A simulation model was developed for analyzing the ''roll-kiss'' phenomenon, i.e., a situation where the upper and lower work rolls contact each other in the roll barrel. As a result of the analysis, a theoretical method of providing taper on the work rolls was found. The applicability of the method was experimentally confirmed in a laboratory mill, and the following findings were obtained.
(1) The accuracy of the load of roll-kiss calculation by Hertz's equation proved satisfactory for the practical use.
(2) Analysis using the simulation model revealed two different configurations of roll-kiss.
(3) The experimental results showed that for both configurations of roll-kiss, it is possible to prevent roll-kiss, by giving work rolls the optimum taper predicted from the simulation model.
