  • Control process for continuous skin pass operation for metal strip
    Patent number: 6079242
    Abstract: A method of controlling a continuous skin-pass and reduction operation for a metal strip includes the steps of passing a strip through a gap between working rollers of at least two successive rolling stands, only an upstream one of the stands providing substantial thickness reduction of the strip; determining an extension rate of the strip provided by the upstream stand; determining a tension of the strip downstream of the upstream stand; adjusting the speed of the working rollers of the upstream stand compared to the speed of the working rollers of a downstream one of said stands according to the determination of the extension rate; and adjusting the squeezing force of the upstream stand according to the downstream tension determination. A response time to the step of adjustment of the squeezing force is longer than a response time to the step of adjusting the speed of the working rollers.
