添加Al_2O_3颗粒的润滑剂改善了不锈钢杯体在熨烫过程中的抗卡咬性能，提高了杯体的熨烫极限。利用碳化钨搭接模具，研究了石蜡基油中悬浮不同浓度的Al_2O_3颗粒对提高SUS430圆筒形杯咬合前熨烫极限的影响。在运动粘度为5 0 0mm2/S的润滑油中加入标称直径d为0.0 2~4微米的氧化铝颗粒c=2vol%，在10 0mm2/S冲压速度下，杯的熨烫极限为8%，与商品含氯低粘度油的极限相近。降低了基础油的运动粘度。当d=0.2μm，c=0.5%时，运动粘度大于180mm2/S的极限与商品油的极限相近。在d=4μm，c=1ol%时，运动粘度大于10 0mm2/S的极限是有效的。结果表明，采用含有颗粒润滑剂的适当的熨烫条件，可提高熨烫过程中的抗咬合性能。
The seizure resistance in the ironing process of stainless steel cups was improved with lubricants containing Al 2 O 3 particles, and the ironing limit of the cups was increased. The effects of suspending different concentrations of Al 2 O 3 particles in paraffin based oils on increasing the ironing limit of SUS430 cylindrical cups before seizure were investigated using a lapped tungsten carbide die. By containing c= 2vol% of Al 2 O 3 particles having nominal diameter d between 0.02 to 4 micrometres in an oil with a kinematic viscosity of 500 mm 2/s, the ironing limit of the cup was 8% under a punch speed of 100 mm 2/s. The limit was similar to the limit using a commercial low-viscosity oil with chlorine additive. The kinematic viscosity of the base oil was reduced. In d= 0.2 μm and c= 0.5 vol%, the limit of the oil more than kinematic viscosity of 180 mm 2/s was similar to the limit by the commercial oil. In d= 4 μm and c= 1vol%, the limit of the oil having more than kinematic viscosity of 100 mm 2/s was effective. It was found that the seizure resistance in the ironing process was improved by the proper ironing conditions with lubricants containing particles.
