| Abstract: | The control system of a hot continuous middle width strip mill is introduced.Computer configuration and the way of communication is presented.The speed control strategy of mills and tabs in rough rolling section and APC strategy are given.Magnetostrictive position sensor is applied in rolling,which improving the precision of measurement of roll gap.Full automatic rolling strategy and program design of rough rolling section are presented.Considering the probably"necking down"caused by the impact of looper when they get contact,"soft touch"control is given;Fuzzy micro-tension control applied to the finish mills without looper and rough mills is introduced. |
