| 摘 要： | 基于离异共析原理,在实验室条件下试验研究了CSP流程生产的SKS51合金工具钢(/%:0.75～0.85C、O.20～O.50Cr、1.30-2.00Ni)4 mm板快速球化退火生产工艺。结果表明,此钢种经奥氏体化温度730℃、保温10 min随炉冷却到650℃等温球化120 min后,剩余未溶碳化物颗粒最多且分布均匀弥散,获得了较好的球化组织。该快速球化退火工艺与传统球化退火工艺相比,节能降耗并提高生产效率。

| Abstract: | Based on devoiced eutectoid transformation(DET) principle,the fast spheroidizing annealing process for 4 mm plate of alloy tool steel SKS51(/%:0.75～0.85C,0.20～0.50Cr-1.30～2.00Ni) produced by CSP line has been tested and studied in laboratory.Results show that with austenizing at 730℃for 10min then cooling in furnace to 650℃isothermal -spheroidizing for 120min,the steel gets better sphroidal structure with more uniform-distributing residual carbide particles.As compared with traditional spheroidizing annealing process the fast spheroidizing annealing process can save energy and reduce consumption and increase productivity. |
