INVESTIGATION ON NEW HIGH-MOLECULAR LUBRICATION PROCESS FOR SEAMLESS STEEL PIPE COLD-ROLLING (DRAWING)

The high-molecular lubrication process for seamless steel pipe cold-rolling (drawing) is put forward, and its PL film features and its industrial experiments are described. The experiments show that the process can fully meet the requirements of steel pipe cold-rolling (drawing) with advantages such as convenient operation and less environment pollution and also can substitute for the traditional phosphorizing-saponifying process.
