[Mo],A = 11.9-137.6[C]+25.1[Si]-4.9[Ni]-2.5[Cr]-29.9[Mo]and A_(Ky) =-473.3-451.3[Si]+103.3[Ni]+321.3[Mo],its significance level is 0.1.
