Abstract: To ensure consistent speed of the steel strip during running of the slitting line,beside of PLC-based accumulator control,the easy-to-use single-chip microcomputer-based control technique can also be employed for the purpose.Here in the paper,the said control method with MCS-51 single-chip microcomputer is described,detailing the operation principle and processes,design structures of the softwares and hardwares as well as the processing techniques involved..
