摘　　要：扁挤压筒是多层套装 ,内筒非圆的筒体 ,是生产大型材的重要工模具 .由于扁挤压筒要在十分苛刻的条件下工作 ,合理地选择扁挤压筒用材是十分必要的 .研究了国产H13钢的热处理制度 .运用正交分析法确定了试验方案 .对H13钢真空热处理后的室温及高温机械性能进行了研究 ,得到H13钢在不同热处理制度下σb、σ0 .2 、δ5 、ψ、Aku2 的变化规律 .最后得到了H13钢的最佳热处理工艺 .与国外的H13钢进行对比试验的结果表明 。The flat container, which is a container with multi layer and non circular inner hole, works at very hard condition. So it is necessary to select a kind of appropriate material for the container. In present day, (H13) steel is always applied to inner layer of flat container. Presents the heat treatment of 4Cr5MoV1Si (H13) steel and the investigation of its mechanical properties at room and high temperature after the vacuum heat treatment to obtain.σ b ,σ 0.2 ,δ 5, ψ and A ku2 and the optimum heat treatment technology and concludes from test results that the properties of H13 steel made in China are near to imported ones.
