Studies on the Three-Dimentional Deformation in Rolling : 2nd Report, Theoretical Study on the lateral Spread in Hot Rolling

Abstract

It was impossible to study the lateral spread during the rolling analytically, because in the conventional studies for rolling it used to be treated as a two-dimentional problem. The author adopted the mean slipping angle between the rolls and plate and developed the three-dimentional consideration of rolling stresses in the first report. Using these results the author has obtained a new formula of spread during the hot rolling as follow : [numerical formula] then [numerical formula] and [numerical formula] The validity of new formula is also discussed in this report, using the plasticine which has same plastic behavior of steel in hot states.
