Claims10
A modular rolling mill, comprising:
- a plurality of rolling units arranged along a mill pass line, each rolling unit being independently driven by a dedicated motor and drive train;
- and
- clutches for selectively coupling and de-coupling the drive trains of successive pairs of rolling units, wherein when the clutches disengage, the rolling units are allowed to operate independently while rolling a remaining length of a product through the mill pass line.
A method of rolling a product of finite length through a modular rolling mill comprising a plurality of separately driven rolling units arranged in succession along a mill pass line, said method comprising:
- temporarily coupling successive pairs of said rolling units prior to the arrival of a front end of said product at the first of said rolling units;
- maintaining the coupling of said rolling units until the product front end has cleared the last of said rolling units;
- and then
- de-coupling said rolling units for continued operation in a de-coupled state while rolling a remaining length of said product.
A method of rolling a product of finite length through a modular rolling mill comprising a succession of separately driven rolling units, wherein a speed drop is occasioned by the arrival of a front end of the product at each rolling unit, said method comprising:
- temporarily maintaining successive pairs of said rolling units in a coupled state while front end of said product passes through said rolling mill;
- and
- after the front end of said product has cleared the last rolling unit, de-coupling and maintaining said rolling units in a de-coupled state during the rolling of remainder of said product length through said rolling mill.
