1450 Six-High Reversing Cold Mill

Cold-rolled steel products begin as hot rolled pickled and oiled coils. These coils are "coldreduced" by subjecting them to a cold reduction process on a reversing mill under tension and pressure. This process produces a steel which is in a highly strained condition with very little ductility and is said to be "full hard".

Six-High Mills feature a side-shift mechanism of intermediate rolls;complimented by full positive and negative bending of both intermediate and work rolls. This results in a highly flexible adaptation of the roll gap geometry to variety of strip profiles. This flexibility is the adavantage of the six-high with regard to a rolling process with varying strip widths,gauges,material properties and small lot sizes.

Available size range:

Applications :

· - household appliances,
· - automotive and truck parts,
· - drums and pails,
· - tubing,
· - strapping,
· - office furniture,
· - coil coating,
· - re-rolling for further manufacture.

Outstanding advantages of the RIAMB Six-High Technology:

· - Simplified roll grind geometry
· - Automated work roll offset to the exit side
· - Axial intermediate roll shifting in stationary roll chocks
· - Roll bending forces activated through the bearing center lines
· - Hysteresis free transition from positive to negative bending
· - Direct gauge control via gap measurement between the backup roll chocks

RIAMB Six-High Technology is specially recommended for the following customer requirements:

· - Highest flexibility for quick adaptation to varying production requirements
· - Less work roll changes are required
· - Improved pass reduction by minimized work foll diameter
· - Continuous roll gap adaptation to the strip profile variations
