摘要

在热轧HP295气瓶钢板(%:0.13～0.18C、0.80～1.00Mn、≥0.015Nb、≥0.010Ti)抗拉强度统计分析的基础上

采用多元线性回归方法建立了碳当量Cehp=c+0.242 6Mn-0.353Si、板厚h和卷取温度CT与HP295钢板抗拉强度σb之间的线性关系式:σb=499.1Cehp-17.72h-0.728CT+836.68。检验结果表明

HP295钢板抗拉强度的计算值与测量值之间的相对误差≤8.67%

满足计算精度要求。

Abstract

Based on the statistics and analysis on tensile strength of HP295(0.13～0. 18C

0.80～1.00Mn

≥ 0.015Nb

≥0.010Ti)hot rolled steel strip for gas bottle by using multiple regression analysis method

the linear equation of tensile strength gu of HP295 steel strip with carbon equivalent.Cop=C+0.2426Mn-0.353Si

strip thickness h and coiling temperature CT:04=499. 1Cp- 17.72h-0.728CT+836.68.Examination results showed that relative eror between calculated and measured value of tensile strength of HP295 steel strip was ≤8.67% to meet the requirement for calculated precision.
