30CrMnSiA是一种合金结构钢。它具有强度高、冷作硬化倾向性较大等特点,因此给温挤带来了很大的影响。本文根据高温拉伸试验和在不同温度下温挤试验,确定了合理的温挤温度和润滑剂。为了降低变形抗力,提高模具寿命,30CrMnSiA在温挤前一般应进行软化热处理。本文还根据在不同温度下反挤产品进行的机械性能试验,确定了温挤时的强化效果。 30CrMnSiA is an alloy steel. It has high strength, cold hardenability and other characteristics of the larger, so to warm extrusion has brought a great impact. According to the high temperature tensile test and the temperature squeeze test at different temperatures, the reasonable warm extrusion temperature and lubricant were determined. In order to reduce the deformation resistance and improve the life of the mold, 30CrMnSiA should generally be softened before hot extrusion heat treatment. This article also based on the anti-extrusion products at different temperatures under the mechanical properties of the test, to determine the strengthening effect of warm extrusion.
