摘要
论述了国外玉米免耕播种机破茬圆盘刀的材料、组织和性能特点,并在此基础上确定了适于我国的圆盘刀材质,通过对其采用不同的热处理工艺参数来分析它的性能变化,最终得到使圆盘刀性能最佳的热处理参数。
In this paper,material and properties of foreign stubble breaking disc were discussed. Based on this,disc＇s material suitable for China had been determined. In addition,disc＇s performance changes under different heat treatment parameters were analyzed. Finally optimum heat treatment parameters had been obtained.
