| 摘 要： | 为满足用户加工硬度的特殊需求(硬度≤210HBW),降低6CrW2Si钢硬度,本文利用连轧厂实际辊底式退火炉进行了不同退火温度的退火试验,并借助金相显微镜对不同退火温度下的组织进行了分析,以确定最佳的退火温度。结果表明:6CrW2Si的退火硬度与退火温度有关,随着退火温度的升高,硬度先下降后上升,当退火温度为810℃时,钢材平均硬度值最低(193 HBW左右),球化组织为均匀的球化珠光体组织。

| Abstract: | Tests were annealed under different temperature, for purchasers word-hardness( ≤210 HBW) special requirements satisfaction to determine the eptimal annealing process with the help of metalloscope to analyze annealing shape of 6CrW2Si under different temperature. The result showed that 6CrW2Si annealing hardness was connected with temperature ,with the increase of annealing temperature, the hardness dacreases first and then increases. When annealing temperature is 810℃ , the average hardness of steel products is the lowest( adout 193 HBW) and the structure is uniform spheroidized pearlite. |
