Effect of the plate qualities was studied on property of surface lubrication that is necessary for DI can fabrication.
DI canmaking energy was newly used besides the forming load as a means of evaluation on the property of lubrication. It was found that the value of this energy could be a standard of the evalution to the die life of the commercial DI machine. Therefore this energy was found valid as the means of the valuation of tin plate qualities.
In tin plate qualities the factors that affected DI canmaking energy were tin coating weight, tiniron alloy layer amount, chemical treatment, sheet thickness, temper grade. Surface roughness of the original sheet was hardly effective on DI canmaking energy.
But it was considered that surface roughness was effective on the die life. Because surface roughness was effective on the tin corevage of the can wall at DI process.
