摘要/Abstract

摘要： 中碳Cr-Ni-Mo合金钢用50kg真空感应炉冶炼,并通过Gleeble-3800试验机测定了该试验钢在600～1400℃的力学性能-最大力值(载荷)和断面收缩率。试验结果表明,中碳Cr-Ni-Mo钢的脆性区(断面收缩率≤60%)为910～700℃,其塑性区为1320～910℃。该钢连铸坯应避免在910～700℃进行矫直,以便减少铸坯裂纹。

Abstract: The medium carbon alloy steel Cr-Ni-Mo was melted by a 50 kg vacuum induction furnace, and the mechanical properties of test steel-maximum load and reduction of area at 600～1400 ℃ have been measured by Gleeble-3800 test machine. The test results showed that brittle region(reduction of area ≤60%)of the medium carbon Cr-Ni-Mo steel was 910~700 ℃ and its plastic region was 1320~910 ℃.Its cast billet shouldn't be straightened at 910~700 ℃ in order to decrease cast billet crack.
