摘要
在舞钢进行了82mm厚1 4Cr1MoR( % :0 . 1 5C ,1 . 48Cr,0 . 57Mo)钢板的工业性热处理工艺试验。试验结果表明,采用9℃/min速度加热,93. 0℃奥氏体化2 4min/mm ,870℃水淬,680℃保温3 0min/mm回火、空冷、热处理后,钢的组织为索氏体,室温抗拉强度590～650MPa ,屈服强度44 .5～485MPa ,延伸率2 7%～2 8% ,断面收缩率73 %～75% ,2 0℃横向冲击功1 73～2 1 2J,580℃σ0 .2 为2 95～3 3 0MPa。钢板各部分性能均匀,满足标准要求。
The experiment of commercial heat treatment process for 82 mm plate of steel 14Cr1MoR (0.15C-1.48Cr-0.57Mo) has been carried out at Wuyang Iron and Steel. The test results showed that heat- treated with 9 ℃/min heating up speed, austenite conditioning at 930 ℃ for 2.4 min/mm, water quenching at 870 ℃, and tempering at 680 ℃ for 3.0 min/mm , air cooling, the structure of steel was sorbite, of which the ambient tensile strength was 590～650 MPa, yield strength 445～485 MPa, elongation 27%～28%, reduction of area 73%～75%, cross impact energy 173～212 J, and the σ 0.2 at 580 ℃ was 295～330 MPa. The properties of different parts of plate were uniform up to the requirement of standard.
