摘　　要：对40Cr、1Cr18Ni9Ti钢温挤压润滑剂应用研究,发现不同成分的润滑剂其润滑效果具有很大的区别。挤压温度低于400℃时,各种润滑剂均具有较低的摩擦因数,石墨系润滑剂的摩擦因数最低,润滑效果相对最好;挤压温度高于400℃时,石墨系润滑剂仍保持较低的摩擦因数,PbO的摩擦因数增加最快。Lubricants in warm extrusion process and dies made of 40Cr and 1Cr18NigTi steel were researched. The results show that the effects of different lubricants are unlike. When warm extru- sion temperatures are below 400℃, the friction factors of diversified lubricants are lower, while graphite lubricants have the lowest friction factors and best lubricating effects. When warm extrusion temperatures are above 400℃, the friction factors of graphite lubricants still keep lower, but that of lead monoxide increases quickly.
