| 摘 要： | 研究了60Si2MnA线材控轧控冷工艺参数对所析出的珠光体的影响.结果表明:在其他工艺参数相同的情况下,珠光体平均片层间距主要取决于吐丝到集卷过程的冷却,这一过程冷速越快,珠光体平均片层间距越小;珠光体平均片层间距随着吐丝温度或终轧温度的升高呈下降的趋势;终轧后快冷容易出现退化珠光体,并且其含量随相变区冷速的加快而明显增多;较低的终轧温度使珠光体球团直径明显减小.

| Abstract: | The effect of controlled rolling and cooling process parameters on the precipitated pearlite of 60Si2MnA spring steel wire rods is carefully investigated. Experimental results show that when other process parameters are alike, the interlamellar pearlite spacing of 60Si2MnA wire rods is mainly determined by cooling rate in the process from the rod layer to the coil collecting station. The more rapid the cooling rate in this process, the thinner the interlamellar pearlite spacing. The interlamellar pearlite spacing tends to reduce with the increase of finishing temperature or rod-laying temperature. The degenerative pearlite emerges especially after cooling at a rapid rate and its content increases with the elevation of cooling rate after finish rolling. The pearlite colony becomes small obviously at a low finishing temperature. |
