Friction is a fundamental element in the cold rolling process and significantly affects the rolling forces and deformation distributions. During rolling, the use of lubricants is an important part of the manufacturing process in terms of long life of the rolls and minimizing the wear and friction of the steel material. The lubricants used in rolling are petroleum-based and harm the environment and human health. For this reason, in recent years, in terms of sustainability, vegetable lubricants have been used and nanoparticles are doped to bio-based lubricants to reduce friction. In this study, a sustainable nano-additive green lubricant was produced by doping 0.5 wt% oleic acid modified kaolin nanoparticles to vegetable based palm lubricants used in the rolling manufacturing process. The kaolin nanoparticles doped gren lubricant was tested in a two-stand rolling mill. The results obtained were compared with the results obtained under dry conditions and with palm lubricant without additives. It was found that kaolin nanoparticles doped lubricants reduced the rolling force by 35.6% and 20.7%, respectively, compared to dry conditions and conditions using non-doped lubricant. In addition, the average arithmetic roughness (Ra) parameter of the surface also decreased by 29.2% and 38.2% compared to the dry and non-doped lubricant conditions. It was concluded that the use of palm lubricants doped with kaolin nanoparticles in the rolling process resulted in a more homogeneous distribution of the surface roughness profile of the sheet material.
