Abstract
A method of producing sectional strips and sectional sheets of different thicknesses over the width, in which at least two metal strips or metal sheets of different widths are joined to each other by roll bonded cladding which thins the thickness of the overlaid strips. One strip is wider than the other strip which is narrower. The two strips are arranged symmetrically to the rolling direction center line. The facing surfaces of the two overlaid strips may be prepared for bonding them. The invention also concerns sectional strips or sectional sheets produced by the method.
Claims13
A method of producing sectional strips and sectional sheets of metal having different thicknesses over a first width of the strip or sheet produced, the method comprising the steps of:
- providing a first strip or sheet having the first width;
- providing a second strip or sheet having a second width which is less than the first width;
- overlaying on the first strip or sheet the entire second width of the second strip or sheet;
- and
- joining the first and the second strips or sheets of different widths by roll bonded cladding;
- and
- reducing the thicknesses of the first and the second strips or sheets by approximately 60% with a constant deformation during the roll bonded cladding.
