Roll pass design is an essential part of long product rolling process, since the long products are rolled between the shaped rolls in the long product rolling mills. roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size.

Aluminum hot rolling mill highquality product, maximum yield, superior flexibility primetals technologies providesull range of aluminum hot rolling mills for both new and revamp projects. with our flexible mill configuration, highquality strip can be rolled in capacities between 100,000 to 800,000 tonnes per annum.

Inolling mill havingair of working rolls andair of back up rolls, the working rolls are respectively shifted axially according to the varying plate width oftrip material being rolled to make the contact length of rolls, defined by said working rolls, substantially equal to the plate width of said strip material, whereby accurate flatness control of the rolled strip becomes.

Primetals technologies providesull range of aluminum hot rolling mills for both new and revamp projects. with our flexible mill configuration, highquality strip can be rolled in capacities between 100,000 to 800,000 tonnes per annum. as demand for quality and quantity of rolled aluminum increases so do the demands on production equipment.
